Question

Dorsal Root Ganglion contain: a. Cell bodies of autonomic motor neurons b. Axon terminals of somatic motor neurons c. Cell bodies of somatic motor neurons d. Cell bodies of sensory neurons e. Axon terminals of sensory neurons

Answer 1

The dorsal root ganglion contains the cell bodies of sensory neurons, not autonomic motor neurons, somatic motor neurons, or axon terminals.

Step-by-step explanation:

The dorsal root ganglion contains the cell bodies of sensory neurons. These sensory neurons have axons that extend from the periphery, such as the skin, and connect to the central nervous system (CNS) through the dorsal nerve root. The ganglion appears as an enlargement on the nerve root. Under the microscope, it is clear that the dorsal root ganglion consists of unipolar neuron cell bodies and the fibrous region is composed of the axons passing through the ganglion to form part of the dorsal nerve root. The autonomic motor neuron cell bodies are not found here, but in the autonomic ganglia, while the somatic motor neuron cell bodies are located in the ventral portion of the spinal cord's gray matter.
