Which of the following statements best captures the relationship between the hypothalamus and the pituitary gland as it relates to endocrine function?
A)
The hypothalamus directly measures the levels of most hormones throughout the body and inhibits or stimulates the pituitary accordingly.
B)
The pituitary gland coordinates and dictates the release of hormones from the hypothalamus that act on their intended target cells.
C)
The pituitary gland and hypothalamus have two-way communication that mediates the signals from neuronal inputs.
D)
The hypothalamus receives input from numerous sources throughout the body and directs the pituitary to then control many target glands and cells.
Ans:
D
Feedback:
The hypothalamus can be viewed as a bridge by which signals from multiple systems are relayed to the pituitary gland. The hypothalamus collects data from sources throughout the body rather than directly measuring levels, and communication normally flows from the hypothalamus to the pituitary.
