ANATOMY

Detailed explanation-1: -The cardiac muscle cell has one central nucleus, like smooth muscle, but it also is striated, like skeletal muscle. The cardiac muscle cell is rectangular in shape. The contraction of cardiac muscle is involuntary, strong, and rhythmical.

Detailed explanation-2: -Cardiac muscle has branching fibers, one nucleus per cell, striations, and intercalated disks. Its contraction is not under voluntary control.

Detailed explanation-3: -Smooth muscle is made up of cells that contain a single central nucleus. The cells stick together and are connected by specialised cell junctions, called gap junctions. The cells are spindle shaped, and the nucleus is central.

Detailed explanation-4: -Explanation: Skeletal muscle tissue has the most nuclei out of the different types. Cardiac has one or two nuclei per fiber, and smooth muscle cells only have one.

Detailed explanation-5: -Skeletal muscle cells are multinucleated from the fusion of muscle cells. Smooth muscle cells are strictly mononucleated, and cardiac muscle cells are mononucleated in humans.
