Q

What is the autonomic nervous system?

A
  1. innervates blood vessels, viscera, glands, and non striated musculature
  2. ANS changes the activity of somatic structures via afferent and efferent functions

Q

How does the sympathetic nervous system play a role in muscular contraction?

A

SNS is 100% motor and keeps the muscles at 70% contraction during rest and can reach 100% contraction when stimulated even when the nerve is exhausted

Q

Where are the preganglionic cell bodies of the sympathetic nervous system located

Q

What is the pathway for sympathetic white rami synapsing with the gray rami?

A
  1. synapse with the second order neuron in the trunk at the same level it exited. Then the axon of the second order neuron travels the chain to reach the target organ
  2. it can enter the chain and travel to the desired level then synapse with the second order neuron to reach the target organ
  3. they can enter the chain travel up to where they need to go exit the chain and synapse with the second order neuron on the target organ
