[14] [15] There are between 600 and 840 muscles within the typical human body, depending on how they are counted. [ 16 ] [ 17 ] [ 18 ] In the present table, using statistical counts of the instances of each muscle, and ignoring gender-specific muscles, there are 753 skeletal muscles.

Only skeletal and smooth muscles are part of the musculoskeletal system and only the muscles can move the body. Cardiac muscles are found in the heart and are used only to circulate blood; like the smooth muscles, these muscles are not under conscious control. Skeletal muscles are attached to bones and arranged in opposing groups around joints. [8]
There are more than 600 skeletal muscles in the human body, making up around 40% of body weight in healthy young adults. [18] [19] [20] In Western populations, men have on average around 61% more skeletal muscle than women. [21] Most muscles occur in bilaterally-placed pairs to serve both sides of the body.
There are three distinct types of muscle: skeletal muscle, cardiac or heart muscle, and smooth (non-striated) muscle. Muscles provide strength, balance, posture, movement, and heat for the body to keep warm. [3] There are more than 600 muscles in an adult male human body. [4]
Movement is powered by skeletal muscles, which are attached to the skeleton at various sites on bones. Muscles, bones, and joints provide the principal mechanics for movement, all coordinated by the nervous system. It is believed that the reduction of human bone density in prehistoric times reduced the agility and dexterity of human movement.
The iliacus and nearby muscles. The hip flexors are (in descending order of importance to the action of flexing the hip joint): [2] Collectively known as the iliopsoas or inner hip muscles: Psoas major; Iliacus muscle; Anterior compartment of thigh. Rectus femoris (part of the quadriceps muscle group) Sartorius; One of the gluteal muscles ...
Striated or skeletal muscle only contracts voluntarily, upon the influence of the central nervous system. Reflexes are a form of non-conscious activation of skeletal muscles, but nonetheless arise through activation of the central nervous system, albeit not engaging cortical structures until after the contraction has occurred.
