This is a table of
skeletal muscles of the
human anatomy.
There are around 650
skeletal muscles within the typical human body. Almost every muscle constitutes one part of a pair of identical

Bilateral may refer to any concept including two sides, in particular:
*Bilateria, bilateral animals
*Bilateralism, the political and cultural relations between two states

muscles, found on both sides, resulting in approximately 320 pairs of muscles, as presented in this article. Nevertheless, the exact number is difficult to define. Different sources group muscles differently, regarding what is defined as different parts of a single muscle or as several muscles. There are also
vestigial muscles that are present in some people but absent in others, such as
palmaris longus muscle
The palmaris longus is a muscle visible as a small tendon located between the flexor carpi radialis and the flexor carpi ulnaris, although it is not always present. It is absent in about 14 percent of the population; this number can vary in Africa ...
.
The 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 muscles of the lower limbs.
The action refers to the action of each muscle from the
standard anatomical position. In other positions, other actions may be performed.
These muscles are described using
anatomical terminology
Anatomical terminology is a form of scientific terminology used by anatomists, zoologists, and health professionals such as doctors.
Anatomical terminology uses many unique terms, suffixes, and prefixes deriving from Ancient Greek and Latin. ...
. The term "muscle" is omitted from muscle names (except when a muscle is an origin or insertion), and the term "bone" is omitted from bone names. The terms "artery" and "nerve" are both used when these structures are mentioned.

Skeletal muscles (commonly referred to as muscles) are organs of the vertebrate muscular system and typically are attached by tendons to bones of a skeleton. The muscle cells of skeletal muscles are much longer than in the other types of musc ...
