What does the Gonadotropic hormone do?
Gonadotropins are any hormones that stimulate the gonads, or sex glands, to carry out their reproductive or endocrine functions. In males, these glands are the testes, and in females the ovaries.
What is the target organ of gonadotropin?
Gonadotropins are released under the control of gonadotropin-releasing hormone (GnRH) from the arcuate nucleus and preoptic area of the hypothalamus. The gonads — testes and ovaries — are the primary target organs for LH and FSH.
What is the target tissue of gonadotropin-releasing hormone?
Although hypothalamus and pituitary are the principal source and target sites for GnRH, several reports have recently suggested extra-hypothalamic GnRH and GnRH receptors in various reproductive tissues such as ovaries, placenta, endometrium, oviducts, testes, prostrate, and mammary glands.
What are the target organs of the pituitary hormones?
Overview of Hypothalamic and Pituitary Hormones
| Hormone | Major target organ(s) | |
|---|---|---|
| Anterior Pituitary | Growth hormone | Liver, adipose tissue |
| Thyroid-stimulating hormone | Thyroid gland | |
| Adrenocorticotropic hormone | Adrenal gland (cortex) | |
| Prolactin | Mammary gland |
Which is a function of the Gonadotropic hormones quizlet?
Gonadotropin Hormone stimulates Testosterone in Males. Which organ within the body regulates Gonadotropin Hormones (FSH and LH) within the body?
What are target organs?
n. A tissue or organ that is affected by a specific hormone.
What organ produces the gonadotropin releasing hormone or GnRH?
hypothalamus
Gonadotrophin-releasing hormone is produced and secreted by specialised nerve cells in the hypothalamus of the brain.
What are the target organs of hormones?
| Endocrine gland/ source of hormone | Hormone | Target organ or tissue |
|---|---|---|
| Anterior pituitary (adenohypophysis) | ACTH (adrenocorticotrophic hormone) | Adrenal cortex |
| FSH (follicle stimulating hormone) | Ovaries / testes (tubules) | |
| LH (luteinizing hormone) | Ovaries / testes (Leydig cells) | |
| GH (growth hormone) | All tissues |
What is the purpose of luteinizing hormone LH in males quizlet?
LH triggers the Leydig cells of the testes to produce and secrete testosterone, which is essentially needed for sperm production.
Which hormones stimulates the breakdown of polymerized glucose?
The pancreas releases glucagon, which eventually causes blood glucose levels to increase. The pancreas releases insulin, which eventually causes blood glucose levels to increase. The pancreas releases glucagon, which eventually causes blood glucose levels to decrease.
Where are gonadotropins released in the human body?
Gonadotropins are released under the control of gonadotropin-releasing hormone (GnRH) from the arcuate nucleus and preoptic area of the hypothalamus. The gonads — testes and ovaries — are the primary target organs for LH and FSH.
Where are the gonadotropes located in the pituitary?
Gonadotropes in the Normal Pituitary. They produce the gonadotropins, follicle-stimulating hormone (FSH), and luteinizing hormone (LH). They are scattered throughout the pars distalis, or anterior pituitary, where they constitute approximately 10% of adenohypophysial cells in adult human pituitaries.
What kind of function do gonadotropins have in the ovaries?
They act on the maturation and function of the ovaries and testes. Gonadotropins include FSH and LH, both of which are glycoproteins. FSH (∼34 kDa) contains 10% carbohydrates, while LH (∼25 kDa) has 15% carbohydrates. The hydrocarbon chains of both gonadotropins have mannose, galactose, fucose, glucosamine, galactosamine, and sialic acid.
Where does the gonadotropin LH and FSH come from?
LH and FSH are secreted by the anterior pituitary gland, while hCG and eCG are secreted by the placenta in pregnant humans and mares, respectively. The gonadotropins act on the gonads, controlling gamete and sex hormone production. Gonadotropin is sometimes abbreviated Gn.
