GENERAL HISTOLOGY

Detailed explanation-1: -Dorsal root ganglia contain a complex array of sensory neuron cell bodies that have different functions and innervate different targets. Many proteins such as channel proteins are highly related to neuron function.

Detailed explanation-2: -The dorsal root ganglion contains the cell bodies of sensory neurons (afferent fibres), that bring information from the periphery to the spinal cord.

Detailed explanation-3: -Each dorsal root fiber is the central process of a dorsal root ganglion cell. The dorsal roots contain sensory fibers from the skin, subcutaneous and deep tissues, and viscera. Primary afferent fibers of the dorsal roots are either myelinated or unmyelinated.
