extra 4 Flashcards
what kind of nerves have varicosities
autonomic nerves
PNS OR SNS causes contraction of pupils
parasympathetic nervous system
what do presynaptic symapthetic fibres pass thru or synapse at
the paravertebral sympathetic trunk
what do the cranial nervse 3, 7, 9 innervate
the salivary glands and the smooth eye muscles
what is innervated by sympathetic nerves only
peripheral arterioles and sweat glands
where is b2 present
skeletal muscles and bronchioles
where is m2 present
in heart and bladder
what pns or sns innervates most internal organs
both in anagonistic tonic control
what happens to bronchioles in stress
they dialate
where are preganglionic neurons
in spinal chord segments t1-l2
what does the grey ramus join
correspondning spinal nerves to target
what does the grey ramus join
correspondning spinal nerves to target
for the preganglionic sympathetic nerves that pass thorugh the paravertebral sympathetic trunk, where do they synapse
in the collateral ganglia
cervical ganglia
reach the adrenal glands
what do visual based neural signals pass thorugh
the optic nerve, intermediate retinal neurons, retinal ganglion cells/ optic nerve, LGN, visual cortex
far focus sympathetical or parasympathetic
sympathetic
