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.

Detailed explanation-2: -The nucleolus synthesizes ribosomal RNA, which has a major role in protein synthesis. Nucleus of the neuron is large and round and is usually centrally located.

Detailed explanation-3: -In skeletal muscle fibers, the nuclei are distributed along the cell to maximize their internuclear distances. This myonuclear positioning is crucial for cell function.

Detailed explanation-4: -The cells of cardiac muscle, known as cardiomyocytes, also appear striated under the microscope. Unlike skeletal muscle fibers, cardiomyocytes are single cells with a single centrally located nucleus.
