Question

the hypothalamus controls excretions from the pituitary gland. it causes the release of some hormones from the pituitary by direct nervous control, and others by secreting releasing and inhibiting factors that stimulate the pituitary to secrete hormones. which best describes the hypothalamus? it is a connection point between the nervous and endocrine systems. it is both an exocrine and endocrine gland. it is referred to as the \master gland.\ it secretes its contents into ducts.

Explanation:

The hypothalamus controls the pituitary gland through nervous control and by secreting factors. The nervous system aspect (direct nervous control) and the endocrine system aspect (secreting factors to influence hormone release in the pituitary, which is an endocrine gland) show its role as a connection. An exocrine gland secretes into ducts (not the case here), the pituitary is the “master gland” (not the hypothalamus), and there's no mention of duct - related secretion for the hypothalamus in the given text.

Answer:

It is a connection point between the nervous and endocrine systems.
