Spinal cord disorders are anatomically related disorders to this is easy to point out now at this level of discussion. Currently there is no way to repair a spinal nerve. Once it is cut, that’s it, it’s severed and there’s no way to connect them again.

Spinal cord damage

Paralysis—loss of motor function

Paraesthesia—loss of sensation

Paraplegia—injury to the spinal cord is between T1 and L2 (What is located below L2?)

Paralysis of the lower limbs
