The endocrine system consists of glands that produce hormones and regulate bodily functions. The hypothalamus and hypophysis make up the central regulatory formations of the endocrine system. Peripheral endocrine glands include the thyroid gland, parathyroid glands, adrenal glands, pancreas, gonads, and others. These glands produce hormones that are released into the bloodstream to target and regulate distant tissues and organs. The endocrine system works through feedback loops to maintain homeostasis.

Chapter 11
The document summarizes the key components of the endocrine system. It describes the main endocrine glands - the pineal gland, gonads, adrenal glands, pancreas, thyroid gland, and pituitary gland. It explains that the endocrine glands release hormones directly into the bloodstream, while exocrine glands release secretions through ducts. The pituitary gland is called the "master gland" as it controls many other endocrine glands. In closing, it provides some brief details on each of the main endocrine glands and their functions.
HISTOLOGY OF ADRENAL GLAND & CORRELATION WITH FUNCTION
The adrenal gland has an outer cortex and inner medulla. The cortex is divided into three concentric zones - the zona glomerulosa secretes mineralocorticoids, the zona fasiculata secretes glucocorticoids, and the zona reticulari secretes androgens. The medulla contains chromaffin cells that secrete catecholamines such as epinephrine. Diseases can result from insufficient or excessive secretion from the cortex or medulla.
HISTOLOGY OF ADRENAL GLANDS
The adrenal glands secrete both steroid hormones and catecholamines. They are located above the kidneys and have two distinct regions - the cortex and medulla. The cortex lies beneath the capsule and secretes steroid hormones. The medulla lies deep to the cortex and secretes catecholamines. Although embryologically distinct, the cortex and medulla are functionally related.

The endocrine system consists of glands that secrete hormones directly into the bloodstream. The main endocrine glands are the pituitary gland, pancreas, ovaries, testes, thyroid gland, and adrenal glands. Hyperpituitarism is caused by excess secretion of hormones from the pituitary gland, often due to a pituitary adenoma. Hyperthyroidism occurs when the thyroid gland overproduces thyroid hormones, leading to high levels of thyroxine and triiodothyronine in the bloodstream.
Histology of thyroid gland
This document summarizes the histological structure of the thyroid gland. It notes that the thyroid gland consists of two lobes and an isthmus, and its structural unit is the follicle. Each follicle contains a layer of epithelial cells surrounding a follicular cavity filled with colloid. The epithelial cells are cuboidal and can change shape depending on the gland's activity level. Additionally, parafollicular cells in the interfollicular spaces secrete thyrocalcitonin. The colloid within the follicular cavity is a gel-like secretion composed of nucleoproteins and enzymes used to synthesize thyroid hormones.
Parathyroid
The parathyroid glands are four small glands located behind the thyroid gland, with one at each end of the upper and lower poles of the thyroid. The glands consist of two main cell types: chief cells and oxyphil cells. Chief cells are small polygonal cells that synthesize and secrete parathyroid hormone, which regulates blood calcium levels. Oxyphil cells are larger than chief cells and less numerous.
Histology of thyroid and parathyroid, tongue
The thyroid gland contains follicles that are its functional units. Each follicle contains a colloid core surrounded by a single layer of epithelial cells. The activity level of the follicle determines how cuboidal the epithelial cells appear and the amount of colloid present. Additional cell types include parafollicular cells that secrete calcitonin to lower blood calcium levels. The parathyroid gland contains chief cells that synthesize PTH and oxyphil cells of unknown function, with chief cells being more numerous and smaller than oxyphil cells.
Adrenal glands
The adrenal glands are located above the kidneys and consist of an outer cortex and inner medulla. The cortex secretes mineralocorticoids like aldosterone and glucocorticoids like cortisol. The medulla secretes catecholamines such as norepinephrine and epinephrine. The pancreas contains clusters of cells called islets that secrete glucagon and insulin which regulate blood sugar levels. The ovaries and testes are reproductive endocrine glands. The ovaries secrete estrogens and progesterone while the testes secrete testosterone.

