List of skeletal muscles of the homo anatomy.

Skeletal muscles homo sapiens.JPG

1105 Anterior and Posterior Views of Muscles.jpg

This is a table of skeletal muscles of the human beefcake.

There are around 650 skeletal muscles within the typical human being body.[1] [2] [iii] About every muscle constitutes one role of a pair of identical bilateral 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. Dissimilar sources group muscles differently, regarding what is defined as different parts of a single muscle or equally several muscles. At that place are also vestigial muscles that are present in some people only absent in others, such equally palmaris longus muscle.[four] [v]

The muscles of the human body can exist 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 activeness refers to the action of each musculus from the standard anatomical position. In other positions, other deportment may be performed.

These muscles are described using anatomical terminology. The term "musculus" is omitted from muscle names (except when a musculus 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.
