The document summarizes the male and female reproductive systems. It describes key parts of both systems including the penis, testes, prostate gland, and seminal vesicles in males. In females, it outlines the breasts, ovaries, uterus, fallopian tubes, and vagina. It also explains processes like spermatogenesis, ovulation, fertilization, menstruation, and menopause. The reproductive system allows genetic material to pass from parents to offspring, ensuring continuation of the species.
he reproductive system is a collection of internal and external organs — in both males and females — that work together for the purpose of procreating, according to the Cleveland Clinic. Due to its vital role in the survival of the species, many scientists argue that the reproductive system is among the most important systems in the entire body.

The human reproductive system includes the male reproductive system which functions to produce and deposit sperms; and the female reproductive system which functions to produce egg cells, and to protect egg cells, and to protect and nourish the fetus until birth.
The reproductive system is the human organ system responsible for the production and fertilization of gametes (sperm or eggs) and, in females, the carrying of a fetus. Both male and female reproductive systems have organs called gonads that produce gametes.
Human reproduction - A detailed study ( medical information)martinshaji
Human reproduction is any form of sexual reproduction resulting in human fertilization. It typically involves sexual intercourse between a man and a woman. During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization of the woman's ovum by the man's sperm.
By the end of this section, you will be able to:
Describe human male and female reproductive anatomies
Describe spermatogenesis and oogenesis and discuss their differences and similarities
Describe the role of hormones in human reproduction
Describe the roles of male and female reproductive hormone
The reproductive events in humans include formation of gametes (gametogenesis), i.e., sperms in males and ovum in females, transfer of sperms into the female genital tract (insemination) and fusion of male and female gametes (fertilisation) leading to formation of zygote.
this is a long study on all aspects of human reproduction & most asked questions about human reproductive system ( medical information ).

Reproduction is the process that continues life on Earth
Males and females each have structures specialized for their roles in reproduction.
Hormones are the key to how the human reproductive system functions,
Sex hormones are necessary for the development of sexual characteristics, such as breast development in females and facial hair growth in males.
Hormones from the pituitary gland also begin the production of eggs in females and sperm in males. Eggs and sperm transfer hereditary information from one generation to the next.
this chapter is completely based on complete process of reproduction from insemination to lactation,the diagrams and differences and explanations according to NCERT Syllabus.
Located outside the abdominal cavity within a pouch called scrotum.
Scrotum provides low temperature required for spermatogenesis.
Each testis is about 4 to 5 cm length and 2 to 3 cm width.
Each testis has about 250 compartments called testicular lobules.
Each lobule contains one to three seminiferous tubules.
Seminiferous tubules lined by male germ cells and Sertoli cells.
Male germ cell undergoes meiosis and produce sperm.
Sertoli cells provide nutrition to the germ cell and the sperm.
In between the seminiferous tubule there is interstitial cell or Leydig
cell.
Leydig cells produce testicular hormones
called androgen (testosteron It is the primary female sex organs that produce the female
gamete (ovum).
It also produces several steroid hormones.
The ovaries located in the lower abdomen.
Each ovary is about 2-4 cm in length.
Connected to the pelvic wall and uterus by ligaments.
Each ovary is covered by thin epithelium which encloses the
ovarian stroma
The ovarian stroma has two zones
A peripheral cortex.
An inner medulla.

Female Reproductive system Slideshare ankitkulpare
The female reproductive system is composed of a pair of ovaries along with oviducts, vagina, cervix, uterus , and external organ that are located in the pelvic region.
This PowerPoint presentation is an overview of the anatomy, physiology and pathophysiology of diseases, and common disorders of the Reproductive System.
The following power point discusses about how the process of sexual reproduction takes place in Humans. In it, we discuss about the male and female reproductive systems, then we discuss about how the process of fertilisation occurs in humans. Thereafter we discuss about pregnancy. Menstrual Cycle, Ways to control Population growth, STDs etc
The female reproductive system contains two main parts: the uterus, which hosts the developing fetus, produces vaginal and uterine secretions, and passes the anatomically male sperm through to the fallopian tubes; and the ovaries, which produce the anatomically female egg cells.

