when a dorsal root of a single spinal cord segment is cut, the corresponding dermatome on that side of the body loses all sensation.

Respuesta :

The most common symptoms of spinal root avulsion injuries include neuropathic pain, sensory and autonomic dysfunction loss, paralysis of denervated muscles, and damage to both the ventral and dorsal roots of the spine.

Damage to a spinal nerve can result in discomfort, heightened sensitivity, numbness, and muscle weakness. There are various nerve roots from which pain might come. Pain that originates from a single nerve root is referred to as radicular pain. The output to the skeletal muscles would be cut off if a spinal nerve's dorsal root was severed. At that level, the spinal cord is unable to process information. Visceral organ output would be stopped.

Therefore, neuropathic pain, sensory & autonomic dysfunction loss, paralysis of denervated muscles, and injury to both the ventral and dorsal roots of the spine are among the most typical signs of spinal root avulsion injuries.
