Muscles of the human body: Overview

Head | Neck | Torso | Upper limbs | Lower limbs

is is a table of muscles of the human anatomy .ere are approximately 640 skeletal muscles within the typical human, and almost every muscle constitutes one part of a pair of identical bilateral muscles, found on both sides, resulting in approxi

pairs of muscles, as presented in this article. Nevertheless, the exact number is difficult to define because different sources group muscles differently, e.g. regarding what is defined as different pagle muscle or as several muscles. Examples range from 640 to 850. [1] e muscles of the human body can be categorized into a number of groups which include muscles relating to the head and neck, muscles of the torso or trunk, muscles of the upper limbs, and muscler limbs.

e action refers to the action of each muscle from the standard anatomical position . In other positions, other actions may be performed.
