The nerve responsible for carrying motor information causing left leg extension is the sciatic nerve, specifically the fibular (peroneal) division which innervates the muscles that extend the leg.
Optic Nerve
The cranial nerves that have some function in vision include the optic nerve (II), which is responsible for carrying visual information from the eye to the brain, and the oculomotor nerve (III), which controls the movement of the eye muscles.
An axon is the long extension of a nerve cell body. The dendrites are the short branches.
A mixed nerve, such as the trigeminal nerve, contains both sensory and motor fibers that can send and receive messages. These nerves are responsible for carrying both sensory information from the body to the brain and motor commands from the brain to the muscles.
This means that a nerve in the lower back is being compressed or pinched when the back is extended, the hips are extended, or the spine is bent to the side. These movements put additional pressure on the nerve, causing it to become irritated and potentially leading to pain, numbness, or weakness in the affected area.
