Q

Generally; in the ANS, cell bodies are located where?

A
  1. Preganglionic is in the CNS for both
    - PNS: craniosacral
    - SNS: thoracolumbar T1-L2 spinal segments
  2. Postganglionic outside of the CNS (para or prevertebral) but not on organs for SNS, for PNS they are on organs (terminal)

A

Referred pain
