The male reproductive system includes internal structures like the testes, epididymis, ductus deferens, seminal vesicles, prostate, and penis. The testes are held in the scrotum and produce sperm. Sperm travel through the epididymis, ductus deferens, and ejaculatory duct before mixing with fluids from the seminal vesicles and prostate to form semen, which is ejaculated through the urethra in the penis during orgasm. Blood flows into the structures via internal iliac arteries and drains via internal iliac veins. Lymphatic drainage is to internal and external iliac lymph nodes.
The document discusses the male reproductive system, including its organs and functions. It identifies the testes, epididymis, vas deferens, seminal vesicles, prostate gland, and bulbourethral glands as the internal organs that produce, store, and transport sperm. It describes sperm production through spermatogenesis in the seminiferous tubules and storage in the epididymis, and it traces the pathway of sperm from the testes through the vas deferens and urethra during ejaculation.

This document provides an overview of the male reproductive system. It describes both the external structures, which include the penis and scrotum, and the internal structures, which are the testes, epididymis, vas deferens, and accessory sex glands including the seminal vesicles, prostate gland, and bulbourethral glands. The testes produce both sperm and the hormone testosterone. Sperm mature as they pass through the epididymis and are stored in the vas deferens until ejaculation. The accessory glands secrete fluids that nourish the sperm and form the bulk of the semen.
The document summarizes the major organs of the female reproductive system. It describes how the ovaries produce eggs and hormones, the fallopian tubes catch eggs and transport them to the uterus, the uterus provides a protective environment for embryo implantation and fetal development, and the vagina is the birth canal. The cervix acts as a passageway during birth and the endometrial lining thickens each month to potentially support implantation of a fertilized egg.
The document provides details about the female genital system, including the internal organs like the uterus, vagina, fallopian tubes, and ovaries. It describes the structure of the uterus including its layers, parts, positions, blood supply, and how it enlarges during pregnancy. It also discusses the structure of the vagina, its interior regions, relations to surrounding organs, blood supply, and supports. The summary focuses on the key internal female reproductive organs and some of their key anatomical features.
The male reproductive system has the sole function of producing sperm and delivering it to females. The testes produce sperm through spermatogenesis within seminiferous tubules. Mature sperm travel through the epididymis, vas deferens, seminal vesicles, prostate gland, and urethra, where they mix with fluids before being ejaculated via the penis. The process takes about 74 days and requires a temperature slightly below normal body heat.
The male reproductive system consists of both primary and secondary organs. The primary organs are the testes, which produce sperm and the hormone testosterone. Secondary organs include ducts like the epididymis and vas deferens that transport sperm, as well as accessory glands like the seminal vesicles and prostate gland that provide fluids to nourish and protect sperm. The external genitalia are the penis and scrotum. The primary roles of the male reproductive system are production and transportation of sperm and depositing sperm in the female reproductive tract during sexual intercourse.
The document summarizes the key parts and functions of the female reproductive system. It describes how the ovaries produce eggs and hormones, the fallopian tubes transport eggs to the uterus, and the uterus provides nourishment for a developing fetus. It also outlines the menstrual cycle and explains how the release of eggs, changes in hormones, and shedding of the uterine lining occur in a monthly cycle. Finally, it briefly discusses the breasts and their role in lactation after pregnancy.
The document summarizes the male reproductive system. It describes that the main male reproductive organs are the testes, which produce sperm and testosterone.

The reproductive systems of males and females ensure the continuation of species through the production of gametes and sex hormones. In males, the testes produce sperm and male hormones. Accessory organs like the seminal vesicles and prostate gland contribute to semen. Spermatogenesis is the process where sperm develop from spermatogonia in the seminiferous tubules with help from Sertoli and Leydig cells. At ejaculation, sperm and fluids are released. In females, the ovaries produce eggs and female hormones. The fallopian tubes, uterus, cervix and vagina form the female reproductive tract, while the labia, clitoris and breasts also play roles in reproduction.
The document summarizes the normal menstrual cycle, which typically occurs over 4 phases in a 28 day cycle. It is regulated by the hypothalamus, pituitary gland, and ovaries. The follicular phase begins with menstruation and involves follicle development and estrogen rise. Ovulation occurs around day 14 when an egg is released. In the luteal phase, the corpus luteum forms and secretes progesterone to thicken the uterine lining. If implantation does not occur, progesterone drops and menstruation begins, restarting the cycle.

