Question

Multiple anterior rootlets arise from the spinal cord and merge to form a single ____________ root, which contains ____________ axons only. These axons arise from cell bodies in the anterior and ____________ horns of the spinal cord. Posterior rootlets arise from a single ____________ root, which contains ____________ axons only. The cell bodies of these neurons are located in a ____________ , which is within the posterior root. Each anterior root and its corresponding posterior root unite within the ____________ to become a spinal nerve.

Answer 1

Answer:

Explanation:

Multiple anterior rootlets arise from the spinal cord and merge to form a single anterior root. which contains Anterior roots contain motor axons only.

These axons arise from cell bodies in the anterior and lateral horns of the spinal cord.

Posterior rootlets arise from a single posterior root,which contains sensory axons only.

The cell bodies of these neurons are located in a posterior root ganglion , which is within the posterior root. Each anterior root and its corresponding posterior root unite within the intervertebral foramen to become a spinal nerve.
