This document discusses hormones and the endocrine system. It provides information on various hormones produced by different endocrine glands and their target organs and functions. Specifically, it discusses hormones produced by the hypothalamus and pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, and gonads. It also discusses the target concept of hormone action and provides a table outlining various hormones, their sources, targets, and principal actions.
The document discusses various hormones in the endocrine system, including those produced by glands like the pancreas, thyroid, and gonads. It provides information on hormones like insulin, glucagon, estrogen, progesterone, and testosterone, and describes their roles and target organs. Graphs are included showing the relationships between hormones produced in the hypothalamus and pituitary gland and their effects on other endocrine glands.
The nervous and endocrine systems work together to monitor and regulate cells in the body. The endocrine system uses hormones to initiate responses in target cells by binding to specific receptors. Hormones are classified by their structure and function, with some made from cholesterol and others from amino acids. Hormones are released into the bloodstream and bind with matching receptors on target cells to initiate various responses and maintain homeostasis. The major endocrine glands and their hormones are the pituitary, thyroid, parathyroid, adrenal, pancreas, gonads, placenta and pineal glands.
This document summarizes the functions of gonads and sex hormones in males and females. It explains that in males, the testes produce testosterone, which stimulates male sex characteristics and sexual drive. In females, the ovaries produce estrogens and progesterone. Estrogens regulate the menstrual cycle and develop female sex characteristics, while progesterone prepares the uterus for pregnancy and mammary glands for lactation. Both the testes and ovaries secrete inhibin to regulate follicle-stimulating hormone levels.
As a component of the endocrine system, both male and female gonads produce sex hormones. Male and female sex hormones are steroid hormones and as such, can pass through the cell membrane of their target cells to influence gene expression within cells. Gonadal hormone production is regulated by hormones secreted by the anterior pituitary in the brain. Hormones that stimulate the gonads to produce sex hormones are known as gonadotropins. The pituitary secretes the gonadotropins luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These protein hormones influence reproductive organs in various ways. LH stimulates the testes to secrete the sex hormone testosterone and the ovaries to secrete progesterone and estrogens. FSH aids in the maturation of ovarian follicles (sacs containing ova) in females and sperm production in males.
The male reproductive system is regulated by the hypothalamic-pituitary-testicular axis. The hypothalamus produces GnRH which stimulates the pituitary gland to secrete LH and FSH. LH acts on the testes to stimulate production of testosterone, while FSH supports sperm production. Testosterone promotes male secondary sex characteristics and regulates its own production through negative feedback on the hypothalamus and pituitary. Precise control of these hormones is vital for normal male development, sexual function, and fertility.
The endocrine and nervous systems work together to maintain stability in the body. The endocrine system is slower acting and releases hormones into the bloodstream to target cells, while the nervous system sends rapid impulses through nerves. Major endocrine glands include the hypothalamus, pituitary, thyroid, parathyroid, adrenal, pancreas, ovaries/testes, and placenta. Hormones bind to receptors on target cells and regulate various bodily functions like growth, metabolism, fluid balance, reproduction, and mood.
This document summarizes hormones and their roles in reproduction. It discusses:
- The classifications of reproductive hormones based on mode of action (primary vs secondary) and biochemical structure (proteins, steroids, etc).
- The primary hormones of reproduction (FSH, LH) and how they regulate processes like spermatogenesis and ovulation.
- Other reproductive hormones like estrogen, progesterone, testosterone, and how they act in males and females.
- The hypothalamic-pituitary-gonadal feedback mechanisms that regulate hormone secretion.
- Placental hormones involved in pregnancy like hCG and placental lactogen.

Presented by Zeleke Mekuriaw at the EIAR-DBARC-ICARDA-ILRI (LIVES)-FAO Training Workshop on Reproduction in Sheep and Goat, Debre Berhan, Ethiopia, 13-15 October 2014
The document discusses the endocrine and nervous systems. It provides information on 16 different endocrine glands and their hormone productions. Key endocrine glands discussed include the pituitary gland, thyroid gland, parathyroid gland, adrenal gland, pancreas, testes, ovaries, placenta, thymus, and heart. The endocrine system works through chemical messengers called hormones to help regulate processes in the body like growth, metabolism, sexual function, stress response, and fluid balance. The nervous system works faster than the endocrine system through nerve impulses to control behaviors and homeostasis.
