Question

Quizplus · Accepted Answer

Striated muscle cells, which include skeletal and cardiac muscle cells, are indeed long and cylindrical with many nuclei. Skeletal muscle cells are multinucleated, while cardiac muscle cells typically have one nucleus but are also striated. Cardiac muscle cells are found only in the heart, not in large blood vessels. Cardiac muscle cells typically have a single nucleus, not many. Smooth muscle cells, found in the walls of hollow organs like intestines and blood vessels, do not have T tubules; T tubules are a feature of skeletal and cardiac muscle cells to facilitate rapid transmission of the action potential into the cell.
