Where Is Rootlets Found?

Posterior rootlets are prolongations of pseudounipolar nerve cells located at dorsal root ganglions (DRGs). Rootlets join to form the anterior roots (from 6 to 8 anterior rootlets) and posterior roots (from 8 to 10 posterior rootlets).

What are spinal rootlets?

These rootlets carry nerve fibers both toward and away from the spinal cord. The dorsal rootlets carry sensory (afferent) fibers to the spinal cord, and ventral rootlets carry motor (efferent) fibers away from the spinal cord.

Where is the epidural space?

The epidural space is the area between the dura mater (a membrane) and the vertebral wall, containing fat and small blood vessels. The space is located just outside the dural sac which surrounds the nerve roots and is filled with cerebrospinal fluid.
