12

Adrenal Gland

located above kidneys

13

Adrenal Medulla

releases epinephrine 80% and noepinephrine 20%
most cells
directly controlled by SNS
utilization of energy, mobilization of energy reserves

14

Melatonin
regulate circadian cycle

22

Gonads

Female: estrogen and progesterone
Male: testosterone

23
