The statement is True. Both cardiac and skeletal muscles possess striations. Explanation Muscle tissue in the body is of three types: skeletal, cardiac, and smooth. Both smooth and skeletal muscle possesses actin and myosin. In fact, the crossbridge cycle is identical in both smooth and skeletal muscle. The differences in the two muscle types are the neuronal regulation, the calcium binding proteins they possess and the mode of calcium entry into the cytoplasm of the cells.

This causes the nerve cell to release acetylcholine (Ach) into the muscle cell.-The muscle cell responds to the acetylcholine (Ach) by having AP.-The muscle cell AP travels over the muscle cell membrane and down the t-tubules and causes Ca2+ to be released from the sarcoplasmic reticulum. This floods the inside of the muscle cell with Ca2+ ions.

Cardiac muscle (or myocardium) makes up the thick middle layer of the heart. It is one of three types of muscle in the body, along with skeletal and smooth muscle. The myocardium is surrounded by a thin outer layer called the epicardium (AKA visceral pericardium) and an inner endocardium. Coronary arteries supply to the cardiac muscle, and cardiac veins drain this blood. Cardiomyocytes are the ...The cardiac muscle cells, or cardiomyocytes, possess an endomysium and perimysium but do not have an epimysium. Compared to skeletal muscles, cardiac muscle cells are small and mostly have a single nucleus. Additionally, they are usually branched and composed of regularly arranged sarcomeres in the myofibrils, giving them a striated appearance.It is striated, branched, and contains intercalated discs.
