GROSS ANATOMY

Detailed explanation-1: -The ventral roots consist predominantly of efferent somatic motor fibers (thick axons of alpha motor neurons and medium-sized axons of gamma motor neurons).

Detailed explanation-2: -Each spinal nerve contains a mixture of motor and sensory fibres.

Detailed explanation-3: -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-4: -ventral roots (anterior roots) allow motor neurons to exit the spinal cord. dorsal roots (posterior roots) allow sensory neurons to enter the spinal cord.
