GNRS 582 EXAM 3 questions with answers
What is the hypothalamic-pituitary- axis? - CORRECT ANSWERS ✔✔It is the
relationship between the; 1. nervous system; 2. endocrine system; and
3. immune system
What systems does the HPA effect in the body? - CORRECT ANSWERS ✔✔1.
nervous system: sympathetic branch of the ANS
2. endocrine system: pituitary and adrenal

with alpha receptors only
9. increases BP by vasoconstriction
10. dilates pupils
