All of the axons in the dorsal root, which contains afferent nerve fibers, are used in the transduction of somatosensory information. Somatosensory receptors include senses such as pain, touch, temperature, itch, and stretch. For example, a specific muscle fiber called an

Afferent and efferent are connected to affect and effect through their common Latin roots: afferent nerves affect the subject, whereas efferent nerves allow the subject to effect change.