The urinary system consists of two kidneys, two ureters, a urinary bladder, and a urethra. The kidneys filter waste from the blood to produce urine. The ureters carry urine from the kidneys to the bladder. The bladder stores urine until urination, at which point urine passes through the urethra and out of the body. Together these structures work to regulate fluid balance and remove waste via urine production and storage.
The male reproductive system includes the testes, which produce sperm and testosterone. The testes are located in the scrotum outside of the body to regulate temperature for sperm production. During ejaculation, sperm travel from the testes through the vas deferens, seminal vesicles, prostate, and urethra, where semen containing sperm is expelled through the penis. The penis contains erectile tissue that fills with blood to cause an erection, which is needed for sexual intercourse and ejaculation.
The urinary system, also known as the renal system or urinary tract, consists of the kidneys, ureters, bladder, and the urethra. The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH.

The male reproductive system consists of both internal and external organs. The testicles produce sperm and testosterone, while the seminal vesicles and prostate gland produce seminal fluid. Together, sperm and seminal fluid form semen. During sexual arousal, the penis becomes erect, allowing for the delivery of semen via the urethra. Tobacco and alcohol use can negatively impact the male reproductive system by reducing sperm production, affecting hormone levels, and potentially causing erectile dysfunction.
The document summarizes the male and female reproductive systems. The male reproductive system includes the testes, which produce sperm, and the duct system including the vas deferens and epididymis, which transports and matures sperm. The female reproductive system includes the ovaries, which produce eggs, the fallopian tubes where fertilization occurs, and the uterus which nourishes a developing fetus. Fertilization happens when a sperm enters an egg in the fallopian tubes, forming a zygote that implants in the uterus.
The male reproductive system includes internal structures in the abdomen and pelvis and external structures. The testes produce sperm and are held in the scrotum outside of the body. Sperm travel from the testes through the epididymis, vas deferens, seminal vesicles, and prostate gland before being ejaculated through the urethra in the penis. During ejaculation, muscles contract and glands secrete fluids to form semen, which carries sperm from the male body. The penis is the external organ of copulation and urination in males.

The urinary bladder is a musculomembranous sac located in the pelvis that acts as a reservoir for urine. The bladder expands upward into the abdomen as it fills with urine. The urethra begins at the base of the bladder and exits through the urethral orifice, differing in length and path between males and females. The bladder and urethra are supplied by nerves from the pelvic plexus and receive blood from the internal iliac arteries.
The urinary system consists of two kidneys, two ureters, one urinary bladder, and one urethra. The kidneys filter the blood and produce urine by regulating ions, volume, pH, and producing hormones. Urine passes from the kidneys to the bladder via the ureters. The bladder stores urine which is then expelled through the urethra. The functional unit of the kidney is the nephron, which filters blood and reabsorbs needed substances while secreting waste for urine production.
The male reproductive system functions to produce, store, nourish, and transport gametes and facilitate fertilization. It includes the testes, ducts, accessory glands, and external genitalia. The testes produce sperm through spermatogenesis in the seminiferous tubules. Mature sperm are stored and mature in the epididymis before passing through the vas deferens, seminal vesicles, prostate gland, and urethra to be ejaculated. Hormones regulate sperm production and male sexual characteristics. Common diseases include hydrocele, benign prostatic hypertrophy, prostate cancer, and erectile dysfunction.
The breast is made up of glandular tissue, fibrous tissue, and fatty tissue. In females, the breast fully develops at puberty. The breast extends from the 2nd to 6th ribs and contains 15-20 lobes drained by lactiferous ducts that open onto the nipple. During pregnancy and lactation, the breasts undergo proliferation and changes to support milk production. The blood supply comes from branches of the axillary, internal thoracic, and intercostal arteries, while lymphatic drainage is primarily to the axillary nodes. Breast carcinoma is more common in females and prognosis is generally worse for males. Treatment options for breast cancer include breast-conserving surgery or mastectomy depending on tumor characteristics and

