Sensory Receptors and Peripheral Nerves
Peripheral nerves are composed of the axons of somatic and visceral sensory neurons and of somatic and autonomic motor neurons, along with the investing connective-tissue sheaths (epineurium, perineurium, and endoneurium; see Landon, 1976; Ross et al., 1995). The axons may be myelinated or unmyelinated (Fig. 2.1; Peters et al., 1976; Willis and Grossman, 1981). Since the emphasis will be on sensory mechanisms, the characteristics of motor axons will not be considered.
