Multiple Choice
The hypothalamus can release the hormone somatostatin, which ______.
A
inhibits the release of growth hormone from the anterior pituitary
B
promotes the release of prolactin from the anterior pituitary
C
increases blood glucose levels by promoting glycogen breakdown
D
stimulates the secretion of thyroid hormones
Verified step by step guidance
1
Understand the role of the hypothalamus in regulating hormone release. The hypothalamus is a key part of the endocrine system that controls the secretion of hormones from the pituitary gland.
Focus on somatostatin, which is a hormone released by the hypothalamus. Somatostatin is also known as growth hormone-inhibiting hormone (GHIH). Its primary function is to regulate the secretion of other hormones.
Analyze the options provided in the question. Somatostatin specifically inhibits the release of growth hormone (GH) from the anterior pituitary, which is its primary function.
Eliminate incorrect options by understanding their mechanisms. For example, somatostatin does not promote prolactin release, increase blood glucose levels, or stimulate thyroid hormone secretion. These functions are associated with other hormones.
Conclude that the correct answer is related to somatostatin's inhibitory effect on growth hormone release from the anterior pituitary, based on its physiological role.
