Each cell is spindle shaped with a single nucleus and no visible striations. It is responsible for voluntary movement, produces heat, and protects organs. It is attached to bones and around entrance points to body.
It contracts to pump blood and is found only in the heart. It is responsible for involuntary movement e. It is found on the walls of major organs and passageways. Striated muscle : Muscle tissue in which the contractile fibrils in the cells are aligned in parallel bundles, so that their different regions form stripes visible in a microscope.
Myocyte : A muscle cell. Striation : Muscle tissue in which the contractile fibrils in the cells are aligned in parallel bundles, so that their different regions form stripes visible in a microscope.
Cardiac muscle myocardium : Involuntary, striated muscle that constitutes the main tissue of the walls of the heart. Smooth muscle : Muscle tissue in which the contractile fibrils are not highly ordered, occurring in the gut and other internal organs and not under voluntary control. Next Trial Session:.

They are striated in appearance and are under voluntary control. What are the 4 main functions of skeletal muscle? Terms in this set 4. Heat and Energy. Is skeletal muscle spindle shaped? Muscle Tissue. Skeletal muscle fibers are cylindrical, multinucleated, striated, and under voluntary control. Smooth muscle cells are spindle shaped , have a single, centrally located nucleus, and lack striations.
They are called involuntary muscles. Is skeletal muscle involuntary? Skeletal muscle is voluntary and striated, cardiac muscle is involuntary and straited and smooth muscle is involuntary and non-striated. What does skeletal muscle look like? Similar to cardiac muscle , however, skeletal muscle is striated; its long, thin, multinucleated fibres are crossed with a regular pattern of fine red and white lines, giving the muscle a distinctive appearance.
Skeletal muscle fibres are bound together by connective tissue and communicate with nerves and blood vessels. What is the advantage of skeletal muscle being Multinucleated?
So to be more efficient, multinucleate condition comes for help as many nuclei can control the long cell better. Which muscles contain fascicles? A muscle fascicle is a bundle of skeletal muscle fibers surrounded by perimysium , a type of connective tissue.
There is also a nerve fascicle of axons. How do you build skeletal muscle? To build muscles , your body needs protein. Therefore it is important to include lots of proteins in your new diet. Think about products like chicken, turkey, yogurt, beans, nuts and different kinds of fish. However, don't forget you also need carbohydrates and healthy fats. How do skeletal muscles work? Together, the skeletal muscles work with your bones to give your body power and strength. In most cases, a skeletal muscle is attached to one end of a bone.
It stretches all the way across a joint the place where two bones meet and then attaches again to another bone. These muscles also hold your head high. How many nuclei does skeletal muscle have? Skeletal muscle cells are elongated or tubular. They have multiple nuclei and these nuclei are located on the periphery of the cell. Skeletal muscle is striated. How do you identify skeletal muscle tissue? Skeletal muscle is found attached to bones.
