Segmental
•	radiculopathy—disease of the nerve root as it exits the IVF
•	nerve root is a mixed nerve of sensory and motor
•	document related loss of conduction from the dermatome (sensory)
•	sclerotome is not related to a pinched nerve
•	Tinel sign—distal presentation of pain—rules out radiculopathy
•	somatic lesions do not produce a Tinel sign

Spinal level
•	autonomic nerves
•	play a key role
•	sympathetics and parasympathetics
•	at spinal level deal w/sympathetics
•	nerves we have little to no control
•	not voluntary
•	T1, T2, T3—supply the ganglion to the neck, the post enter through the base of skull through the brain to the eye
•	dilate eye when stimulated
•	blockage of T1-T3 will block preganglionic fibers
•	miosis
•	Horner's syndrome
•	lateral horn (lateral column)—T1-L2
•	as soon as exits the IVF splits from nerve root
•	synapses close to form the ganglion
•	cervical has 3—Stellate ganglion is biggy
•	preganglionic is short—Ach 
•	postganglionic long to organ—NE 
•	every thing is a deficit
