Muscles attach to bones directly or through tendons or aponeuroses. Skeletal muscles maintain posture, stabilize joints, support organs, control internal movement, and generate heat. Skeletal muscle fibers are long, multinucleated cells. The membrane of the cell is the sarcolemma; the cytoplasm of the cell is the sarcoplasm.
Cardiac and skeletal myocytes possess highly evolved and organized cytoskeletal arrays called sarcomeres, composed primarily of actin and myosin along with a vast number of associated proteins that provide directed contraction.

All muscle tissues have four functional properties in common which include excitability, contractility, extensibility, and elasticity.
Similar to skeletal muscle, cardiac muscle is striated and organized into sarcomeres, possessing the same banding organization as skeletal muscle (). 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. Cardiac muscle fibers also possess ...What are the 3ish functions of the muscular system? is responsible for body movements, maintains posture, stabilizes joints, and generates heat.

Which of the following is not a difference between cardiac and skeletal muscle?A. Cardiac muscle cells are arranged in layers surrounding hollow cavities in the heartB.Cardiac muscle fibers are also striated but are mononucleated and connected by intercalated discs, allowing for synchronized contractions across the entire heart. In summary, while both cardiac and skeletal muscles exhibit striations, they have distinct controls for contraction due to differences in their function, innervation, and structural ...Smooth muscle fibers are spindle-shaped (wide in the middle and tapered at both ends, somewhat like a football) and have a single nucleus; they range from about 30 to 200 μm (thousands of times shorter than skeletal muscle fibers), and they produce their own connective tissue, endomysium.Although they do not have striations and sarcomeres, …Jan 20, 2024 ...

Musculoskeletal system. The musculoskeletal system (locomotor system) is a human body system that provides our body with movement, stability, shape, and support. It is subdivided into two broad systems: Muscular system, which includes all types of muscles in the body.

Cardiac muscle fibers are joined by special gap junctions called intercalated discs; these discs allow heart activity to be closely coordinated. true. Smooth muscles stabilize joints of the skeleton. False.The muscles all begin the actual process of contracting (shortening) when a protein called actin is pulled by a protein called myosin. This occurs in striated muscle (skeletal and cardiac) after specific binding sites on the actin have been exposed in response to the interaction between calcium ions (Ca ++) and proteins (troponin and tropomyosin) that "shield" the actin-binding sites.Cardiac and skeletal muscle both possess striations.
