Biopsychology

• the hypothalamus activates the pituitary gland which triggers the autonomic nervous system

• Parasympathetic state - resting state
• Sympathetic state - aroused state 

Adrenaline is released from the adrenal medulla (near the kidneys) into the bloodstream

Sympathetic State:

• increased breathing
• increased heart rate
• digestion inhibited
• saliva production inhibited
• pupils dilate
