  2. Muscular system - Wikipedia

    en.wikipedia.org/wiki/Muscular_system

    The muscular systems in vertebrates are controlled through the nervous system although some muscles (such as the cardiac muscle) can be completely autonomous. Together with the skeletal system in the human, it forms the musculoskeletal system, which is responsible for the movement of the body. [2]

  3. Hill's muscle model - Wikipedia

    en.wikipedia.org/wiki/Hill's_muscle_model

    Hill's elastic muscle model. F: Force; CE: Contractile Element; SE: Series Element; PE: Parallel Element. The three-element Hill muscle model is a representation of the muscle mechanical response. The model is constituted by a contractile element (CE) and two non-linear spring elements, one in series (SE) and another in parallel (PE).

  4. Comparative anatomy - Wikipedia

    en.wikipedia.org/wiki/Comparative_anatomy

    Comparative anatomy is the study of similarities and differences in the anatomy of different species. It is closely related to evolutionary biology and phylogeny [ 1 ] (the evolution of species). The science began in the classical era , continuing in the early modern period with work by Pierre Belon who noted the similarities of the skeletons ...

  5. Anatomical terms of muscle - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terms_of_muscle

    For example, the pronator teres muscle of the forearm. Unipennate muscles have fibres that run the entire length of only one side of a muscle, like a quill pen. For example, the fibularis muscles. Bipennate muscles consist of two rows of oblique muscle fibres, facing in opposite diagonal directions, converging on a central tendon.

  6. Myofibril - Wikipedia

    en.wikipedia.org/wiki/Myofibril

    A diagram of the structure of a myofibril (consisting of many myofilaments in parallel, and sarcomeres in series) Sliding filament model of muscle contraction. The myosin heads form cross bridges with the actin myofilaments; this is where they carry out a 'rowing' action along the actin. When the muscle fibre is relaxed (before contraction ...

  7. Skeletal muscle - Wikipedia

    en.wikipedia.org/wiki/Skeletal_muscle

    Muscles are often classed as groups of muscles that work together to carry out an action. In the torso there are several major muscle groups including the pectoral , and abdominal muscles ; intrinsic and extrinsic muscles are subdivisions of muscle groups in the hand , foot , tongue , and extraocular muscles of the eye .

  8. The Clitoris And The Body - The Huffington Post

    From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.

  9. Muscle - Wikipedia

    en.wikipedia.org/wiki/Muscle

    All other muscles, including those of the limbs are hypaxial, and innervated by the ventral rami of the spinal nerves. [ 18 ] During development, myoblasts (muscle progenitor cells) either remain in the somite to form muscles associated with the vertebral column or migrate out into the body to form all other muscles.
