There are over 600 skeletal muscles within the typical human body. Almostevery muscle constitutes one part of a pair of identical bilateral muscles,
found on both sides, resulting in approximately 320 pairs of muscles.
Nevertheless, the exact number is difficult to define because different sources
group muscles differently, e.g. regarding what is defined as different parts of a
single muscle or as several muscles.
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.
