NERVES Flashcards
what do autonomic nerves supply
organs, involuntary muscles and glands
What structure do autonomic nerves emerge from
lateral horn
where does the lateral horn run
T1 - L2
S2-S4
what does the white ramus do
carry sympathetic fibres from spinal nerve to sympathetic ganglion
what does the grey ramus do
carry sympathetic fibres from sympathetic ganglion back to ventral ramus
what is the sympathetic trunk
distribution mechanism for sympathetic supply to all parts of the body
Sympathetic fibres can synapse;
1) at level of entry
2) run up down sympathetic trunk before synapse
3) pass through trunk and synapse in preaortic ganglion
which nerves synapse in the preaortic ganglion
splanchnic - abdominal viscera -stomach liver etc.
T5-L2
which type of fibre does the sympathetic system carry
motor and pain impulses
which type of fibre does the parasympathetic system carry
sensory
