The correct answer is C. 31 pair.<\/p>\n
There are 31 pairs of spinal nerves that arise from the vertebral column. These nerves are divided into eight cervical pairs, twelve thoracic pairs, five lumbar pairs, five sacral pairs, and one coccygeal pair.<\/p>\n
The cervical nerves supply the muscles and skin of the neck, shoulders, and upper arms. The thoracic nerves supply the muscles and skin of the chest, abdomen, and back. The lumbar nerves supply the muscles and skin of the lower back, abdomen, and legs. The sacral nerves supply the muscles and skin of the buttocks, genitals, and lower legs. The coccygeal nerve supplies the muscles and skin of the coccyx.<\/p>\n
The spinal nerves are mixed nerves, meaning that they contain both sensory and motor fibers. The sensory fibers carry information from the body to the brain, while the motor fibers carry information from the brain to the muscles.<\/p>\n
The spinal nerves are responsible for a variety of functions, including movement, sensation, and reflexes.<\/p>\n","protected":false},"excerpt":{"rendered":"
