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.


Damage to this fiber type would lead to a loss of sensory function?

ventral root of a spinal nerve


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 does the ventral root of a spinal nerve do?

the ventral root carries motor response


What would happen if the ventral root of a spinal nerve were damaged?

Loss of both motor and sensory function


The motor root of the spinal nerve is also referred to as the?

ventral root


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.


What part of the spinal nerve consists of motor fibers leaving the spinal cord?

The ventral root.


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.


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).


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
