Answer 2

T1,T2, and will ascend and synapse in the superior cervical ganglion

Question 3

Axons that influence the heart arise from

Answer 3

T1-T4, most will ascend to one of the three cervical ganglia. Some will pass directly to the heart

Question 4

What fibers influence the lungs

Answer 4

T2-T4, these preganglionic fibers synapse in the 2,3,4 thoracic ganglia

Question 5

Preganglionic fibers from the upper extremities are carried in

Answer 5

T3-T7. After entering the sympathetic trunk these ascend to the middle/inferior/stellate cervical ganglia where they synapse

Question 6

Fibers that influence abdominal viscera arise from

Answer 6

T5-T12. Synapse in the lower thoracic ganglia. Also may pass through sympathetic trunk to be carried by greater, lesser, and least splanchnic nerves

Question 7

Fibers that influence pelvic viscera arise from

Answer 7

T10-L2 levels. They descend to ganglia in the lower thoracic, lumbar, and pelvic areas

Question 8

Preganglionic fibers carry info from the lower extremities via

Answer 8

T10-L2, these fibers will descend in the sympathetic trunk and synapse with the 2 lumbar through 4 sacral ganglia
