Cardiac and skeletal muscle both possess striations..
Introduction. 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.
Cardiac muscle, found in the walls of the heart, is also under control of the autonomic nervous system. The cardiac muscle cell has one central nucleus, like smooth muscle, but it also is striated, like skeletal muscle. The cardiac muscle cell is rectangular in shape. The contraction of cardiac muscle is involuntary, strong, and rhythmical.See Answer. Question: 24) Which of the following muscle types are striated? a. Cardiac muscle b.

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.
1.7.1 Structure of cardiac muscle. Cardiac muscle fibers, or cardiomyocytes, like skeletal muscle fibers, are striated and have a single, central nucleus.

Not the least of these exceptional properties is its ability to initiate an electrical potential at a fixed rate that spreads rapidly from cell to cell to ...In 1510, Leonardo Da Vinci was the first to describe the heart muscle as arranged in longitudinal and transverse fibers and their contraction resulted in shortening and widening of the ventricular cavities. 1 Since then, there has been a divergence in the study of cardiac and skeletal muscle cells because of the complexity in structure and function of cardiac myocytes.
