Which is an accurate description of the posterior pituitary and its functions?
A)It is glandular tissue and secretes vasopressin and prolactin.
B)It is neural tissue and is stimulated to secrete oxytocin and vasopressin by hypophysiotropic hormones.
C)It is neural tissue,and vesicles containing oxytocin and vasopressin are transported to axon terminals there.
D)It is glandular tissue and releases oxytocin and somatostatin when action potentials arrive along axons from the hypothalamus.
E)It is neural tissue that secretes hypophysiotropic hormones that control the secretion of the anterior pituitary hormones.

Quizplus · Accepted Answer

The posterior pituitary is composed of neural tissue and does not actually synthesize any hormones; instead, vesicles containing oxytocin and vasopressin are transported to axon terminals in the posterior pituitary where they are released in response to neural stimulation from the hypothalamus. Therefore, option C is the accurate description of the posterior pituitary and its functions.
