Smooth Muscle, Cardiac Muscle, & Skeletal Muscle
|
Detailed explanation-1: -Skeletal muscle – the specialised tissue that is attached to bones and allows movement. Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries. Cardiac muscle – the muscle specific to the heart.
Detailed explanation-2: -Cardiac muscle cells (cardiomyocytes) are striated, branched, contain many mitochondria, and are under involuntary control. Each myocyte contains a single, centrally located nucleus and is surrounded by a cell membrane known as the sarcolemma.
Detailed explanation-3: -Smooth muscle is an involuntary non-striated muscle, so-called because it has no sarcomeres and therefore no striations (bands or stripes). It is divided into two subgroups, single-unit and multiunit smooth muscle. Within single-unit muscle, the whole bundle or sheet of smooth muscle cells contracts as a syncytium.
