Explanation:
Spinal nerve divides into several branches after passing through its intervertebral foramen. These branches are called rami. A spinal nerve gives off several branches such as anterior ramus, posterior ramus, rami communicantes, and a meningeal branch. The meningeal branch reenters the vertebral cavity through the intervertebral foramen. It serves to supply the vertebrae, vertebral ligaments as well as the blood vessels of the spinal cord, and meninges.
