A muscle fiber is composed of many fibrils, which give the cell its striated appearance.A smooth muscle cell is a spindle-shaped myocyte with a wide middle and tapering ends, and a single nucleus. Like striated muscle, smooth muscle can tense and relax. In the relaxed state, each cell is 30–200 micrometers in length, some thousands of times shorter than a skeletal muscle cell. [1]Smooth muscle is made of single, spindle-shaped cells. It gets its name because no striations are visible in them.

Match the muscle fiber structure with its function. glycogen - energy storage for muscle contraction.Each skeletal muscle cell, also called a muscle fiber, develops as many embryonic myocytes fused into one long, multi-nucleated skeletal muscle cell. These muscle fibers are bound together into bundles, or fascicles, and are supplied with a rich network of blood vessels and nerves. The fascicles are then bundled together to form the intact muscle.

a) smooth muscle cell does not contain enough calcium to maintain contraction for long periods of time. Once four Ca++ ions bind to the calmodulin, the Ca- calmodulin complex binds to the myosin light chain kinase and activates it. b) a protein that in humans is encoded by the CALD1 gene. Skeletal Muscle. Skeletal muscle has striations across its cells caused by the arrangement of the contractile proteins actin and myosin. These muscle cells are relatively long and have multiple nuclei along the edge of the cell. Skeletal muscle is under voluntary, somatic nervous system control and is found in the muscles that move bones. The cells are interconnected physically and electrochemically to act as a syncytium. Cardiac muscle cells contract autonomously and involuntarily. Smooth muscle is involuntary. Each cell is a spindle-shaped fiber and contains a single nucleus. No striations are evident because the actin and myosin filaments do not align in the cytoplasm.Instagram:https://instagram. harry hines in dallas tx Which type of muscle cell(s) is (are) striated?
