Question

Quizplus · Accepted Answer

Spinal nerves are present in 31 pairs - 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal. They emerge from the vertebral column through intervertebral foramina, but are not located exclusively in the vertebral canal. Spinal nerves contain both sensory and motor fibers and are not purely sensory nerves. Plexuses are present in all regions of the spinal cord except for the thoracic region.
