Question

starting at the spinal cord, trace a motor pathway to the adductor muscles of the thigh, Included the spinal cord root, spinal nerve, nerve plexus, and specific peripheral nerve involved in the pathway.

Answer 1

The following are the Spinal cord pathway, both sensory and motor.

peripheral nerve -> sensory pathway --> posterior root -> posterior horn -> anterior horn -> anterior root -> motor pathway

This is also the ascending and descending fiber pathways

* ascending / incoming / afferent / sensory pathways:
- sensory impulses carry different "feeling" (light touch, hot, cold)
Fiber pathways from specific area of body
* outgoing / efferent / descending / motor pathways:
- cause muscles to act
- in white matter of spinal cord
- cross over from one side of body to another in different levels (what
effects in phenomenon of left-sided stroke affecting the right side of
the body)
