Spinal Nerve Innervation Chart

Spinal Nerve Innervation Chart - The chart depicts the intervertebral foramina between each vertebra where the spinal nerves exit. Outside the vertebral column, the nerve divides into branches. The roots connect via interneurons. Grossly, the root fibers join together within the intervertebral foramina to form a spinal nerve. Lumbar spinal nerves carry sensory and motor information to the lower body. Describe the sensory and motor components of spinal nerves and the plexuses that they pass through. A dermatome is an area of skin supplied by a single spinal nerve. Carries sensory (afferent) information to the spinal cord. Web the relevant anatomy of the innervation of the musculature of the back by the spinal nerves is centered around the lumbar spinal nerves, peripheral nerves of the lumbar plexus, spinal cord, and lumbar vertebral column.
