Other clinical features of accessory nerve damage include muscle wasting, partial paralysis of the sternocleidomastoid, and anasymmetrical neckline. Origin and insertion Splenius capitis originates from the spinous processes of C7-T4 and the nuchal ligament. The most superficial muscle in this group is the semispinalis muscle, spanning the thoracic and cervical regions of the vertebral column, with an attachment on the occipital bone of the skull. Hydrophobic spheres that stick to each other and combine to form a helix, Wraps around actin to stabilize the filament, Pull and releases tropomyosin to cover and uncover myosin-binding sites on actin, Calcium concentrations that determine what Troponin's strength is on tropomyosin, Remove Tropomyosin from the myosin-binding sites on actin, Protein that covers the myosin binding sites on actin to prevent a cross bridge from forming, 1. Each skeletal muscle fiber is a single cylindrical muscle cell. The sarcoplasmic reticulum (SR) is a form of endoplasmic reticulum. Superficial is used to describe structures that are closer to the exterior surface of the body. 16 points. Each skeletal muscle has three layers of connective tissue (called mysia) that enclose it, provide structure to the muscle, and compartmentalize the muscle fibers within the muscle (Figure 10.2.1).
