In cardiac muscle, which feature describes the nuclei location most typical?

• A. Intercalated Disc
• B. Endomysium
• C. Peripheral Nuclei
• D. Centrally Located Muscle Cell Nucleus

Answer: (D)

Cardiac muscle cells are typically uninucleate with the nucleus located in the center of the cell. This central position contrasts with skeletal muscle, where nuclei sit at the periphery because the fibers are long, multinucleated, and densely packed with myofibrils. Intercalated discs are cell junctions between cardiomyocytes, not about where the nucleus sits, and endomysium is the connective tissue surrounding each muscle cell. So the feature that best describes the nuclei location in cardiac muscle is a centrally located nucleus.
