While examining a sample of muscle tissue under a microscope, you notice that the cells are multinucleated. They are long, unbranched, striated, and contain a developed transverse tubule system. Which muscle type does this sample contain?
A)Skeletal muscle
B)Smooth muscle
C)Cardiac muscle
D)Striated muscle

Question

Quizplus · Accepted Answer

Skeletal muscle is characterized by multinucleated, long, unbranched, striated muscle fibers. It also contains a highly developed transverse tubule (T-tubule) system that allows for rapid conduction of electrical signals to the muscle fibers. Smooth muscle lacks striations and typically contains a single nucleus per cell, while cardiac muscle is striated but contains only one or two centrally located nuclei per cell. "Striated muscle" is not a specific type of muscle, but rather a term used to describe both skeletal and cardiac muscle due to their striated appearance.
