Where you get pain
The median nerve provides sensory and motor function to the hand and forearm. It innervates muscles involved in flexion of the wrist and fingers, as well as sensation to the palm and fingers. Injury to the median nerve can result in weakness, numbness, and tingling in the hand and fingers.
An inability to extend the leg would result from a loss of function of the common peroneal nerve, a branch of the sciatic nerve. This nerve provides motor function to the muscles that extend the leg and dorsiflex the foot. Injury or compression of the common peroneal nerve can lead to weakness or paralysis in these muscles, resulting in difficulty extending the leg.
To send messaged to the brain
The function of a nerve can change due to injury, disease, or degeneration, leading to disruptions in communication between the brain and the rest of the body. Nerve function may be impaired, resulting in symptoms like pain, weakness, or numbness. Furthermore, nerves have the ability to regenerate to some extent, which can help restore function over time.
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.

A peripheral nerve function test is performed to test the nerve function in the peripheral nerve. This test is often performed to when there is pain or weakness in the limbs.
At the end of a nerve, there is a synapse, which transfers the signal on to the next nerve until it reaches it's destination - ie. the brain or a muscle. Nerve endings are what we feel the world around us with. Nerve endings are in every part of your body and they are always sensing what is going on around you. They feel the chair against your bottom, the key board under your finger tips, etc.
