ANS control
spinal cord, medulla oblongata + midbrain, ganglia, hypothalamus
two parts of ANS
- sympathetic nervous system
- parasympathetic nervous system
neurotransmitters in ANS
- acetylcholine
- norepinephrine
ANS neurotransmitter for parasympathetic
- acetylcholine
but causes sweatint which is sympathetic a
ANS neurotransmitter for sympathetic
- norepinephrine
what ANS system is the vagus nerve in
parasympathetic
hypothalamus function in ANS
integrator for autonomic functions
Does the ANS have 1 or 2 cells?
2 cells!
1 in spinal cord or brain
the other in automatic ganglion
sympathetic nervous system ganglia location
just outside spinal cord
parasympathetic nervous system ganglia location
near organs they connect with
adrenal medulla function
direct impulse from preganglionic nerve to secrete adrenaline
cortex influence on ANS
- psychic (blushing)
- bladder control unless it’s full
