Both Afferent and Efferent
both sensory and motor
Contains motor & sensory fibers!
The spinal cord consists of nerve fibers that are afferent and efferent.
I believe this hasn't been answered as it is a typo; they probably meant to write sciatic nerve, or ischiatic nerve is composed of L4-S3 spinal and anterior and posterior divisions of the lumbosacral plexus.
The ventral root of the spinal nerve has the efferent fibers and the dorsal root has the afferent. Prior to joining each other in the spine they each consist of only those fibers.

The rami communications
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
Each spinal nerve attaches to spinal cord by a ventral (anterior) root and a dorsal (posterior) root.All spinal nerves are mixed nerves (both motor and sensory).
Spinal nerve.....
The dorsal column or medial lemniscus.
The anterior root is composed of nerve fibers responsible for motor activity (i.e. efferent nerve fibers that will stimulate muscles, etc.). I think some of the things it is composed of include:Gamma motor neurons, alpha motor neurons, preganglionic autonomic neurons

The six Anterior teeth and the the muco-periosteum covering the anterior third of the hard palate are supplied by the Nasopalatine nerve, while the posterior two thirds along with the remaining posterior teeth are supplied by the Greater palatine nerve,,
The ventral root of the spinal nerve has the efferent fibers and the dorsal root has the afferent. Prior to joining each other in the spine they each consist of only those fibers.

destruction of the anterior horn (Motor Nerve) of the spinal cord. The nerve cells can not regenerate.
The spinal cord is a bundle of nerve fibers which is inside of the vertebrae (backbones).
The ventral root.
