What is loss If the anterior root of a spinal nerve is severed?
Wiki User
∙ 14y ago
The anterior or ventral roots carry motor or efferent information from motoneurons in the anterior horn to muscles. This is as opposed to the dorsal roots that convey sensory or afferent informaiton from the periphery to the dorsal horns of the spinal cord. This is not to be confused with ventral rami that subserve intrinsic muscles of the back and neck.
Therefore if a ventral root is severed or cut there would be a loss on motor function to muscles in the distribution of that root (called a myotome).

Why common peroneal nerve is most affected in sciatic nerve injury?
most commonly injured at the neck of the fibula. injury will cause paralysis of muscles of anterior and lateral compartments of leg along with sensory loss on the skin of the dorsum of the foot. there will be loss of dorsiflexion and that will cause foot drop with patient walking on toes of affected foot. patient will also have difficulty in eversion of the foot with foot remaining in inversion.
Can herniated disk cause loss of gas control?
It depends upon which disk is herniated and what nerves it is impinging and for how long. Usually loss of bladder control would be more common, and again there are many factors including which disk, where it is herniated, is it impinging a nerve root or the spinal cord itself.
What part of the brain will cause dizziness nausea and a loss of balance if damaged?
If the vestibulocochlear nerve is damaged, it can cause dizziness, nausea, and a loss of balance. It is also known as the auditory vestibular nerve.
Which type of hearing loss develops when the auditory nerve or hair cells in the inner ear are damaged?
sensorineural hearing loss
How can an injury to a peripheral nerve cause loss of both sensory and motor function?
An injury to a peripheral nerve causes loss of both sensory and motor functions since that specific part is supplied by the motor pathway such as spinothalalmic and corticospinal.
What would be the result of damage to ventral root of a spinal nerve?
Would lead to loss of both sensory & motor function. Ventral ramus is the anterior division of a spinal nerve.
What tipe of spinal injury is irreversible total loss motor and sensory?
severed spinal cord
Would there be a loss of sensory or motor function when someone damages the dorsal root of a spinal nerve?
Yes this can happen when any nerve is damaged but this is a greater danger if its an actual Spinal Nerve.
What would happen if the anterior ramus of a spinal nerve was damaged or cut?
The ventral rami of the spinal nerves carry sensory and motor fibers for the innervation of the muscles, joints, and skin of the lateral and ventral body walls and the extremities... So there would be some some loss of sensation and muscle function, but not total since the nerve bundles overlap at each level... There are also some autonomic nerves associated.
Damage to this fiber type would lead to a loss of sensory function?

What would happen if the ventral root of a spinal nerve were damaged?
Loss of both motor and sensory function
Is ventral root a loss of motor function?
Yes, the ventral root of a spinal nerve is the efferent motor root, consists of axons of motor neurons. It joins the dorsal root to form a mixed spinal nerve, which consists of afferent sensory neurons (from the dorsal root) and efferent motor neurons (from the ventral root). Therefore severing the ventral root will result in a loss of motor function for the myotome supplied by that spinal nerve.
What would happen if the ventral root of a spinal nerve were damage or transected?
There are a number of things that would happen if the ventral root of a spinal nerve were damage or transected, This would mainly cause the loss of the sensory function and there would be neuropathic pain among other effects.
If the anterior horn of gray matter of spinal cord segment T1 is damaged What are the effects of such a condition if any?
there is sensory loss in the medial aspect of the arm
What would happen if the following structures were damaged or transected 1. dorsal root of spinal nerve 2. ventral root of spinal cord 3. ventral ramus of spinal cord?
loss of both the motor and sensory functions
What determines the severity of paralysis?
The level of the paralysis determines its severity. Loss of bodily function and/or nerve counts from top-bottom spinal cord allow someone to examine the extent of the spinal injury.
