chpt 19: ANS Flashcards
ANS overall function
- regulates cardiac, smooth muscles and glandular tissues
which ans system does not effect the liver and adrenal glands
parasympathetic
which organs does the ans innervate
- pupils
- salivary glands
- heart
- bv
- bronchi
- skeletal muscles
- GI tract
- bladder
- liver and adrenal glands (symp sys only)
location of sym system
thoracolumbar (within spc)
which ans sys is located in the carniosacral region
parasympathetic sys
structure of pre-ganglion neuron in sympathetic sys
myelinated and short
where is the post- ganglion neuron long and unmyelinated
sympathetic system
when are pre-gang axons long and myelinated
parasympathetic sys
structure of post g axons in parasympathetic sys
short and unmyelinated
ganglions in autonomic / prevertbral ganglion
- celiac ganglion
- superior mesenteric regions
- inferior mesenteric regions
- aorticorneal regions
what are the autonomic / prevertbral ganglion referring to
pre-g in sympathetic system
superior mesenteric ganglion location
upper abdomen
which ganglion is inferior to the diaphragm
celiac ganglion
which ganglion is in the middle of the abdomen
inferior mesenteric ganglion
location of aorticorenal ganglion
- renal artery
what forms the lesser and greater splanchnic nerves
pre-g axons from sympathetic system
post g in sympathetic system comes from
- superior cervical ganglion
- middle and inferior ganglion
where do pre and post g axons terminate and emerge from in the parasympathetic sys
terminal ganglion
where do pre and post g axons terminate and emerge from in the sympathetic sys
sympathetic truck ganglion
terminal ganglion (4)
- ciliary ganglion
- pterygopalatine ganglion
- submandibular ganglion
- otic ganglion
which CN passes through the ciliary ganglion with pre g axons in para sys
oculomotor nerve (CN3)
which gangion do pre-g and facial nerve (CN7) pass through
pterygopalatine and submandibular ganglion
what CN passes through the otic ganglion in parasympathetic sys
glassopharynheal nerve (CN9)
what does pre g in sympathetic sys release
- ACh
when is ACh releases
- pre g sym
- pre and post g parasympathetic
where is NE and E release
post g sym sys
function of sympathetic sys
fight or flights
which sys is responsible for rest and digest
parasympathetic
what ans sys increases heart rate, bp, breathing blood to sk and blood sugar levels
sympathetic system
when is attention to urinary sys, digestive sys increased
parasympathetic sys
