GENERAL HISTOLOGY

Detailed explanation-1: -The spinal ganglia or dorsal root ganglia contain the cell bodies of sensory neurons entering the cord at that region. nerve a group of fibers (axons) outside the CNS. The spinal nerves contains the fibers of the sensory and motor neurons.

Detailed explanation-2: -Dorsal root ganglia contain a complex array of sensory neuron cell bodies that have different functions and innervate different targets.

Detailed explanation-3: -The dorsal root is sensory and the ventral root motor; the first cervical nerve may lack the dorsal root. Oval swellings, the spinal ganglia, characterize the dorsal roots. They are formed of nerve cells that give rise to the sensory nerve fibres.

Detailed explanation-4: -Tissue Engineering of the Nervous System Peripheral spinal nerves (Figure 17.2(a)) originate at the dorsal or ventral roots of the spinal cord, while cranial nerves originate from the brainstem. Dorsal roots contain sensory axons which carry signals into the CNS.

Detailed explanation-5: -A dorsal root ganglion (or spinal ganglion; also known as a posterior root ganglion) is a cluster of neurons (a ganglion) in a dorsal root of a spinal nerve. The cell bodies of sensory neurons known as first-order neurons are located in the dorsal root ganglia.