Microteaching is a unique model of practice teaching. It is a viable instrument for the. desired change in the teaching behavior or the behavior potential which, in specified types of real. classroom situations, tends to facilitate the achievement of specified types of objectives.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection
2. Reproductive system
Reproduction: It is defined as the process by which
genetic material is passed from one generation to
another generation thus maintains the continuation
of species.
OR
Is a biological process by which new offspring (new
individual organism) are produced from their
parents.
It typically involves sexual intercourse between the
male and female reproductive systems.
During sexual intercourse the interaction between
the male and female gamete results in fertilization
of the female’s ovum by the male’s sperm.
3.
4. Male reproductive system
1.Penis: It is a copulatory organ which contain
terminal parts of urethra. The expanded portion of
the tip of penis is called Glans penis.
The parts of penis are …
1.Corpora cavernosa: These are two pillars of erectile
tissue lying side by side under the skin of penis
2.Corpora spongiosum: It contains the urethra lies
below corpora cavernosa.
3.Glans penis: It is the enlarge tip of penis.
4.Propuce: It is a fold of skin covering the glans penis.
Function : Introduces sperms into vagina during
copulation
6. 1.TESTIS
Testis are the male reproductive
organ which produce
spermatozoa.(Sperm)
These are two oval shaped bodies
which are covered by
scrotum(2.5oC) by means of
spermatic cords forms bag are
pouch for the two testis.
Seminiferous tubules: In testis a
group of 200-300 cells combined
and form seminiferous tubules.
These produces sperm by
spermatogenesis.
Epididymis: The sperm are
transported out of testis into a
tube called epididymis.
Functionally it is site of sperm
maturation. This continues to
form vas deference.
7. 2.Vas deference: It is the continuation of epididymis.
They get dilate to form ampulla which stores sperms
and conveys sperms from epididymis to urethra.
3.Seminal vesicles: They are two small
fibromuscular pouches which lies at the terminal
part of vasa deference. Both vas deference and
seminal vesicles joins together to form a duct called
as ejaculatory duct.
Function:
It produces secretion which is added to spermatozoa
during ejaculation.
8. Prostate gland
It lies below the bladder in
pelvic cavity. It is pyramidal
in shape.
The prostate gland gradually
increases it’s size from birth
to puberty.
Function: It secrets an alkaline
milky fluid which neutralizes
the acidity of semen and vaginal
secretion thus greatly increases
fertility and motility of
sperms(spermatozoa).
9. Constituents of semen[Alkaline pH 7.2-7.6]
Semen is the fluid ejaculated during
intercourse from urethra. It consist of;
a.Spermatozoa(sperms)
b.Viscous fluid which helps to nourish
sperms
c.Mucus secreted by lining of glands
d.Antibiotic semen plasmin which has
ability to destroy number of bacteria.
10. Spermatogenesis:
It is the process of formation
of motile sperms
(spermatozoa) from
Spermatogonia.
It is fallowed by three phases.
1.Multiplication
2.Growth phase
3.Maturation phase
12. Female Reproductive system
The female genital organs can be classified as.
1. Secondary organs: Breasts(Mammary glands)
2. External genital organs: Mons veneries
Labia majora
Labia minora
Clitoris
Hymen
3. Internal genital organs: Vagina
Uterus
Ovaries
Fallopian tubes
13. Breast (mammary gland)
• Breast is the glandular tissue overlying
on pectoral muscle of chest.
• These are accessory sex organs in female
which secret milk.
• Milk producing part of breast is
organized into 15 -20 sections, called
LOBES. each lobes are made up of
smaller structure called Lobules.
• Milk travels through a network of tiny
tubes called lactiferous ducts, which
passes toward nipple.
Function: After child birth Prolactin of
anterior pituitary secrets the milk while
oxytocin helps to ejaculation.
15. External genital oragn
1.Mons veneris: It is the fat lying in front of
symphysis pubis which is covered with
pubic hair at puberty.
2.Labia majora: They are two large folds
which form the boundary of vulva.
3.Labia minora (nyphae): These are two
small folds of skin situated between the
upper part of labia majora.
3.Clitoris: It is small erectile tissue situated
at the apex of vestibule. It is sensitive and
responses to penis.
4.Hymen: It is a thin mucus membrane
which covers the vaginal orifice. It is
perforated centrally to allow menstrual
discherge.
16. Internal genital oragan
Vagina: It is a canal made of
muscular walls. It extends
from vaginal orifice to
cervix. A small projection of
vagina above the outer
surface of uterus called
fornix.
Uterus: Uterus or womb is a
hallow muscular organ
situated in pelvis. It is
covered by peritoneum. It
lies in between bladder and
rectum.
The uterus divided into 3
parts…
1) Fundus
2) Body
3) Cervix
17. Ovaries: These are two in number . They lie on
either sides of uterus.
The ovary attaches to fallopian tube with the help
of ligament.
Structure of ovary contains…
1.Central soft tissue called stroma
2.An outer surface called Germinal epithelium.
Functions:
1.Formation, development and liberation of ovum
from germinal epithelium
2.Secreion of oestrogen by Graffian follicle
3.Secretion of progesterone by Corpus luteum
18. Fallopian tube(Uterine tube): these two in
number.
They arise from upper angles of uterus
It is made up of fallowing layers
1. Outer peritoneal layer
2.Middle muscular layer
3.Inner mucus layer
Function :
It act as passage for ovum from ovary to uterus.
Fertilization of ova and sperm takes place in this
tube
19. Ovulation:
Maturation of graffian
follicle and liberation of
ovum is termed as ovulation.
The ovary contains graffian
follicles.
These follicles are about
40000 in number they are
formed during fetal life the
rest get degenerated at
menopause.
21. Menstruation:
Menstrual Cycle
It is a cyclic phase of the
flow of blood with sheds of
endometrium from the
uterus woman at monthly
intervals is called.
Phases of menstrual
cycle:
I.Destructive phase
II.Follicular phase
III.Luteal phase
22. I. Destructive phase
II. Follicular phase: It extend for the next 9
days. During this time repair of endometrium
occurs. At this stage graffian follicle of ovary
matures and ova develop inside.
Around the 14th day of menstrual cycle graffian
follicle ruptures and release the ova.
The graffian follicle now becomes corpus leutium.
III. Luteal phase
23. Menopause:
• Is the cessation of women’s reproductive ability.
• It is usually natural change which occurs in
women`s midlife during the late 40`s or early
50s
• It accompanied by following characters
1.Flushing and sweating
2.Shrinking of breast
3.Atrophy of sex organ
4.Episodes of undefined behaviour
