Autonomic Nervous System

Question 1

What are the 2 motor outputs to the sympathetic nervous system?

Answer 1

1.) descends from the brain
2.) inputs from afferents synapses on neurons in the intermediolateral cell column (gray matter)

Question 2

Where is the SNS located?

Answer 2

T1-L3

Question 3

Where does the SNS neurons send efferent axons through?

Answer 3

the white rami communicants to a paravertebral ganglion

Question 4

What can the axon do within the paravertebral ganglion?

Answer 4

Option 1: Synapse within the paravertebral ganglion at that spinal level

Option 2: Continue to another paravertebral ganglion at a different spinal level and synapse there

Option 3: Pass through the paravertebral ganglion and continue to a prevertebral ganglion (through a splanchnic nerve) and synapse there

Question 5

Where is the intermediolateral horn/column located?

Answer 5

In lamina VII of the thoracic and upper lumbar spinal cord
