Nervous (coordination and regulation) Flashcards
acetylcholine functions
CNS: stimulates brain, memory,motor control, ect
PNS: stimulates skeletal muscles, inhibits cardiac muscle, promotes digestion
Biogenic amines (3 types) and function
catecholamines, serotonin, histamine
CNS: mood, attention, learning
PNS: cardiac, lung, stress
Amino acids function
mediators of CNS activity, on and off signals
excitatory AA (2)
glutamate, aspartate
inhibitory AA (2)
GABA
glycine
neuropeptides (types) and function
opiate peptides, oxytocin
modulate post synaptic cell, mood, behaviour, appetite
gases types and role
nitric oxide, carbon monoxide
CNS: memory and odor
PNS: relaxed smooth muscle
