Fibers & Nerves

Know what types of fibers travel through nerves (e.g. intercostal, vagus, various splanchic & phrenic nerves).

• • Questions to consider:

    1. Are these fibers sensory or motor?

    2. What functional division of the nervous system are they from?

    3. What structures do they supply - an organ, dermatome, or myotome?

  • Consider how a patient might present if one of these nerves is severed or compressed.

  • Know the location of pre-and post-ganglionic cell bodies and fibers of the autonomic nervous system.
