The dorsal rami of the spinal nerves serve what?
The dorsal rami serve the skin and musculature of the posterior body trunk.
What region of the body is served by the ventral rami of spinal nerves?
The ventral rami serves as a form of intercostal nerves, which supply the muscles between the ribs and the skin and muscles of the anterior and lateral trunk.
Muscle inserts into the mastoid process?
Posterior Belly of Digastric Muscle (innervated by CN VII) Facial nerve Sternocleidomastoid (innervated by CN XI) Spinal accessory nerve Longissimus Capitis (innervated by dorsal rami of C3-C8 spinal nerves) Splenius Capitis (innervated by dorsal rami of middle cervical spinal nerves)
Difference between dorsal ramus and dorsal root?
The roots are two split bases of spinal nerves that connect to the spinal cord. The rami are branches of the spinal nerve that form a complex system throughout the body with the two primary ones being the dorsal (posterior) ramus and the anterior ramus. A diagram would look like an x with the two roots coming together from the spinal cord to go through the intervertebral forming a spinal nerve then splitting again immediately after the intervertebral foramen forming the rami of the spinal nerve
