Definition
| Dorsal ramus innervate deep muscles of the trunk responsible for movements of the vertebral column. Ventral Ramus what they innervate depends on what part of the spinal cord is considered. Thoracic region: form intercostal nerves that innervate the intercostal muscles. Remaining spinal nerve ventral rami (roots of the plexus): form five plexuses (intermingling of nerves) |
