Block 2 Autonomic Nervous System Flashcards
ANS is solely blank
efferent
two ANS subdivisions
sympathetic, parasympathetic
emybronic origin of sympathetic and parasympathetic
neural crest
preganglionic neuron is in the blank
cns
postganglionic neuron is in the blank
pns
preganglionic sympathetic fibers travel in the blank root of the spinal nerve before entering sympathetic trunk via blank
ventral, white rami communicans
postganglionic sympathetic fibers are contained within ever spinal nerve and goes to where
all hair follics, blood vessels, sweat glands
preganglionic parasympathetic fibers leave the spinal nerve as the blank
pelvic splanchnic nerves
site of information exchange within nervous system
synapse
cell body and fiber originate in the brain and spinal cord
preganglionic
cell body and fiber originates in PNS within a ganglion
postganglionic
collection of cell bodies in cns
nucleus
collection of cell bodies in pns
ganglion
preganglionic neuron is always in the blank of the cns
lateral horn
sympathetic preganglionic neuron originates at one of these levels of the spinal cord
T1-L2 or L3
postganglionic neuron is always in the pns and can be located in the blank or blank
sympathetic trunk, prevertebral ganglia
