What are the target organs of Oestrogen?
Estrogens have multiple effects on the growth and development of cells in their target tissues, including the uterus, ovary, breast, bone marrow and brain. The hormone regulates the transcription of diverse genes in these tissues via the estrogen receptor, a nuclear transcription factor.
What is the target organ of a hormone?
The anterior pituitary hormones enter the systemic circulation and bind to their receptors on other target organs. In the case of TSH, the target organ is the thyroid gland….Overview of Hypothalamic and Pituitary Hormones.
| Anterior Pituitary | |
| Hormone | Prolactin |
| Major target organ(s) | Mammary gland |
| Major Physiologic Effects | Milk production |
What is the target organ?
Definition: The biological organ(s) most adversely affected by exposure to a chemical substance.
What are the 2 target organs for growth hormone?
Growth hormone (GH), also called somatotropin or human growth hormone, peptide hormone secreted by the anterior lobe of the pituitary gland. It stimulates the growth of essentially all tissues of the body, including bone.
What are the target organs of ovaries?
| Gland | Hormone gland releases | Target organ |
|---|---|---|
| Ovaries | Oestrogen | Uterus |
| Ovaries | Progesterone | Uterus |
| Pituitary | FSH (Follicle stimulating hormone) | Ovaries |
| Pituitary | LH (Luteinising hormone) | Ovaries |
What is cortisol’s target organ?
Cortisol works on target tissues to increase blood glucose levels. It does this by aiding the metabolism of carbohydrate reserves from the liver as well as breaking down fat and protein to help provide quick bursts of energy.
What is a target organ example?
Target organs include the bone marrow, skin, and nervous system after either acute or chronic excessive exposure.
What is a target organ effect?
Indicates which bodily organs are most likely to be affected by exposure to a substance.
Where does progesterone come from in the female reproductive system?
Progesterone, hormone secreted by the female reproductive system that functions mainly to regulate the condition of the inner lining (endometrium) of the uterus. Progesterone is produced by the ovaries, placenta, and adrenal glands.
Which is the target organ of gonadotropin releasing hormone?
What is the target organ of GnRH? Gonadotropin Releasing Hormone (GnRH) In the male and the female, the target tissue is the anterior pituitary gland, specifically Gonadotroph cells. In males and females, secretion of GnRH results in the release of Follicle Stimulating Hormone (FSH) and Leutinising Hormone (LH) from the anterior pituitary gland.
What is the function of progesterone in the brain?
Progesterone binds to brain cell receptors and metabolizes allopregnanolone in brain tissues, producing calming, anti-anxiety, and possible memory-enhancing effects. The hormone also protects the brain from damage and promotes repair after injury by encouraging the growth and repair of the myelin sheath that protects the nerve fibers.
Which is the target tissue for growth hormone?
TARGET TISSUE. FUNCTION. Adrenocorticotropic. Pituitary gland (anterior) Adrenal cortex. Triggers secretion of hydrocortisone from the adrenal gland. Growth hormone. Pituitary gland (anterior)
