Median: From 3 Different Sources

A measure of central tendency. The median is found by arranging the values in order and then selecting the one in the middle. If the total number of values is even, then the median is the mean of the two middle numbers. The median is useful where the distribution has extreme values which otherwise skew the data.

Median Nerve

One of the main nerves of the arm. It is a branch of the brachial plexus and runs down the arm from the shoulder into the hand. The median nerve controls the muscles that carry out bending movements of the wrist, fingers, and thumb, and that rotate the forearm palm-inwards. The nerve also conveys sensations from the thumb and first 3 fingers, and from the region of the palm at their base.

Damage to the nerve may result from injury to the shoulder, a Colles’ fracture just above the wrist, or pressure on the nerve where it passes through the wrist (carpal tunnel syndrome).

Symptoms of damage include numbness and weakness in areas controlled by the nerve.... median nerve
