Name any five peptide hormones secreted by the pars distalis of the adenohypophysis and the cell types from which they are secreted

Expert Solution

Pars distalis is a part of pituitary gland.

Pituitary gland is an endocrine gland and has two parts which are anterior pituitary and posterior pituitary .

Anterior pituitary also called adenohypophysis has 3 parts

a)pars tuberalis

b)pars intermedia

c)pars distalis

Posterior pituitary also called neurohypophysis has

a)infundibular stalk

b)pars nervosa

Pars distalis has 2 types of cells

a)chromophobe cells -50 %

b)chromophil cells -50%

Chromophil cells include acidophils 40% and basophils-10%

Acidophils include somatotrope and lactotrope .

Basophils include thyrotrope ,gonadotrope ,cortocotrope.

Peptide harmones secreted by pars distalis are

1.GH(growth hormone)- by somatotrope

2.prolactin - by lactotrope

3.TSH(thyroid stimulating hormone)-by thyrotrope

4.FSH(follicle stimulating hormone)- by gonadotrope

5.LH(luteinizing hormone)-by gonadotrope

6.ACTH(adrenocorticotropic homone)- by cortocotrope.

The hormone atrial natriuretic peptide is secreted by the atria to regulate blood pressure in a homeostatic fashion .A. Atrial natriuretic peptide inhibits the secretion of renin and aldosterone. How would this peptide affect blood volume and blood pressure? B. Atrial natriuretic peptide also acts to dilate blood vessels. What effect will dilating blood vessels have on blood velocity and blood pressure? C. The body secretes atrial natriuretic peptide in response to a certain physical signal from the atria. What...

Of the hormones secreted by the posterior pituitary, if you had to choice one to be in a "hypo" state which one would it be and why? What are the treatment options for this "hypo" state and what monitoring would need to be completed?

Which of the following is TRUE? Hormones are secreted into the blood in pulses by specific stimuli. Steroid hormones will bind to receptors located on the cell membrane. An example of a secondary messenger is estrogen, as it is released upon stimulation from a primary messenger, such as LH. Tyrosine kinase is located in the nucleus and causes new proteins to be created.