The endocrine system consists of glands that produce hormones, chemical messengers released into the bloodstream. Hormones cause slow, long-term, and often irreversible changes related to growth and reproduction. Key glands include the pituitary, thyroid, pancreas, adrenals, ovaries, and testes, each releasing important hormones like growth hormone, thyroxine, insulin, estrogen, progesterone, and testosterone. The endocrine system differs from the nervous system in using chemical signals instead of electrical ones, causing generally slower but often irreversible changes throughout the body.

The growth hormone is produced by somatotropes cells in the anterior pituitary gland. Its release is regulated by growth hormone releasing hormone and growth hormone release inhibiting hormone from the hypothalamus. Growth hormone promotes growth and influences metabolism. Deficiencies cause dwarfism while overproduction causes gigantism or acromegaly. The gonads produce sex hormones and germ cells. Androgens are produced in males and influence physiological functions and metabolism. Estrogens are predominantly ovarian hormones and influence the menstrual cycle and female development. Progesterone is required for pregnancy and influences the uterus and mammary glands.
The endocrine system is made up of glands that secrete hormones directly into the bloodstream to regulate bodily functions. Major glands include the pituitary, thyroid, parathyroid, adrenal, pancreas, ovaries, testes, and pineal gland. Hormones control processes like metabolism, growth and development, tissue function, sleep cycles, mood, and reproduction.
This document discusses how hormones act as mediators in development. It describes how hormones secreted by glands like the pituitary, thyroid, and sex organs play an important role in growth. The pituitary gland secretes growth hormone and controls other glands. Thyroid hormone is necessary for normal growth and brain development. Sex hormones like testosterone and estrogens influence sexual development and characteristics during puberty. The brain controls the pituitary and the timing of sexual maturity.
The document discusses the endocrine system and hormones. It provides information on various endocrine glands like the pituitary, thyroid, parathyroid, adrenal, pancreas, gonads, placenta, thymus, and mucosa. It explains the functions of hormones, how they are classified as steroid or nonsteroid, and how hormones interact with receptors in target cells. The roles of various hormones such as melatonin, growth hormone, insulin, estrogen and testosterone are outlined.
The document discusses the relationship between hormones and behavior in animals. It explains that hormones secreted from endocrine glands influence moods and responses to stimuli. Animal reproductive and maternal behaviors are regulated seasonally based on changing hormone levels, such as increases in sex hormones during breeding seasons. Specific hormones like progesterone, prolactin, LH, and melatonin influence behaviors related to incubation, feeding of young, ovulation, and growth of reproductive organs. Hormones also affect aggressive behaviors, territorial markings, and development of sexual characteristics. Behaviors are regulated through the interactions of the pituitary gland, gonads, and adrenal systems.
The document summarizes the major endocrine glands and hormones in the human body. It describes that the hypothalamus and pituitary gland (hypophysis) are important master glands that regulate other endocrine glands. The pituitary gland is divided into the anterior, middle (medulla), and posterior lobes. The anterior and middle lobes produce hormones that regulate other glands like the thyroid, adrenals, ovaries and testes. The thyroid produces thyroxine and triiodothyronine which regulate metabolism. Other major glands discussed are the parathyroids, pancreas, ovaries, testes, adrenals and placenta.
The endocrine system is made up of glands that secrete hormones directly into the bloodstream to regulate distant target cells and tissues. The major endocrine glands include the pituitary, thyroid, parathyroid, adrenal, pancreas and reproductive organs. Hormones communicate with target cells through membrane receptors or nuclear receptors and can influence cells even at low concentrations. Negative feedback loops precisely control hormone secretion levels. The pituitary gland regulates other endocrine glands through releasing hormones and regulates body processes like growth, milk production, metabolism and reproduction.
The endocrine system is composed of organs positioned throughout the body in widely separated locations. Endocrinology is the study of the structure and functioning of the endocrine system.

