Question

What is a motor point in the central nervous system?

Answer 1

A motor point is a point on the skin at which electrical stimulation causes contraction of a muscle.

Explanation:

(From http://www.ncbi.nlm.nih.gov)

When the electrode is over the motor point (MP), the motor nerve is stimulated.

The electrical impulse mimics the action potential coming from the central nervous system and causes the muscle to contract.

The electrode is usually a pad that is placed over a motor point.

(From en.wikipedia.org)

Electrical muscle stimulation is often used as a rehabilitation tool to prevent the muscle atrophy that often occurs after damage to joints, muscles, ligaments, and tendons.