The testes produce sperm and testosterone. They contain seminiferous tubules that produce sperm and Leydig cells that produce testosterone. The epididymis is a coiled tube that stores and transports sperm. The vas deferens carries sperm from the epididymis. The seminal vesicles and prostate gland secrete fluids that nourish and activate sperm. During ejaculation, sperm and fluids pass through the urethra.
The kidneys filter waste from the blood to produce urine, which then travels down the ureters into the urinary bladder. The bladder stores urine until urination, when it is expelled through the urethra. The kidneys and urinary system work together to remove waste from the body and regulate fluid balance and blood pressure.
The prostate is a conical gland that surrounds the urethra in males. It secretes fluid that is slightly acidic and contains substances like zinc that form part of semen. The prostate is located in the pelvis below the bladder and above the urethral sphincter. It has lobes including a median lobe and two lateral lobes. Structures like the urethra and ejaculatory ducts pass through it. The prostate receives blood supply from inferior vesical and internal pudendal arteries and drains into prostatic veins. It is innervated by sympathetic and parasympathetic nerves. The size and structure of the prostate changes with age. Diseases of the prostate include prostat
The uterus is a hollow, pear-shaped organ located in the pelvis that nourishes a developing fetus. It has three parts - the fundus, body, and cervix. The uterus is normally tilted backwards and has broad ligaments that attach it to the pelvic wall. The ovaries are almond-shaped organs located laterally in the pelvis between the broad ligament and ureter. The fallopian tubes connect the ovaries to the uterus and are the site of fertilization. The vagina is a canal that extends from the vulva to the cervix and serves as the organ of birth and copulation.

Firearms can be classified as either smooth-bore or rifled-bore weapons. Smooth-bore weapons like shotguns fire multiple projectiles at once, while rifled weapons like pistols and rifles fire a single bullet. Entry wounds vary based on the firearm caliber and distance, from contact wounds with scorching and blackening to distant wounds with scattered powder markings. Exit wounds show a torn hole dependent on the bullet's momentum and any bone fragments carried with it. Forensic analysis of entry and exit wounds can help reconstruct shooting incidents and determine factors like self-infliction, range, direction, and whether a particular weapon was involved.

1) Heart failure is a condition where the heart cannot pump enough blood to meet the body's needs due to issues with how the heart fills or empties.
2) Common causes include heart attacks, high blood pressure, and heart valve problems.
3) The renin-angiotensin system helps regulate blood pressure and fluid levels in the body and is activated in heart failure. Drugs that block this system such as ACE inhibitors are used to treat heart failure.
1. Arrhythmias occur when the heart beats too fast, too slow, or with an irregular rhythm due to problems with the heart's electrical conduction system.
2. Several classes of antiarrhythmic drugs are used to treat arrhythmias by blocking sodium, calcium, or potassium channels to suppress abnormal automaticity or conduction in the heart.
3. Common antiarrhythmic drugs include quinidine, mexiletine, flecainide, propranolol, amiodarone, dofetilide, verapamil and diltiazem. These drugs have different mechanisms of action and potential side effects like cardiac toxicity that require careful monitoring.
This document discusses antianginal drugs used to treat angina pectoris, or chest pain caused by reduced blood flow to the heart. There are three main classes of drugs used: organic nitrates, beta-blockers, and calcium channel blockers. Organic nitrates like nitroglycerin work by dilating blood vessels to increase blood flow to the heart and reduce its workload. Beta-blockers lower the heart rate and force of contraction to decrease oxygen demand. Calcium channel blockers inhibit calcium entry into heart and blood vessel cells to relax vessels and reduce workload. Each drug class is described in more detail regarding mechanisms, effects, pharmacokinetics, uses, and side effects.
Sickle cell anemia is a hereditary hemolytic anemia caused by a point mutation in the beta globin gene, resulting in abnormal hemoglobin S. This leads to polymerization of hemoglobin and distortion of red blood cells. Clinical manifestations include anemia, bone pain, acute chest syndrome, and organ damage to tissues like the spleen, liver, and kidneys. The condition is diagnosed through blood tests detecting hemoglobin electrophoresis patterns and genetic testing.
Forensic medicine the medico-legal autopsyMBBS IMS MSU
ย
The document summarizes the key steps and components of a medico-legal autopsy, including:
1) Obtaining social, medical, and psychiatric history from relatives, medical records, and police reports to understand the context of the death.
2) Identifying the deceased through visual recognition, personal effects, medical records, and fingerprints.
3) Examining the deceased's clothing and personal effects for clues about their lifestyle and the events surrounding their death.
4) Conducting an external examination of the body and documenting any injuries, markings, or other observations.
5) Performing an internal examination of the body to describe any natural diseases, injuries, or other findings.
6) Determining the cause

