  1. Spinal Nerves
    SA (exteroceptive)
    sensitive to discriminative (fine) touch, nondiscriminative (crude or poorly localized) touch, pain and temperature
  2. Spinal Nerves
    SA (proprioceptive)
    sensitive to stimuli from muscles, tendons, joints
  3. Spinal Nerves

    sensitive to nociceptive stimuli from viscera
  4. Neurotransmitters for SA and VA spinal nerves?
    glutamate, substance P, CGRP
  5. Spinal Nerves
