Actin filaments, usually in association with myosin, are responsible for many types of cell movements. Myosin is the prototype of a molecular motor—a protein that converts chemical energy in the form of ATP to mechanical energy, thus generating force and movement. The most striking variety of such movement is muscle contraction, which has provided the model for understanding actin-myosin ...

The structure of skeletal muscle cells also makes them unique among muscle tissues. Skeletal muscle cells develop from the fusion of many smaller cells during fetal development, resulting in long, straight muscle fibers that contain many nuclei. When viewed under the microscope, skeletal muscle cells appear to have a striped, or striated ...Similar to skeletal muscle, cardiac muscle is striated and organized into sarcomeres, possessing the same banding organization as skeletal muscle (Figure 1). However, cardiac muscle fibers are shorter than skeletal muscle fibers and usually contain only one nucleus, which is located in the central region of the cell. Using these criteria, there are three main types of skeletal muscle fibers recognized (Table 10.5.1).

Muscle tissue is one of the four basic types of tissues that make up the human body. It is composed of elongated cells arranged in parallel that are capable of contracting and generating a force. Through this unique ability, muscle tissue allows the body, together with its parts and internal organs, to move and continuously adjust their shapes.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.Figure 7.3.1 7.3. 1: The body contains three types of muscle tissue: skeletal muscle, smooth muscle, and cardiac muscle, visualized here using light microscopy. Smooth muscle cells are short, tapered at each end, and have only one plump nucleus in each. Cardiac muscle cells are branched and striated, but short.

The design of the energy metabolism system in striated muscle remains a major area of investigation. Here, we review our current understanding and emerging hypotheses regarding the metabolic support of muscle contraction. Maintenance of ATP free energy, so called energy homeostasis, via mitochondrial oxidative phosphorylation is critical to sustained contractile activity, and this major design ...It’s easy to exercise the muscles you can see—your biceps, your quads—but there are more muscles in your body than just the big ones. We’ve talked before about the muscles in your ...

6 Muscle Introduction Although all cells are capable of some sort of movement, the dominant function of several cell types is to generate force through contraction.