Animal activity after death can cause superficial tissue damage resembling abrasions on bodies found in sandy locations. Insects, ants, beetles and other scavengers will invade the body. In more covered places, mammals like rats, mice, dogs and foxes may feed on bodies when food supplies are low, destroying large areas. Birds like buzzards and crows can pick a body clean in a few days depending on the season. Water bodies host crustaceans, fish and birds that can cause extensive soft tissue damage, with characteristic marks. During autopsy, pathologists must be careful not to misinterpret accidental bone fractures or tissue damage caused by their own actions as injuries. Clinicians' resuscitation efforts or diagnostic techniques ante
The document discusses anemia, including its causes, types, diagnosis, and treatment. It defines anemia as a low red blood cell count or low hemoglobin levels. The main causes are blood loss, decreased red blood cell production, and increased red blood cell destruction. Anemia can be classified as microcytic, macrocytic, or normocytic based on red blood cell size. Treatment involves iron supplements in the form of ferrous sulfate, though some patients require alternative preparations due to side effects. Precautions are needed as iron can be toxic in high doses.
Skeletal muscle relaxants are drugs that affect skeletal muscle function by decreasing muscle tone. There are two main types: neuromuscular blockers that interfere with transmission at the neuromuscular junction and have no central nervous system activity, often used during surgery; and centrally-acting muscle relaxants that are used to alleviate musculoskeletal pain and spasms by acting in the central nervous system. Anemia is a condition in which the number of red blood cells or their oxygen-carrying capacity is insufficient, defined as a hemoglobin level below 13 g/dL for men and 12 g/dL for non-pregnant women. Anemia can be caused by blood loss, decreased red blood cell production, or increased red
Parkinsonism is a progressive neurological disorder characterized by bradykinesia, muscular rigidity, resting tremor, and impaired balance. It can be caused by idiopathic Parkinson's disease, vascular issues, certain drugs that block dopamine, or dementia with Lewy bodies. Treatment aims to increase dopamine in the brain and involves levodopa, dopamine agonists, MAO inhibitors, COMT inhibitors, amantadine, and anticholinergic drugs.
Medical negligence occurs when a doctor breaches his duty of care owed to a patient, resulting in injury to the patient. For a claim of medical negligence to be successful, it must be proven that the doctor owed a duty of care, breached this duty, and this breach caused damages to the patient. Breaches of duty can include failing to follow approved medical practices, making inaccurate diagnoses, risks associated with treatment, and failing to communicate with other doctors. The standard of care owed depends on the doctor's specialty and level of experience. Between 1985-1989, the Malaysian Medical Council inquired into 36 cases of medical negligence and disciplinary issues, finding 21 practitioners guilty as charged.
Forensic medicine medical negligence 2-bolam principleMBBS IMS MSU
ย
This document discusses medical negligence and the Bolam principle for determining negligence in medical malpractice cases. It provides background on several key cases that helped establish the standard of care. The Bolam principle determines negligence based on whether a doctor's actions fell below the standard of a responsible body of medical professionals. However, it has been criticized for being too protective of doctors. Even if a doctor's actions cause harm, they may not be found negligent under Bolam if other doctors may have acted the same way. The document examines challenges in assessing causation and damages in medical negligence cases.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the bodyโs response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

