Question

Identify the statements as true/false. (xi) A double chain of ganglia, one on each side of the nerve cord belongs to the spinal cord.

Answer 1

True.

• A spinal ganglion is a cluster of nerve bodies positioned along the spinal cord at the dorsal and ventral roots of a spinal nerve.
• The dorsal root ganglia contain the cell bodies of afferent nerve fibres (those carrying impulses toward the central nervous system).
• Efferent neurons (carrying motor impulses away from the central nervous system) are present in the ventral root ganglia.
