Which anterior pituitary hormones are tropic?

Tropic hormones from the anterior pituitary include: Thyroid-stimulating hormone (TSH or thyrotropin) – stimulates the thyroid gland to make and release thyroid hormone. Adrenocorticotropic hormone (ACTH or corticotropin) – stimulates the adrenal cortex to release glucocorticoids.

Which four of the anterior pituitary hormones are tropic hormones?

When we look at hormones that have other endocrine glands as their target, we call them tropic hormones. The four tropic hormones of the anterior pituitary gland are: follicle-stimulating hormone (FSH), luteinizing hormone (LH), adrenocorticotropic hormone (ACTH), and thyroid-stimulating hormone (TSH).

What hormones are tropic?

The tropic hormones include thyroid-stimulating hormone, corticotropin, follicle-stimulating hormone, and luteinizing hormone.

How many trophic hormones does the anterior pituitary produce?

The cells within this lobe are responsible for the synthesis of at least six major hormones: growth hormone (GH), prolactin (PRL) or luteotropic hormone (LTH) and adrenocorticotropin (ACTH), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and thyroid-stimulating hormone (TSH) or thyrotropin.

What anterior pituitary hormone is not a tropic hormone?

Lastly, cortisol (non-tropic) is secreted from the adrenal glands and goes into the bloodstream where it can have more widespread effects on organs and tissues. Since cortisol is what finally reaches other tissues in the body, it is a non-tropic hormone.

What are the 7 hormones of the anterior pituitary gland?

The anterior pituitary gland secretes 7 hormones: follicle -stimulating hormone, luteinizing horomone, adrenocorticotropic horomone, thyroid -stimulating horomone, prolactin, endorphins, and growth hormone.

What are the 4 types of hormones?


  • libid-derived hormones.
  • amino acid-derived hormones.
  • peptide hormones.
  • glycoprotien hormones.

Can a hormone be both tropic and trophic?

Most tropic hormones are produced and secreted by the anterior pituitary. … This should not be confused with trophic, as in similar-sounding trophic hormone – the words and concepts are both unrelated. Tropic hormones are contrasted with non-tropic hormones, which directly stimulate target cells.

Is MSH a tropic hormone?

vertebrates produce essentially the same tropic hormones: thyrotropin (TSH), corticotropin (ACTH), melanotropin (MSH), prolactin (PRL), growth hormone (GH), and one or two gonadotropins (usually FSH-like and LH-like hormones).

Why growth hormone is called a trophic hormone?

Trophic hormones are hormones of the anterior lobe of the pituitary. These hormones affect growth, function, or nutrition of other endocrine cells. … Adrenocorticotropic hormone (ACTH or corticotropin) – stimulates the adrenal cortex increasing the size and number of cells.

What is the target organ of pituitary gland?

Endocrine gland/ source of hormone Hormone Target organ or tissue
Hypothalamus Numerous releasing factors Pituitary gland
Anterior pituitary (adenohypophysis) ACTH (adrenocorticotrophic hormone) Adrenal cortex
FSH (follicle stimulating hormone) Ovaries / testes (tubules)
LH (luteinizing hormone) Ovaries / testes (Leydig cells)

What triggers the release of anterior pituitary hormones?

For example, the anterior pituitary lobe will release adrenocorticotropic hormone (ACTH) to stimulate cortisol production in the adrenal glands when you’re stressed. The anterior lobe releases hormones upon receiving releasing or inhibiting hormones from the hypothalamus.

Which is not a trophic hormone?

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.

Why is gh not a tropic hormone?

Endocrine System : Example Question #2

What aspect of growth hormone differentiates it from other anterior pituitary hormones? Explanation: Non-tropic hormones are hormones that directly stimulate target cells to induce effects. … Growth hormone (GH) stimulates growth through both tropic and non-tropic mechanisms.

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

Why is the anterior pituitary called the master gland?

Anatomy of the pituitary gland

The pituitary gland is sometimes called the “master” gland of the endocrine system because it controls the functions of many of the other endocrine glands.
