Autonomic Nervous System Flashcards
What should you do during an episode of autonomic dysreflexia
Find and fix the stimulus*
elevate head
Cranial nerves that contain visceral efferents
III, VII, IX, X
Oculomotor, facial, glossopharyngeal, vagus
Number of neurons that make up the peripheral pathway of the ANS
2
Where are the preganglionic cell bodies located for the sympathetic division of the ANS
Brainstem or spinal cord
Main purpose of the parasympathetic division of the ANS?
Rest and Digest
Signs of sympathetic activation
Fight or Flight Responses
- pupil dilation
- dry mouth
- blood moves to muscles
Where are the prevertebral structures located
abdomen
Where are the paravertebral structures located
“beads” that run along the vertebral column
act like an elevator
Pain awareness felt in a different area then the injury
Referred pain
4 possible efferent pathways for the sympathetic system
1) synapse in the paravaterbral ganglion on THAT spinal level.
2) synapse in the paravertebral ganglion on a DIFFERENT spinal level
3) pass through para w/o synapsing and go to the PEREVERTEBRAL ganglia (abdomen)
4) pass through para w/o synapsing and go directly to the ADRENAL GLANDS
location of the sympathetic divison
thoracolumbar
location of the parasympathetic division
craniosacral
