What are the hypothalamic tropic hormones?
The hypothalamus secretes tropic hormones that target the anterior pituitary, and the thyroid gland secretes thyroxine, which targets the hypothalamus and therefore can be considered a tropic hormone. Tropic hormones are contrasted with non-tropic hormones, which directly stimulate target cells.
What are the 4 tropic hormones?
The pituitary cells that line the capillaries produce the tropic hormones: adrenocorticotropic hormone (ACTH), thyroid-stimulating hormone (TSH), growth hormone (GH), prolactin, and the gonadotropins luteinizing hormone (LH) and follicle-stimulating hormone (FSH) (see Figure 3–1).
What is an example of a tropic hormone?
tropic hormone (trophic hormone) any of a class of hormones from the anterior pituitary gland that affect the secretion of other endocrine glands. The tropic hormones include thyroid-stimulating hormone, corticotropin, follicle-stimulating hormone, and luteinizing hormone.
What is meant by trophic hormones?
Trophic hormones are hormones of the anterior lobe of the pituitary. These hormones affect growth, function, or nutrition of other endocrine cells. The term trophic is from Ancient Greekτροφικός (trophikós) meaning “pertaining to food or nourishment”, here used to mean “growth”; this is the same origin as atrophy.
What does a non-tropic hormone do?
Explanation: Non-tropic hormones are hormones that directly stimulate target cells to induce effects. For example, aldosterone acts directly on the kidney to promote reabsorption of sodium, which causes an increase in blood pressure.
Is insulin tropic or Nontropic?
| Tropic (or Pseudo-Tropic) Hormone(s) All are Peptides | Target Organ | Hormones/Secretions Made by Target Organ |
|---|---|---|
| TSH (thyroid stimulating H.) or Thyrotropin | Thyroid | Thyroxine* |
| GH (Growth H.) = somatotropin | Liver (& others) | Insulin-Like Growth Factors (ILGF 1 & 2) = somatomedins |
| Prolactin | Mammary Gland | Milk |
What are examples of antagonistic hormones?
Antagonistic hormones are a pair of hormones that have the opposite effects. For example, insulin and glucagon are antagonistic hormones because insulin functions to decrease blood glucose levels, whereas glucagon functions to increase blood glucose levels.
What is the difference between tropic and trophic hormones?
Tropic hormones are hormones that have other endocrine glands as their target. Most tropic hormones are produced and secreted by the anterior pituitary. But , Trophic hormone is a hormone that has a growth effect, hyperplasia or hypertrophy, on the tissue it is stimulating.
What is the difference between tropic and trophic hormone?
What kind of hormones are in the Tropic System?
Tropic hormones from the anterior pituitary include: 1 Thyroid-stimulating hormone (TSH or thyrotropin) – stimulates the thyroid gland to make…. 2 Adrenocorticotropic hormone (ACTH or corticotropin) – stimulates the adrenal cortex… 3 Luteinizing hormone (LH) – stimulates the release of steroid hormones in gonads —the ovary…
How does the hypothalamus regulate the endocrine system?
Somatostatin: This hormone is also known as Growth Hormone Inhibiting Hormone. It regulates the endocrine system and affects the neurotransmission and cell proliferation by interacting with G-protein coupled receptors. The middle region of hypothalamus stimulates the release of Growth Hormone Releasing Hormone.
What does the hypothalamus target?
The hypothalamus secretes tropic hormones that target the anterior pituitary, and the thyroid gland secretes thyroxine, which targets the hypothalamus and therefore can be considered a tropic hormone.
Are there any hormones from the anterior pituitary?
Tropic hormones from the anterior pituitary include: Thyroid-stimulating hormone (TSH or thyrotropin) – stimulates the thyroid gland to make and release thyroid hormone.
