    Describe all the parts of a sorcerer and their respective functions. The parts of a sorcerer can be detailed once the sorcerer is explained. Myofibril are cylindrical structures that carry out contraction of the muscle. These muscle structures are composed of individual cylindrical subunits called sorcerers. Sorcerers are investments that are contractile, repetitious functional units in muscle (Martini & Nathan, 2009, p. 298). These investments are the smallest operational/functional unit in the muscle.

    Even With these being small, they still have thick and thin filaments, stabilizing proteins for the thick and thin filaments, ND proteins Which regulate interactions Of the thin and thick filaments. Starting with the outside of the sorcerer, there is the sarcoma. Sarcoma is the plasma membrane of skeletal muscle cells. Sarcoma extends to separate the sorcerers. T tubules (transverse tubules) which are responsible for allowing the flow of calcium into the ceroplastic reticulum (SIR) invigilate the sarcoma.

    The sarcoma is not only for protection, but is also a means of communication for nerve impulses that cause the muscle to contract. Longitudinal tubules or investments connect the T tubules to the sarcoma. Bundled longitudinal habiliments that are in an ordered arrangement are called myofibril. The points at which the longitudinal tubules connect the T tubules onto the sarcoma are triad junctions. The triad has a T tubule which is called terminal cistern.

    Mitochondria are in between myofibril and sarcoma. The ceroplastic reticulum (SIR) is specialized endoplasmic reticulum (RE) membrane of each skeletal muscle cell that surrounds the sorcerer. SIR is responsible for the storing and providing the calcium that is required for muscle contraction (Martini & Nathan, 2009, 2981 Looking at the sorcerer section of a myofibril, here are noticeable coloration (striations), lines, and bands. See page 239 for the visualization.

    The bands, A?dark bands (anisotropic) and the light I (isotropic) bands are labeled by letter that corresponds to their appearance under polarize light (Martini & Nathan, 2009, p. 298). The A band is the single dark band in the center of the sorcerer with the H band in the center of the A band along With the M line running through the center. The light I bands are lateral to the A band and have Z line in the center. Here is a little secret that I remember room classes of the past: I bands contain only actinic; A band contains overlapping filaments of actinic and myosin; H band contains only myosin.
