[Answer] What types of muscle are striated?

Answer: skeletal and cardiac
What types of muscle are striated?

Striated muscle tissue is a muscle tissue that features repeating functional units called sarcomeres. The presence of sarcomeres manifests as a series of bands visible along the muscle fibers which is responsible for the striated appearance observed in microscopic images of this tissue. There are two types of striated muscles: Cardiac muscle (heart muscle) Skeletal muscle (mu…

Striated muscle tissue contains T-tubules which enables the release of calcium ions from the sarcoplasmic reticulum . Skeletal muscle Skeletal muscle includes skeletal muscle fibers blood vessels nerve fibers and connective tissue. Skeletal muscle is wrapped in epimysium allowing structural integrity of the muscle despite contractions. The perimysium organizes the muscle fibers which are encased in collagen and endomysium into fascicles . Each muscle fiber contains sarcolemma sarcoplasm and sarcoplasmic reticulum . The functional unit of a muscle fiber is called a sarcomere . Each myofiber is composed of actin and myosin myofibrils repeated as a sarcomere. Based on their contractile and metabolic phenotypes skeletal muscle can be classified as slow-oxidative (Type I) or fast-oxidative (Type II). Cardiac muscle Cardiac muscle lies in between the epicardium and the endocardium in the heart. Cardiac muscle fibers generally only contain one nucleus located in the central region. They contain many mitochondria and myoglobin. Unlike skeletal muscle cardiac muscle cells are unicellular. These cells are connected to each other by intercalated disks which contain gap junctions and desmosomes .

Skeletal muscle is one of three major muscle types the others being cardiac muscle and smooth muscle. It is a form of striated muscle tissue which is under the voluntary control of the somatic nervous system. Most skele…
