What are the 3 types of muscle tissue, and how do they differ in location, cell shape, striations, number of nuclei, and control? The three types of muscle tissue are skeletal, cardiac, and smooth. Skeletal muscle is attached to bones, has cylindrical cells, is striated, multinucleate, and voluntary control.Smooth Muscle Cells. Smooth muscle cells are spindle-shaped and have single elongated nuclei. As in cardiac muscle cells, the configuration of the nuclear membranes in smooth muscle cells changes during contraction and relaxation. Smooth muscle cells contain thin (actin) and thick (myosin) contractile filaments as well as cytoskeletal filaments. 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 may be studied using slide #29 #029-1 smooth muscle ... Find the skeletal muscle nuclei and note their peripheral location. Note the intimate contact between capillaries and muscle cells and be sure you can tell where one muscle cell or fiber stops and another begins (you can see parts of four fibers in this picture). ...Skeletal muscle tissue develops through the fusion of individual myoblasts, or early muscle cells. This fusion results in a characteristic multinucleated structure. Because the cells are fused and multinucleated, they form a structural syncytium. Nuclei of skeletal muscle tissue are oval-shaped and located at the periphery of the cell.Smooth muscle may be studied using slide #29 #029-1 smooth muscle ...

Which type of contraction causes a skeletal muscle to shorten?As in humans, Drosophila muscle fibers form by the fusion of diploid myoblasts, creating one cell with multiple nuclei—the myotube or muscle fiber (Figure 1 A). The number of fusing myoblasts determines the number of nuclei per cell. Those nuclei then increase in ploidy via endoreplication, leading to an increase in gene expression and resulting in an increase in cell size (Figure 1 B).Examples of some of the human cell types mentioned in the main text. Nuclei are drawn in blue against the cytoplasm in pink.a Spherical and ovoid nuclei.b The lobed granulocyte lineage.c The lobed monocyte, and some of its differentiated macrophage stages.d Other shapes, including the polyploid megakaryocyte, fusiform fibrocyte and smooth muscle nuclei, and the condensed nucleus of a sperm

Skeletal Muscle Tissue. The striations are evidence of the myofilaments inside the muscle fibers. The position of the nuclei and vascularity are also signs of muscle tissue. You observe a tissue under a microscope. There appears to be a lumen on one side of the tissue. Lining this lumen, the cells seem to have long, fingerlike projections.