Hormones in human body , biological bases of behavior Anand Choudhary
This document provides an overview of hormones and their functions. It describes hormones as chemicals secreted by endocrine glands that influence other glands and organs. There are two major classes of hormones - protein hormones like insulin and glucagon, and steroid hormones derived from cholesterol like corticoids and sex steroids. The release of hormones is controlled by the hypothalamus and pituitary gland using negative feedback systems. Specific hormonal disorders that impact sexual development and characteristics are also discussed, as well as the effects of pheromones on behavior in animals and humans.
GnRH is a peptide hormone released from the hypothalamus that stimulates the release of FSH and LH from the pituitary gland. In fish, GnRH is expressed early in development as neurons migrate and form populations in the brain. GnRH mRNA and peptide have also been found in fish gonads, suggesting a potential paracrine role, though the exact role is unclear. GnRH receptors have been identified in the gonads of several fish species. GnRH has been shown to stimulate meiosis in fish oocytes and affect behaviors like territoriality in some fish. Further research is still needed to fully understand GnRH function in fish.

The document provides an in-depth look at the endocrine system through recipes and tables. It discusses how the nervous and endocrine systems work together to regulate hormones. The major glands of the endocrine system are described, including the hypothalamus, pituitary gland, thyroid gland, parathyroid gland, adrenal gland, pineal body, and reproductive glands. Hormones are classified by function and structure. Steroid and nonsteroid hormones are defined. Finally, tables list the major hormones and the glands, targets, and principal actions of each.
The document discusses various hormones produced by the pituitary gland and hypothalamus, including growth hormone, thyroid-stimulating hormone, adrenocorticotropic hormone, follicle-stimulating hormone, luteinizing hormone, prolactin, oxytocin, and antidiuretic hormone. It describes the targets and functions of these hormones in regulating processes like growth, metabolism, reproduction, lactation, water balance, and stress response. The hormones act through feedback loops between the hypothalamus and pituitary to control hormone release from other endocrine glands.
FSH, LH, and testosterone are hormones that regulate reproductive functions. FSH acts on the ovaries and testes to stimulate gamete production. LH triggers ovulation in females and supports testosterone production in males. Testosterone promotes male sexual development and secondary sex characteristics. The hormones work by binding to receptors on target cells and activating intracellular signaling cascades. Abnormal levels can cause diseases like polycystic ovarian syndrome or Klinefelter syndrome.
The document summarizes key information about endocrine glands and their hormones. It discusses that endocrine glands are groups of secretory cells that release hormones directly into the bloodstream. The major endocrine glands include the hypothalamus, pituitary gland, thyroid gland, parathyroid gland, adrenal gland, ovaries, testes, pancreas and pineal gland. Each gland secretes specific hormones that target distant tissues, regulating processes like growth, metabolism, reproduction and homeostasis. Hormone secretion is regulated by negative feedback loops between the hypothalamus and pituitary gland.

The role of hormones in the female and male reproductive systems is also summarized, including how hormones like FSH and LH control the menstrual cycle and sperm production. Finally, common endocrine disorders are briefly described, such as osteoporosis, goiter, gigantism and dwarfism resulting from hormonal im
The endocrine system consists of glands that secrete hormones directly into the bloodstream to regulate distant target organs and tissues. The major glands include the pituitary, thyroid, parathyroid, adrenal, pancreas, ovaries, and testes. The pituitary gland is considered the "master gland" as it controls other endocrine glands by producing hormones that stimulate or inhibit their secretions. Hormones travel through the bloodstream to target cells, regulating critical functions like growth, metabolism, mood, fertility, and fluid and mineral balance. Negative feedback loops help maintain optimal hormone levels within a narrow range.
The anterior pituitary gland, also called the adenohypophysis, is divided into two parts: the pars anterior and the tiny pars intermedia. The pars anterior contains five major cell types that secrete different hormones: somatotrophs secrete growth hormone, corticotrophs secrete ACTH, thyrotrophs secrete TSH, lactotrophs secrete prolactin, and gonadotrophs secrete LH and FSH. The hypothalamus controls hormone secretion in the anterior pituitary through releasing and inhibiting hormones that travel via the hypophyseal portal system and stimulate or suppress hormone production.