Temple of Asclepius in Thrace. Excavation resultsKrassimira Luka
ย
The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).
2. Male Reproductive System The reproductive system in men has components in the abdomen, pelvis, and perineum.
3. Male Reproductive System The major components are a testis, epididymis, ductus deferens, and ejaculatory duct on each side, and the urethra and penis in the midline. Three types of accessory glands are associated with the system: A single prostate; A pair of seminal vesicles; A pair of bulbourethral glands.
5. The scrotum The scrotum is an outpouching of the lower part of the anterior abdominal wall. It contains the testes, the epididymides, and the lower ends of the spermatic cords.
6. The scrotum It is divided on its surface into two compartments by a raphรฉ, which is continued forward to the under surface of the penis, and backward, along the middle line of the perineum to the anus. Each compartment contains one of the two testes, and one of the epididymides.
7. The scrotum The wall of the scrotum has the following layers: Skin Superficial fascia Spermatic fasciae Tunica vaginalis
8. The scrotum Skin The skin of the scrotum is thin, wrinkled, and pigmented and forms a single pouch. A slightly raised ridge in the midline indicates the line of fusion of the two lateral labioscrotal swellings. Superficial fascia This is continuous with the fatty and membranous layers of the anterior abdominal wall. The fat is replaced by smooth muscle called the dartos muscle. This is innervated by sympathetic nerve fibers and is responsible for the wrinkling of the overlying skin.
9. The scrotum Spermatic fasciae It has three layers which lie beneath the superficial fascia and are derived from the three layers of the anterior abdominal wall on each side. The external spermatic fascia is derived from the aponeurosis of the external oblique muscle; the cremasteric fascia is derived from the internal oblique muscle; and, finally, the internal spermatic fascia is derived from the fascia transversalis. Tunica vaginalis This lies within the spermatic fasciae and covers the anterior, medial, and lateral surfaces of each testis.
10.
11. Lymph Drainage of the Scrotum Lymph from the skin and fascia, including the tunica vaginalis, drains into the superficial inguinal lymph nodes .
12. Testes Testis has ellipsoid-shaped. Testes develop in the abdomen and move before birth into the scrotum. The left testis usually lies at a lower level than the right.
13. Testes The testis are covered by: A closed sac of peritoneum (the tunica vaginalis), which originally connected to the abdominal cavity. Normally after testicular descent, the connection closes, leaving a fibrous remnant. It is covered by a fibrous capsule called the tunica albuginea.
15. Testes In the inner surface of the capsule is a series of fibrous septa that divide the interior of the organ into lobules. Lying within each lobule are 1 to 3 coiled seminiferous tubules. The tubules open into a network of channels called the rete testis. Small efferent ductules connect the rete testis to the upper end of the epididymis.
17. Epididymis The epididymis is a single, long coiled duct that courses along the posterolateral side of the testis. The tunica vaginalis covers the epididymis with the exception of the posterior border.
19. Epididymis It has two distinct components: The efferent ductules, which form an enlarged coiled mass that sits on the posterior superior pole of the testis and forms the head of the epididymis; The true epididymis, which is a single, long coiled duct into which the efferent ductules all drain, and which continues inferiorly along the posterolateral margin of the testis as the body of epididymis and enlarges to form the tail of epididymis at the inferior pole of the testis.
20. Arterial Blood Supply of the Testis and Epididymis The testicular artery is a branch of the abdominal aorta.
21. Venous drainage of the Testis and Epididymis The testicular veins emerge from the testis and the epididymis as a venous network, the pampiniform plexus. This becomes reduced to a single vein as it ascends through the inguinal canal. The right testicular vein drains into the inferior vena cava, and the left vein joins the left renal vein.
22. Lymphatic Drainage of The Testes Lymphatic drainage of the testes is to the para-aortic lymph nodes.
23. Ductus deferens (Latin: "carrying-away vessel"), also called vas deferens. The ductus deferens is a long muscular duct that transports spermatozoa from the tail of the epididymis to the ejaculatory duct.
24. Ductusdeferens course The vas arises from the tail of the epididymis and traverses the inguinal canal to the deep ring, passes downwards on the lateral wall of the pelvis almost to the ischialtuberosityand turns medially to cross the ureter posterior to the bladder. It continues inferomedially along the base of the bladder, anterior to the rectum, almost to the midline, where it is joined by the duct of the seminal vesicle to form the ejaculatory duct.
25. Ductusdeferens course The terminal part of the vas deferens is dilated to form the ampulla of the vas deferens. The ejaculatory duct penetrates through the prostate gland to connect with the prostatic urethra.
26. Seminal vesicle The seminal vesicles are an accessory gland of the male reproductive system . The seminal vesicles are two lobulated organs about 2 in. (5 cm) long lying on the posterior surface of the bladder .
27. Seminal vesicle On the medial side of each vesicle lies the terminal part of the vas deferens. Posteriorly, the seminal vesicles are related to the rectum. Inferiorly, each seminal vesicle narrows and joins the vas deferens of the same side to form the ejaculatory duct.
28. Blood Supply of Seminal vesicle Arteries The arterial blood supply from, the inferior vesicle and middle rectal arteries. Veins The veins drain into the internal iliac veins.
29. Ejaculatory Ducts The two ejaculatory ducts are each less than 1 in. (2.5 cm) long and are formed by the union of the vas deferens and the duct of the seminal vesicle. The ejaculatory ducts pierce the posterior surface of the prostate and open into the prostatic part of the urethra, close to the margins of the prostatic utricle; their function is to drain the seminal fluid into the prostatic urethra.
30.
31. Prostate The prostate is an unpaired accessory structure of the male reproductive system that surrounds the urethra in the pelvic cavity . It lies immediately inferior to the bladder, above the theurogenitaldiaphragm, posterior to the pubic symphysis, and anterior to the rectum.
32. Prostate The prostate is shaped like an inverted rounded cone with a larger base, which is continuous above with the neck of the bladder, and a narrower apex, which rests below on the pelvic floor. The inferolateral surfaces of the prostate are in contact with the levatorani muscles that together cradle the prostate between them.
34. Prostate The two ejaculatory ducts pierce the upper part of the posterior surface of the prostate to open into the prostatic urethra at the lateral margins of the prostatic utricle.
35. Relations of Prostate Superiorly The base of the prostate is continuous with the neck of the bladder. The urethra enters the center of the base of the prostate. Inferiorly The apex of the prostate lies on the upper surface of the urogenital diaphragm. The urethra leaves the prostate just above the apex on the anterior surface
36. Relations of Prostate Anteriorly The prostate is related to the symphysispubis. The prostate is connected to the posterior aspect of the pubic bones by the puboprostatic ligaments. Laterally The prostate is embraced by the anterior fibers of the levatorani. Posteriorly The prostate is closely related to the anterior surface of the rectal ampulla and is separated from it by the rectovesical septum (fascia of Denonvilliers).
37. Structure of the Prostate Enclosed within thin dense fibrous capsule Inner loose sheath derived from pelvic fascia โ โprostatic sheathโ Continuous inferiorly with superior fascia of urogenital diaphragm Posteriorly it is part of rectovesical septum Separates bladder, seminal vesicles and prostate from rectum Prostatic venous plexus lies between fibrous capsule and prostatic sheath.
38. Structure of the Prostate Prostatedivided into: Two lateral lobes One median lobe Anterior and posterior lobes
39. Structure of the Prostate Anterior Tissue lying anterior to urethra No glands; fibromuscular tissue only Median Cone-shaped region between ejaculatory ducts and urethra Lateral (left & right) Main mass of gland, continuous posteriorly Separated by prostatic urethra Posterior Describes postero-medial part of lateral lobes palpable through rectum on DRE.
41. Blood Supply of The Prostate Arterial supply Arteries derived from internal pudenal, inferior vesical and middle rectal arteries (branches of internal iliac) Venous drainage Veins form prostatic venous plexus around sides and base of prostate โ located between capsule and sheath Drains into internal iliac veins Also communicates with vesical venous plexus and vertebral venous plexuses.
42. Lymphatics and innervation of The Prostate Lymphatic drainage Lymph vessels terminate in internal iliac and sacral lymph nodes Some vessels from posterior surface pass with lymph vessels from bladder to external iliac LNโs Innervation Parasympathetic fibres arise from pelvic splanchnic nerves Sympathetic fibres from inferior hypogastric plexuses

