  2. Muscular system - Wikipedia

    en.wikipedia.org/wiki/Muscular_system

    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

  3. Somatic nervous system - Wikipedia

    en.wikipedia.org/wiki/Somatic_nervous_system

    The somatic nervous system (SNS), also known as voluntary nervous system, is a part of the peripheral nervous system (PNS) that links brain and spinal cord to skeletal muscles under conscious control, as well as to sensory receptors in the skin. [1] [2] The other part complementary to the somatic nervous system is the autonomic nervous system ...

  4. Skeletal muscle - Wikipedia

    en.wikipedia.org/wiki/Skeletal_muscle

    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 .

    So, you can think of muscle memory as your body’s GPS system: part neurological, part structural, says Rothstein. The first time you try a move, you’re “following directions,” he says.

  6. Muscle - Wikipedia

    en.wikipedia.org/wiki/Muscle

    Muscle is a soft tissue, one of the four basic types of animal tissue. Muscle tissue gives skeletal muscles the ability to contract. Muscle is formed during embryonic development, in a process known as myogenesis. Muscle tissue contains special contractile proteins called actin and myosin which interact to cause movement.

  7. Human musculoskeletal system - Wikipedia

    en.wikipedia.org/wiki/Human_musculoskeletal_system

    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]

  8. Sphincter - Wikipedia

    en.wikipedia.org/wiki/Sphincter

    Functional sphincters do not have this localised muscle thickening and achieve their sphincteric action through muscle contraction around (extrinsic) or within (intrinsic) the structure. Sphincters can also be voluntarily or involuntarily controlled: Voluntary sphincters are supplied by somatic nerves.

  9. Motor cortex - Wikipedia

    en.wikipedia.org/wiki/Motor_cortex

    It is believed that as an animal learns a complex movement repertoire, the motor cortex gradually comes to coordinate among muscles. [65] [66] Map of the body in the human brain. The clearest example of the coordination of muscles into complex movement in the motor cortex comes from the work of Graziano and colleagues on the monkey brain.
