Cerebrum contains
thalamus, basal ganglia, hypothalmus, limbic system
Cerebellum is
in the back (looks like a squiggle) and controls motor and balance
Brain stem contains what
mid brain, pons, medulla
What does the medulla control
controls heart rate, breathing, and everything sympathetic
inhibitory neurotransmitters
open chloride channels allowing negatively charged chloride ions into the cell
excitatory neurotransmitters
open sodium channels causing depolarization in the postsynaptic membrane initiating an action potential
Where do motor neurons come from
Pons
subdural hematoma
occurs when a blood vessel in the space between the skull and the brain (the subdural space) is damaged
Rest and digest
Parasympathetic
Fight or flight
sympathetic
Efferent pathway
motor
