Human skeletal and cardiac muscle primarily express the KNCJ2 (K ir 2.1) and KCNJ12 (K ir 2.2) genes in both the sarcolemma and the T tubule membranes. The activation of the KCNJ2 and KCNJ12 channels is initiated during the onset of the activating action potential but there is a slight delay in channel opening such that repolarization is ...There are two major types of cardiac muscle cells: myocardial contractile cells and myocardial conducting cells. The myocardial contractile cells constitute the bulk (99 percent) of the cells in the atria and ventricles. Contractile cells conduct impulses and are responsible for contractions that pump blood through the body.
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 ...Cardiac muscle tissue is a specialized, organized type of tissue that only exists in the heart.

Skeletal muscle attaches to the bone by tendons, and together they produce our bodies movements. But it has important roles in health beyond voluntary movement. Human skeletal muscle is a very responsive tissue. Humans skeletal muscle makes up roughly 40% of total body weight and a huge 50-75% of all the bodies proteins.

Both cardiac and skeletal muscles possess striations. Explanation Muscle tissue in the body is of three types: skeletal, cardiac, and smooth. 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.
