What is ectatic nerve root in th lumbar and sacral area?
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.
What part of a spinal nerve contains only efferent fibers?
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.
What is the most important cranial nerve that the anterior parasympathetic fibers are associated with?
vagus
What branch of the spinal nerve contain autonomic fibers?
The rami communications
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
The anterior root and the posterior root fuse to form?
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).
Structures form by the fusion on the anterior root and posterior nerve root?
Spinal nerve.....
Where do sensory nerve fibers enter the spinal cord?
The dorsal column or medial lemniscus.
Anterior root of the spinal cord is composed of?
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

What part of a spinal nerve contains only efferent fibers?
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.
What cranial nerve detects tastes?
Facial nerve Glossopharyngeal nerve Vagus nerve
What is the most important cranial nerve that the anterior parasympathetic fibers are associated with?

What area of the spinal cord that is destroyed bye polio virus?
destruction of the anterior horn (Motor Nerve) of the spinal cord. The nerve cells can not regenerate.
Does the spinal cord have a backbone?
The spinal cord is a bundle of nerve fibers which is inside of the vertebrae (backbones).
What part of the spinal nerve consists of motor fibers leaving the spinal cord?
