The human musculoskeletal system (also known as the human locomotor system, and previously the activity system) is an organ system that gives humans the ability to move using their muscular and skeletal systems. The musculoskeletal system provides form, support, stability, and movement to the body.
The muscular system is an organ system consisting of skeletal, smooth, and cardiac muscle. It permits movement of the body, maintains posture, and circulates blood throughout the body. [ 1 ] The muscular systems in vertebrates are controlled through the nervous system although some muscles (such as the cardiac muscle ) can be completely autonomous.
Skeletal muscle (commonly referred to as muscle) is one of the three types of vertebrate muscle tissue, the others being cardiac muscle and smooth muscle. They are part of the voluntary muscular system [1] and typically are attached by tendons to bones of a skeleton.
Muscular hydrostats function independently of a hardened skeletal system. Muscular hydrostats are typically supported by a membrane of connective tissue which holds the volume constant. Retaining a constant volume enables the fibers to stabilize the muscle's structure that would otherwise require skeletal support. [9]
Other tissues in skeletal muscle include tendons and perimysium. [3] Smooth and cardiac muscle contract involuntarily, without conscious intervention. These muscle types may be activated both through the interaction of the central nervous system as well as by innervation from peripheral plexus or endocrine (hormonal) activation. Skeletal muscle ...
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 motor system is a biological system with close ties to the muscular system and the circulatory system. To achieve motor skill , the motor system must accommodate the working state of the muscles, whether hot or cold, stiff or loose, as well as physiological fatigue.
Myology is the study of the muscular system, including the study of the structure, function and diseases of muscle. [1] The muscular system consists of skeletal muscle, which contracts to move or position parts of the body (e.g., the bones that articulate at joints), smooth and cardiac muscle that propels, expels or controls the flow of fluids and contained substance.
