loss of both the motor and sensory functions
spinal nerve
the ventral root carries motor response
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.
Would lead to loss of both sensory & motor function. Ventral ramus is the anterior division of a spinal nerve.
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.
The end organ or muscle innervated by that particular spinal nerve component would atrophy.
Yes this can happen when any nerve is damaged but this is a greater danger if its an actual Spinal Nerve.
The ventral root.
ventral root
The ventral ramus of a spinal nerve contains both sensory and motor nerve fibers. These fibers innervate the muscles, joints, and skin on the front part of the body.
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.
