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]
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 system: structural support and protection, production of blood cells: bones, cartilage, ligaments and tendons: Muscular system: movement of body, production of heat: skeletal muscles, smooth muscles and cardiac muscle: Endocrine system: communication within the body using hormones made by endocrine glands
Some combined systems are referred to by joint names. For example, the nervous system and the endocrine system operate together as the neuroendocrine system. The nervous system receives information from the body, and transmits this to the brain via nerve impulses and neurotransmitters.
The heart, liver and red blood cells will also consume lactic acid produced and excreted by skeletal muscles during exercise. Skeletal muscle uses more calories than other organs. [69] At rest it consumes 54.4 kJ/kg (13.0 kcal/kg) per day. This is larger than adipose tissue (fat) at 18.8 kJ/kg (4.5 kcal/kg), and bone at 9.6 kJ/kg (2.3 kcal/kg).
Muscles are often paired as agonistic and antagonistic muscles. [20] This can be a bit misleading as, in general, it is groups of muscles working together to either make or cancel a movement. [21] The present table lists some well-known relationships but is not at all complete.
Diagram of skeletal muscle fiber structure. Skeletal muscle cells are the individual contractile cells within a muscle and are more usually known as muscle fibers because of their longer threadlike appearance. [10] Broadly there are two types of muscle fiber performing in muscle contraction, either as slow twitch or fast twitch .
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.