44. Penis The penis is a pendulous organ suspended from the front and sides of the pubic arch and containing the greater part of the urethra.
45. Penis It consists of internal root, external shaft, & glans. Root: the portion of the penis that extends internally into the pelvic cavity. Shaft: the length of the penis between the glans and the body. Glans: the head of the penis; has many nerve endings. Foreskin: a covering of skin over the penile glans.
47. Penis The root of penis consists of the two crura, which are proximal parts of the corpora cavernosaattached to the pubic arch, and the bulb of penis, which is the proximal part of the corpus spongiosumanchored to the perineal membrane.
48. Penis The body of the penis is essentially composed of three cylinders of erectile tissue enclosed in a tubular sheath of fascia (Buck's fascia). The erectile tissue is made up of two dorsally placed corpora cavernosa and a single corpus spongiosum applied to their ventral surface . At its distal extremity, the corpus spongiosum expands to form the glans penis, which covers the distal ends of the corpora cavernosa. On the tip of the glans penis is the slitlike orifice of the urethra, called the external urethral meatus.
50. External penile structures Corona: the rim of the penile glans. Frenulum: thin strip of skin connecting the glans to the shaft on the underside of the penis. Both are highly sensitive areas to the touch
51. Blood Supply of The Penis Arteries The corpora cavernosa are supplied by the deep arteries of the penis ; the corpus spongiosum is supplied by the artery of the bulb. In addition, there is the dorsal artery of the penis. All the above arteries are branches of the internal pudendal artery. Veins The veins drain into the internal pudendal veins.
52. Lymphatics and innervation of The Penis Lymph Drainage The skin of the penis is drained into the medial group of superficial inguinal nodes. The deep structures of the penis are drained into the internal iliac nodes. Nerve Supply Sensation The nerve supply is from the pudendal nerve and the pelvic plexuses. Erectile function Parasympathetic(excitatory) Sympathetic (inhibitory)