2. the stomach
The document discusses acid production in the stomach. It outlines that the parietal cells in the stomach lining produce hydrochloric acid through a multi-step process involving carbonic acid, hydrogen ions, and chloride ions. Acid production is increased by the hormone gastrin and acetylcholine released by the vagus nerve. It is decreased by hormones like somatostatin, cholecystokinin, and secretin which are released in response to food in the duodenum. The document also reviews questions about this topic.
Endo 3 myka
The document summarizes the trophic hormones secreted by the anterior pituitary gland and their target organs and functions. The anterior pituitary, or adenohypophysis, secretes six trophic hormones: growth hormone, thyroid-stimulating hormone, adrenocorticotropic hormone, follicle-stimulating hormone, luteinizing hormone, and prolactin. These hormones target and stimulate various endocrine glands including the thyroid, adrenal cortex, ovaries, testes, and mammary glands. The hypothalamus regulates secretion of trophic hormones from the anterior pituitary through releasing hormones.
3. the small intestine
The small intestine is responsible for digestion and absorption of nutrients. It has a highly folded mucosa layer containing absorptive enterocytes and secretory goblet and enteroendocrine cells. The enteroendocrine cells secrete hormones like CCK, secretin, and GIP in response to nutrients in the lumen. The small intestine receives pancreatic enzymes and bile, which aid in digestion, through the hepatopancreatic duct. Absorbed nutrients then pass into the bloodstream for use by the body.
Introduction to excretory system
The document provides an introduction to the excretory system, focusing on the anatomy and functions of the kidney. It discusses the following key points:
1. The kidneys regulate homeostasis through fluid balance, electrolyte balance, acid-base balance, and blood pressure regulation. They also excrete metabolic waste and secrete important hormones and vitamins.
2. Each kidney contains around 1 million nephrons, each with a glomerulus for blood filtration and a tubule for reabsorption and secretion.
3. Glomerular filtration occurs through small pores in the filtration membrane, allowing filtration of plasma while retaining blood cells and proteins. Around 180L of filtrate is produced per day through this process.
Histology of endocrine system
The pituitary gland controls many body functions through the release of hormones into the bloodstream. It is located at the base of the skull and has anterior and posterior lobes. The anterior lobe secretes growth hormone and other hormones that target various endocrine glands and body systems. The posterior lobe stores and releases hormones produced by the hypothalamus. The thyroid gland regulates metabolic rate through the hormones thyroxine and triiodothyronine. It has follicles that store and release these hormones into the bloodstream. The adrenal glands sit atop the kidneys and consist of an outer cortex and inner medulla. The cortex secretes corticosteroids and the medulla secretes epinephrine and norepinephrine
Endo 4 jho
The adrenal glands are paired organs that sit atop the kidneys. Each consists of an outer adrenal cortex and inner adrenal medulla. The cortex secretes corticosteroids like aldosterone and cortisol to regulate electrolytes and metabolism. The medulla secretes epinephrine and norepinephrine to increase heart rate and metabolism during stress. The thyroid gland regulates metabolism through thyroxine (T4) and triiodothyronine (T3) production. Hypothyroidism causes low metabolism while hyperthyroidism elevates it. The parathyroid glands secrete parathyroid hormone to regulate blood calcium levels.

Thyroid gland (edited v.)
The thyroid gland is located in the anterior neck region adjacent to the larynx and trachea. It consists of two lobes united by an isthmus. The thyroid gland is composed of follicles made up of follicular cells that synthesize the thyroid hormones thyroxine and triiodothyronine, as well as parafollicular cells that synthesize calcitonin. These hormones regulate growth, metabolism, and calcium levels.
2. micturition
The document discusses the storage and voiding phases of micturition, or urination. During storage, the bladder relaxes and the urethral sphincters contract, allowing urine to be stored. Sympathetic signals relax the bladder and contract the internal urethral sphincter, while somatic signals contract the external sphincter. As the bladder fills, its walls distend to maintain low pressure. During voiding, parasympathetic signals cause the bladder to contract while relaxing the sphincters, allowing urine to be released.
Endocrine organs
This document summarizes the major endocrine organs and their functions. It describes the classification of endocrine organs into central, peripheral, mixed and diffuse systems. It then details the key tissues and cells involved in hormone production for each organ, including the hypothalamus, hypophysis, thyroid gland, parathyroid glands, adrenal glands and pancreas. For each organ, it explains the histology, hormone production and regulation via feedback loops with other endocrine organs like the hypothalamus and hypophysis.

