Question

Compared to skeletal muscle, cardiac muscle A. cells are larger and longer than skeletal muscle cells B. lacks striations C. has gap junctions that allow it to act as a functional syncytium D. has more nuclei per cell

Answer 1

Answer:

The correct answer is option C.

Explanation:

Cardiac muscle is present only in the Heart of organisms which is involuntary in its action. The heart helps the blood to pump throughout the body.

Cardiac muscle shows the presence of intercalated discs which contain desmosomes and gap junctions. It is the presence of these gap junctions the muscle cells of the heart functions as a single functional unit due to the transmission of depolarizing current from cell to cell to different chambers of the heart.

Thus, option C is the correct answer.
