Cardiac and skeletal muscle both possess striations..

The correct option is a) a) have striations. Both cardiac muscle cells and skeletal muscle have striations due to the arrangement of sarcomeres. However, cardiac muscles also possess intercalated discs that aid in electrical impulse transmission, a feature not found in skeletal muscles. Explanation: The correct option is a) a) have striations.Cardiac muscle is unique because it is striated, like skeletal muscle, yet involuntary, like smooth muscle. Skeletal muscle controls the body's movement and is generally under conscious, or voluntary, control. The internal organs, on the other hand, with the exception of the heart, are made of smooth muscle, which works without conscious effort.Cardiac and skeletal muscle both possess striations. true. 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. cardiac muscle. Striated involuntary muscle tissue found in the heart is _____. ... The plasma membrane of a skeletal muscle cell is called the _____.

One of the most iconic images in biology is the cross-striated appearance of a skeletal muscle fiber. The repeating band pattern shows that all of the sarcomeres are the same length. All of the A bands are the same length and are located in the middle of the sarcomeres. Furthermore, all of the myofibrils are transversely aligned across the muscle fiber.

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.The body possesses two types of striated muscle, cardiac and skeletal. Human skeletal muscles can be further categorized into slow-oxidative/Type I, fast-oxidative/Type IIa, and fast-glycolytic/Type IIb types based on their contractile and metabolic phenotypes [].Striated muscles are required for whole-body oxygen supply, metabolic …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, smooth muscle fibers do have actin and myosin ...There are 3 types of muscle cells in the human body; cardiac, skeletal, and smooth.

(c) Cardiac muscle cells appear striated and have a single nucleus. From top, LM × 1600, LM × 1600, LM × 1600.

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.To determine the difference between the two types of striated muscle tissue, look for long, multinucleated cells that are arranged parallel to one another in skeletal muscle tissue. By contrast, cardiac muscle cells are shorter and wider, branched, and generally have only one or two nuclei. Intercalated discs are unique to cardiac muscle cells.

Muscle tissue is composed of cells specialized for contraction. Muscle is classified into three types according to their structure and function: Skeletal and cardiac muscle cells are called striated because they show an alternating series of bands. The repeating arrangement of their basic contractile unit, the sarcomere, produces these striations.