In this presentation, you will get the insight to the kidney as an endocrine gland along with some of its non excretory functions.
Histology of thyroid gland and pineal gland
The document discusses the histology of the thyroid gland, parathyroid gland, and pineal gland. The thyroid gland contains a connective tissue component forming a capsule, septa, and stroma, as well as a parenchymal component consisting of thyroid follicles and parafollicular C cells. The parathyroid gland contains connective tissue and parenchymal chief and oxyphil cells. The pineal gland contains pinealocytes, astroglial cells, and brain sand.
Histological structure of pituitory gland
The pituitary gland, also known as the hypophysis, is located at the base of the brain and has a complex histological structure. It has two main parts - the adenohypophysis and neurohypophysis. The adenohypophysis consists of the pars distalis, pars tuberalis, and pars intermedia. It contains different cell types that secrete various hormones like growth hormone, prolactin, TSH, FSH, and LH. The neurohypophysis is derived from neural tissue and secretes oxytocin and anti-diuretic hormone. The pituitary gland plays an important role in regulating many physiological processes in the body.
Anatomy.pancreas
The pancreas is a J-shaped organ located behind the stomach that produces digestive enzymes and hormones. It has an exocrine function through the production of enzymes that digest food and an endocrine function through clusters of cells called islets of Langerhans that secrete insulin and glucagon to regulate blood sugar levels. The pancreas receives its blood supply from several arteries including the splenic artery and superior mesenteric artery. Diseases of the pancreas include pancreatitis, pancreatic cancer, and conditions that can lead to cancer like chronic pancreatitis.
A&P Chapter 30 The Urinary System
The urinary system consists of organs that produce and excrete urine from the body, including the kidneys, ureters, urinary bladder, and urethra. The kidneys filter waste from the blood to produce urine and are located in the abdominal cavity. Urine forms via filtration, reabsorption, and tubular secretion in nephrons, the functional units of the kidneys. Urine contains water and dissolved waste products and its production and composition can be affected by various disorders and changes over the lifespan.
endocrine system
The document summarizes the major endocrine glands and tissues in the human body. It describes the location and functions of the hypothalamus, pituitary gland, thyroid gland, parathyroid gland, thymus, adrenal glands, pancreas, kidneys, heart, digestive tract, placenta, testes, and ovaries. It also briefly discusses endocrine disorders like acromegaly and cretinism. The endocrine system regulates bodily functions through hormones secreted into the bloodstream from various glands and tissues.
Urinary dent
The urinary system functions to eliminate waste from the body and regulate water balance and electrolyte levels. It consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys contain millions of nephrons, which are the functional filtering units that form urine by selectively reabsorbing useful substances while filtering out waste. Urine is transported from the kidneys to the bladder via the ureters. The bladder stores urine until voiding through the urethra. As we age, urinary function progressively declines as the bladder shrinks and urinary retention becomes more common.
Urinary system
Acute tubular necrosis (ATN) is a condition where the renal tubules are damaged by toxins or lack of oxygen, commonly caused by medications, contrast dyes, or liver/kidney diseases like diabetes. Blood urea nitrogen (BUN) and creatinine tests measure kidney function by detecting waste products that kidneys normally remove from the blood. Chronic renal failure involves a slow loss of kidney function over time which can lead to end-stage renal disease requiring dialysis or transplant if left untreated. Common causes are diabetes and high blood pressure. Intermittent peritoneal dialysis is a dialysis procedure used to correct fluid/electrolyte imbalances or remove waste when kidneys fail.

Posterior pitutary
The posterior pituitary gland, also called the neurohypophysis, contains nerve endings from the hypothalamus that secrete two hormones: oxytocin and antidiuretic hormone (ADH, also called vasopressin). These hormones are synthesized in the hypothalamus and transported to the posterior pituitary. ADH controls water conservation in the body by increasing water reabsorption in the kidneys. Oxytocin aids milk ejection from the breasts during nursing and helps stimulate contractions during childbirth. Both ADH and oxytocin secretion are stimulated by increased extracellular fluid osmolarity and decreased blood volume or pressure.
Oxytocin and vasopressin
This document summarizes oxytocin and vasopressin (antidiuretic hormone or ADH). It describes that oxytocin is secreted by the hypothalamus and posterior pituitary and acts on mammary glands to cause milk ejection and on the uterus to facilitate birth and transport of sperm. ADH is also secreted by the hypothalamus and pituitary and has two main actions - retaining water in the kidneys by increasing water reabsorption and vasoconstriction. Conditions of inappropriate hypersecretion and hyposecretion of each hormone are also summarized.
Endocrine disorder
The pituitary gland, also known as the hypophysis, acts as the control center for the endocrine system. It has an anterior and posterior lobe. The anterior lobe is controlled by hormones from the hypothalamus that stimulate or inhibit the release of hormones like growth hormone, thyroid stimulating hormone, and adrenocorticotropic hormone. These hormones target organs like the thyroid, adrenals, and liver. The posterior lobe stores and releases oxytocin and antidiuretic hormone which are produced in the hypothalamus. Pituitary tumors can cause hyperpituitarism by overproducing hormones or compressing the pituitary and decreasing hormone production.

