brainstem and cranial nerves Flashcards
3 levels of brain stem
midbrain, pons, medulla
functions of brainstem
conduit function
cranial nerve attachment
integrative: respiratory, cardiac and conscious control
functions of reticular formation
motor: reticulospinal tract
modulating pain
influence autonomic activity
modulation of arousal and consciousness
diffuse modulatory network function
maintains and regulates consciousness, attention and mood with the cerebral cortex
examples of chemicals that use the diffuse modulatory network
acetylcholine, histamine, norepinephrine, orexin, serotonin
