Cardiac and skeletal muscle both possess striations.

This layout gives both muscle types a striated appearance, alternating dark bands of myosin with lighter bands of actin. Only cardiac muscle has intercalated discs and skeletal muscle is the only type that is multinucleated. No muscle type is attached directly to bone, but skeletal muscle is linked to bone via tendons.

Explanation: There are three primary types of muscle tissue: smooth, skeletal, and cardiac. Skeletal muscle and cardiac muscle are striated, but smooth muscle is not. Striations are formed by the organized units of actin and and myosin (sarcomeres) in a linear pattern.

Both cardiac and skeletal muscle tissues are striated and smooth muscle is not, hence its name. Skeletal muscle cells have more than one nucleus, are large and run parallel to each other. Cardiac muscle cells usually have only one, sometimes two, centrally located nuclei and are branched. They also are connected to each other via gap junctions.The fundamental repeat unit within muscle that is responsible for contraction is the sarcomere. The sarcomere consists of a bundle of myosin-containing thick filaments flanked and interdigitated with bundles of actin-containing thin filaments (Fig. 1). The striated appearance of muscle results from the alternation of thick-filament-containing (A-Band) and thin-filament-containing (I-band ...Types of muscle. skeletal muscle. smooth muscle. cardiac muscle. 1.

Furthermore, all of the myofibrils are transversely aligned across the muscle fiber. It has been known for 300 yr that skeletal muscle is striated, but only in the last 40 yr has a molecular understanding of the striations emerged.

Muscle Tissue Composition: All three types—striated (skeletal), unstriated (smooth), and cardiac muscles—are fundamental types of muscle tissues in the human body. Contractions and Relaxations: Each type of muscle is capable of contracting and relaxing, contributing to various physiological processes and bodily functions.

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 ... Skeletal muscles are located throughout the body at the openings of internal tracts to control the movement of various substances. These muscles allow functions, such as swallowing, urination, and defecation, to be under voluntary control. Skeletal muscles also protect internal organs (particularly abdominal and pelvic organs) by acting as an ...SMOOTH MUSCLE.

Study with Quizlet and memorize flashcards containing terms like SKELETAL MUSCLE, CARDIAC MUSCLE, SMOOTH MUSCLE and more.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.