Endocrine basic and advanced by dr ashvini jakhar
The endocrine system consists of glands that secrete hormones directly into the bloodstream to regulate distant target organs and tissues. The pituitary gland is called the "master gland" as it controls other endocrine glands by producing hormones that stimulate or inhibit their secretions. Disorders of the endocrine system can result from too little or too much hormone production and can have wide-ranging effects on the body if left untreated.
Endocrine System

Anatomy and physiology of endocrine system by Simhachalam K L V
The endocrine system is comprised of glands that secrete hormones directly into the bloodstream to regulate functions in target organs. The major endocrine glands include the hypothalamus, pituitary gland, pineal gland, thyroid gland, parathyroid glands, thymus gland, adrenal glands, pancreas, ovaries, and testes. Hormones control metabolism, growth and development, reproduction, and the body's response to stress. Imbalances in hormone levels can lead to disorders that may be treated by controlling hormone production or utilization.
Reproductive system
This document summarizes the male and female reproductive systems. It describes the pathway of sperm from the testes through the epididymis, ductus deferens, and urethra. It also outlines the accessory organs that contribute to semen production like the seminal vesicles and prostate gland. For the female, it discusses egg production in the ovaries and their monthly release, as well as the structure and hormonal control of the uterus and ovaries. Key parts of both systems and their functions are defined.
Posterior pituitary
Posterior Pituitary or Neurohypophysis composed mainly of glial-like cells called pituicytes.
The pituicytes do not secrete hormones.
They act simply as a supporting structure for large numbers
of terminal nerve fibers and terminal nerve endings from nerve tracts.
That originate in the supraoptic and paraventricular
nuclei of the hypothalamus.
ENDOCRINE SYSTEM.pptx
The endocrine system regulates whole body function through hormones. Hormones are released by endocrine glands and circulate through the bloodstream to target sites. Key endocrine glands include the hypothalamus, pituitary, thyroid, parathyroid, adrenals, pancreas, ovaries/testes. The pituitary gland regulates other glands through releasing hormones like TSH, FSH, LH, ACTH, and GH. Thyroid hormones T3 and T4 regulate metabolism, and calcitonin regulates calcium levels. The parathyroid secretes PTH which increases calcium absorption and resorption from bones.
THE-ENDOCRINE-SYSTEM-ppt.pptx
The endocrine system is made up of glands that produce hormones, which are chemical messengers that influence cells and organs throughout the body. There are four principal ways cells communicate: gap junctions, neurotransmitters, paracrines, and hormones. The pituitary gland located in the brain secretes several important hormones including follicle-stimulating hormone, luteinizing hormone, thyroid-stimulating hormone, adrenocorticotropic hormone, prolactin, and growth hormone from its anterior lobe. Its posterior lobe secretes antidiuretic hormone and oxytocin. Other endocrine glands include the pineal gland, thyroid gland, pancreas, ovaries, testes, and adrenal glands.

Nervous tissue 1
Neural tissue conducts electrical impulses and transmits signals between the central nervous system and other body structures. It develops through processes like cell proliferation, differentiation, migration, and outgrowth of neuronal processes. Neural tissue contains neurons, which generate and transmit nerve impulses, and neuroglia, which support and protect neurons. Neurons have a cell body, dendrites that receive signals, and an axon that conducts signals away from the cell body. Neuroglia include astrocytes, oligodendrocytes, ependymal cells, and microglia. Myelinated axons allow for faster signal conduction than unmyelinated axons.
Ovarian cycle
The document discusses several topics related to human reproductive cycles:
1. The ovarian cycle consists of the follicular and luteal phases, culminating in ovulation in the middle. The corpus luteum forms during the luteal phase and secretes hormones to prepare the uterus.
2. The menstrual cycle is controlled by ovarian hormones and has proliferative, secretory, and menstrual phases that regulate the endometrium.
3. Placentation begins with implantation and involves the formation of chorionic villi from the embryo and decidua from the endometrium to facilitate nutrient/waste exchange between mother and fetus without blood mixing. The placenta secretes important hormones throughout pregnancy.
Female Histology
The document describes the key parts of the female reproductive system including internal organs like the ovaries, oviducts, uterus, and vagina as well as external genitalia. It provides details on the ovaries and ovarian follicles, discussing their development from primordial to secondary to graafian follicles. It explains ovulation, the formation and role of the corpus luteum, and the ovarian and hormonal cycles. Key points are summarized around follicular development and atresia, ovulation, the corpus luteum, and the oviduct's role in transporting the ovum and embryo.

.rheumat
Rheumatic fever is an inflammatory disease caused by a prior streptococcal infection. It can cause heart valve damage and other issues. The disease is characterized by migratory arthritis, heart involvement including valvular lesions, subcutaneous nodules, erythema marginatum, and Sydenham's chorea. The pathogenesis involves molecular mimicry where antibodies to streptococcus cross react with human tissues like heart valves. Diagnosis is based on Jones criteria of major and minor symptoms. Prevention relies on proper antibiotic treatment of streptococcal infections. Congenital heart defects can cause left to right or right to left shunts depending on the specific defect. Common defects include ventricular septal defects, atrial septal defects,
