Q: Which part of the brain secretes hormones that tell the pituitary gland either to secrete or to stop secreting its hormones?


Read this paragraph and choose the correct option from the provided answers:

The hypothalamus is actually part of the brain (see Figure below ), but it also secretes hormones . Some of its hormones “tell” the pituitary gland either to secrete or to stop secreting its hormones. In this way, the hypothalamus provides a link between the nervous and endocrine systems. The hypothalamus also produces hormones that directly regulate body processes. These hormones travel to the pituitary gland, which stores them until they are needed. The hormones include antidiuretic hormone and oxytocin.

 Choices:

- cerebrum

- hippocampus

- thalamus

- hypothalamus


A:
hypothalamus
