Question

Charlize is walking across campus and hears a noise. When she looks up, she sees a tree branch heading straight for her. Immediately, the __________ in her nervous system sends a signal to the __________ in her endocrine system to release hormones and prepare her to move out of the way.

Answer 1

1. Hypothalamus

2. Pituitary gland

Step-by-step explanation:

Hypothalamus is a small region located in the lower portion in the brain which controls the body functions by releasing the factors.

The hypothalamus secretes molecules which act on the pituitary gland which produces hormones. These hormones bind to the target site and control the normal function of the body.

In the given question, dual stress response gets activated which prepares the body for fight or flight response. The hypothalamus releases molecules which activate the pituitary glands to release the corticotropin-releasing factor which acts on the adrenal glands and form the cortisol and on the other side produce catecholamines which produce fight or flight response.

Thus, Hypothalamus and Pituitary gland are correct.
