All muscle cells contain striations..

Fascia is the most superficial connective tissue of skeletal muscles and anchors muscles and other organs of the body. Beneath this, each skeletal muscle has three layers of connective tissues that bind the muscle cells together. The outermost layer wrapping the entire muscle organ is the. epimysium.Find step-by-step Biology solutions and your answer to the following textbook question: All types of muscle tissue have _____. A) striated banding patterns seen under the microscope B) cells that lengthen when appropriately stimulated C) a response that can be consciously controlled D) interactions between actin and myosin.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.Smooth muscle (so-named because the cells do not have striations) is present in the walls of hollow organs like the urinary bladder, uterus, stomach, intestines, and in the walls of passageways, such as the arteries and veins of the circulatory system, and the tracts of the respiratory, urinary, and reproductive systems (Figure \(\PageIndex{1}\).a,b).

Figure 4.18 Muscle Tissue (a) Skeletal muscle cells have prominent striation and nuclei on their periphery. (b) Smooth muscle cells have a single nucleus and no visible striations. …Myofibrils are essentially polymers, or repeating units, of sarcomeres. The shortening of the individual sarcomeres leads to the contraction of the individual muscle fibres, leading to muscle contractions. [1] [2]. The sarcomere structures give skeletal muscle its striated appearance and are readily visible on electron microscopy.

The fine structural characteristics of cardiac muscle cells and its myofibril organization in the orb web spider N. clavata were examined by transmission electron microscopy. Although myofibril striations are not remarkable as those of skeletal muscles, muscle fibers contain multiple myofibrils, abundant mitochondria, extensive …All muscle cells originate from the: actin and myosin. Muscle tissue differentiate by cell lengthening with active synthesis of the proteins: skeletal, cardiac, smooth. The three types of muscle tissue are: Skeletal muscle. This type of muscle contains bundles of very long, multinucleated cells with cross-striations.

113) Which of the following is not characteristic of smooth muscle? A) The striations are due to the orderly arrangement of actin and myosin. B) Neurons that innervate smooth muscles are under involuntary control. C) Smooth muscle cells are uninucleate. D) Smooth muscles do not contain sarcomeres.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.moving the limb toward the midline.

Smooth muscle cells do not have striations, while skeletal muscle cells do. Cardiac muscle cells have striations, but, unlike the multinucleate skeletal cells, they have only one nucleus. Cardiac muscle tissue also has intercalated discs, specialized regions running along the plasma membrane that join adjacent cardiac muscle cells and assist in ...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.

Smooth muscle is found throughout the body where it serves a variety of functions. It is in the stomach and intestines where it helps with digestion and nutrient collection. It is found throughout the urinary system where it functions to help rid the body of toxins and works in electrolyte balance. It is found throughout arteries and veins where it … The body contains three types of muscle tissue: skeletal muscle, smooth muscle, and cardiac muscle, visualized here using light microscopy.
