Question

1) Which of the following is FALSE regarding secretion of hormones from the hypothalamus and pituitary glands?

Anterior pituitary tropic hormones cause release of hormones from another primary endocrine organ.

2) Which of the following is an example of long loop negative feedback?

Excess thyroid hormone leads to a decreased release of thyroid stimulating hormone (TSH).

3)Which pancreatic cell type secretes glucagon?

alpha cells

4)Gastrin, cholecystokinin (CCK), and glucose-dependent insulinotropic peptide (GIP) are all hormones secreted by __________.

5)An elderly man has been evaluated by a physician and told that he has a secondary hyposecretion disorder of the parathyroid glands. What sign or symptom might this patient display?

Hypothalamic tropic hormones are neurohormones. Anterior pituitary tropic hormones are secreted from endocrine cells, not neurons. The portal vein supplies both the anterior and posterior pituitary glands with blood.

Anterior pituitary tropic hormones cause release of hormones from another primary endocrine organ.

2) Which of the following is an example of long loop negative feedback?

Excess growth hormone inhibiting hormone (GHIH) leads to decreased growth hormone (GH) secretion. Excess growth hormone (GH) leads to decreased secretion of growth hormone releasing hormone (GHRH). Excess adrenocorticotropic hormone (ACTH) leads to increased secretion of cortisol.

Excess thyroid hormone leads to a decreased release of thyroid stimulating hormone (TSH).

3)Which pancreatic cell type secretes glucagon?

delta cells beta cells gamma cells F cells

alpha cells

4)Gastrin, cholecystokinin (CCK), and glucose-dependent insulinotropic peptide (GIP) are all hormones secreted by __________.

secondary endocrine organs pituitary gland hypothalamus a primary endocrine organ

5)An elderly man has been evaluated by a physician and told that he has a secondary hyposecretion disorder of the parathyroid glands. What sign or symptom might this patient display?

decreased metabolism increased metabolism increased nerve excitability and muscle cramps decreased bone density

Explanation / Answer

1: C: The portal vein supplies anterior pituitary only while the posterior lobe gets arterial supply
2: B: Excess growth hormone (GH) leads to decreased secretion of growth hormone releasing hormone (GHRH) OR glucocorticoids inhibit the release of CRH
3: Alpha cells
4: secondary endocrine organs
5: Hyposecretion of parathyroid reduces the blood calcium level and causes increased nerve excitability and muscle cramps.
