    hypothalamus excites the sympathetic nervous system- special ANS quickens heartbeat... also influences organs like stimulates adrenal glands, especially adrenal medulla- releasing epinephrine and nor-epinephrine, which travel through the system producing arousal and fear. then a second ANS called the PARAsympathetic which returns body processes to normal.
  5. what is the second pathway for fear and arousal?
    hypothalamus signal pituitary gland, which releases ACTH (adrenocorticotropic hormone)- which stimulates the adrenal cortex, which releases a group of hormones- corticosteriods, most notably cortisals- hormones which travel to various organs to produce fear and arousal responses.
