Afferent System

Somatic Component

Receptors

Stimuli activate receptor cells in the skin, muscle, and joint.

Different types of stimuli are sensed by these different types of receptor cells.

01. Pain and Temperature

02. Pressure or Distortion

014. Deep Sensation

From these receptors, the signal is carried by the distal axon of the dorsal root ganglion, passed the dorsal root ganglion and to the proximal axon.

There is no synapse!

 

Next: 03. Dorsal Root Ganglion
