Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -The most important terms of direction for studying spinal cord anatomy are ventral (which means “towards the stomach") and dorsal (which means “towards the back"). Note that in human anatomy, the ventral side of the spinal cord corresponds to the anterior side, and the dorsal side corresponds to the posterior side.
