sympathetic anatomy/pathways

Question 1

preganglionic

Answer 1

1st neuron; myelinated
cell bodies in CNS–brainstem or spinal cord
axons extend to autobnomic ganglion

Question 2

post ganglionic

Answer 2

2nd OUTSIDE CNS
not myelinated
cell body in autonomic ganglion
axon to effector organ

Question 3

sympathetic (thoracolumbar) preganglionic cell bodies in

Answer 3

lateral horns of spinal cord T1-L2

Question 4

sympathetic preganglionic axons path

Answer 4

pass through ventral root WHITE RAMI
to chain or collateral ganglia

Question 5

sympathetic chain ganglion

Answer 5

paravertberal
right and left of vertebral column forming a chain
in pairs
extend to cervical and sacral region

Question 6

collateral ganglia

Answer 6

superior or inferior to vertebral column
unpaired
in abdominopelvic cavity

Question 7

sympathetic spinal nerve pathway

Answer 7

1. Pre axons –>white rami–> chain ganglion or collateral –> ascend/ descend to post ganglion–> gray ramus–> spinal nerve

Question 8

sympathetic nerves pathway

Answer 8

pre–> white rami–> chain gang–> sympathetic nerve same or diff level—>post

Question 9

spinal nerves innervate

Answer 9

skin and blood vessels of skeletal muscles

Question 10

sympathetic nerves innervate

Answer 10

thoracic cavity

Question 11

splanchnic nerve target

Answer 11

abdominal cavity

Question 12

splanchnic nerve pathway

Answer 12

pre PASS CHAIN–> synapse directly to POST in COLLATERAL–> target organs

Question 13

Adrenal pathway

Answer 13

Pre —> adrenal medulla via splanchnic nerve (NOT CHAIN OR COLLATERAL)–> NE and Epi

Question 14

cells of adrenal medulla are the same as cells of post ganglionic T/F

Answer 14

TRUE

Question 15

Adrenal medulla

Answer 15

inner portion of the adrenal gland
have no axons or dendrite and are round
80% secrete epi
20% secrete NE

Question 16

sympathetic system known as

Answer 16

flight or fight
