Question

Quizplus · Accepted Answer

A spinal nerve passing through the intervertebral foramen is associated with the vertebra above it. Each spinal nerve is formed by the combination of dorsal and ventral roots that emerge from the spinal cord at each level. The dorsal root carries afferent fibers while the ventral root carries efferent fibers. However, once the two roots combine to form the spinal nerve, it contains both afferent and efferent fibers. The spinal nerve passes through the intervertebral foramen, which is a space between adjacent vertebrae, and then divides into smaller branches that innervate specific regions of the body.
