Spinal canal internal spinal nerve simulator

■ The spinal canal internal spinal nerve simulator (anatomical simulator of the brain, spinal cord, and peripheral nerves) displays the morphology, structure, and positional relationship of the brain, spinal cord, spinal nerves, and spinal canal in their natural positions. The spinal canal is connected by the foramen of the free vertebrae and the sacral canal of the sacrum. It is connected to the foramen magnum of the occipital bone and communicates with the cranial cavity, and terminates at the sacral canal hiatus. Its content includes the spinal cord, spinal cord capsule, spinal nerve roots, blood vessels, and a small amount of connective tissue. There are 31 pairs of spinal nerves connected to the spinal cord, distributed in the muscles of the trunk, ventral side, and limbs, responsible for sensation and movement below the neck.