The document summarizes key aspects of the human endocrine system. It describes the main endocrine glands including the hypothalamus, pituitary gland, thyroid gland, parathyroid gland, pineal gland, thymus gland, adrenal gland and pancreas. It provides details on the hormones produced by each gland and their functions in regulating processes like growth, metabolism, sexual development and the immune system. The hypothalamus and pituitary gland play central roles in controlling the other endocrine glands through releasing and inhibiting hormones.
The document summarizes key aspects of the female reproductive system and endocrinology. It discusses the female phenotype and sex hormones like estrogen, progesterone, FSH and LH. It describes the hypothalamic-pituitary-ovarian axis and how hormones regulate the menstrual cycle and reproduction. Other endocrine glands like the thyroid and their roles in fertility are also mentioned.
The endocrine system regulates homeostasis, growth, development, reproduction and other processes through the secretion of hormones like peptides, steroids, and amines. Hormones are synthesized in endocrine glands like the pituitary, thyroid, adrenals, gonads and pancreas, then secreted into the bloodstream and delivered to target tissues. There, they produce physiological responses through feedback loops to maintain appropriate hormone levels.
The document summarizes the structure and function of the anterior pituitary gland and its relationship to the hypothalamus. It discusses the following key points:
- The anterior pituitary secretes 6 hormones (GH, ACTH, TSH, Prolactin, FSH, LH) which control various target glands and metabolic functions.
- The hypothalamus controls anterior pituitary secretion through releasing and inhibitory hormones transported via a portal system. These include TRH, GnRH, CRH, GHRH, and dopamine.
- Disorders of the anterior pituitary can cause gigantism/acromegaly from hypersecretion or dwarfism from hyposecretion of growth hormone.
The endocrine system controls physiological processes through the secretion of hormones into the bloodstream. Hormones are either steroid hormones which diffuse through cell membranes or nonsteroid hormones which bind to cell surface receptors. Hormone actions are regulated by negative feedback loops and the number of receptors on cells. The major endocrine glands include the pituitary, thyroid, parathyroid, adrenal, pancreas, and gonads, each secreting hormones that regulate processes like metabolism, growth, and reproduction. During exercise, hormones like glucagon, epinephrine, and growth hormone are released to increase glucose availability and mobilize energy stores.
General introduction and pituitary gland Secretion, Function and RegulationSELINA SRAVANTHI
The endocrine system regulates bodily functions through hormones secreted into the bloodstream. The hypothalamus and pituitary gland act as the master glands of the endocrine system. The pituitary gland secretes hormones that control other endocrine glands and is regulated by hormones from the hypothalamus. The major hormones secreted by the pituitary include growth hormone, thyroid stimulating hormone, follicle stimulating hormone, luteinizing hormone, prolactin, and adrenocorticotropic hormone. These hormones regulate functions such as growth, metabolism, reproduction and stress response.

The endocrine system consists of glands that secrete hormones directly into the bloodstream to regulate physiological and biological functions throughout the body. Major endocrine glands include the pituitary, thyroid, parathyroid, adrenals, pancreas, ovaries, and testes. Hormones maintain homeostasis, control growth and development, regulate metabolism and physical activity, and influence reproductive processes and biological rhythms. Target cells contain receptors that allow hormones to have remote effects on various bodily systems and adapt organisms to environmental changes.
Neuroendocrinal regulation of menstrual cycleAman Baloch
This document discusses the neuroendocrine regulation of the menstrual cycle. It begins by explaining that the regulation is a complex, genetically determined system involving the genitals, central nervous system, and target organs. It then describes the 5 levels of regulation: 1) target organs, 2) ovaries, 3) hypophysis (pituitary gland), 4) hypothalamus, and 5) extra-hypothalamic structures. The roles of estrogen, progesterone, androgen, FSH, LH, and other hormones are explained. The document also covers ovarian and uterine cycles, menstrual disorders including amenorrhea, and their potential etiologies.
The endocrine system is a messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In vertebrates, the hypothalamus is the neural control center for all endocrine systems.
This document summarizes the endocrine system, including its glands and hormones. The hypothalamus and pituitary gland secrete hormones that signal other endocrine glands. The hypothalamus releases hormones that control the pituitary, which in turn secretes hormones regulating thyroid, adrenal, and reproductive functions. Other glands like the pineal body and thyroid also communicate via hormones. The endocrine system maintains homeostasis through chemical messengers called hormones.
