Question 1

thalamus

Answer 1

shunting area, info comes from brainstem to thalamus and shunted into important points in cerebral cortex

Question 2

hypothalamus

Answer 2

transfers conscious knowledge/sensory info into endocrine signal

Question 3

feedback loop

Answer 3

stress triggers hypothalamus to release corticotrophic releasing hormone (CRH) which travels to pituitary gland. Adrenocorticotrophic hormone (ATCH) is then secreted via exocytosis and travels to adrenal gland. Cortisol is secreted via exocytosis and fats and proteins are broken down, releasing energy. CRH and ATCH release is then inhibited.

**Diverts energy from immune system
