Question

Cell bodies of neurons bringing afferent information into the spinal cord are located in

• A. Dorsal root ganglia
• B. Ventral root ganglia
• C. Gray matter of the spinal cord
• D. White matter of the spinal cord

Answer 1

The correct option is A Dorsal root ganglia

A. dorsal root ganglia

Reason: The spinal cord is the connection center for the reflexes as well as the afferent (sensory) and efferent (motor) pathways for most of the body below the head and neck. The spinal cord begins at the brainstem and ends at about the second lumbar vertebra. The sensory, motor, and interneurons are found in specific parts of the spinal cord and nearby structures. Sensory neurons brings afferent information to the spinal cord. Those have their cell bodies in the spinal ganglion or dorsal root ganglion. Their axons travel through the dorsal root into the gray matter of the cord and interact with interneurons present in the gray matter. So the correct option is A.
