Abstract. The spatial density of mitochondria was studied by thin-section electron microscopy in smooth muscles of bladder, iris and gut in mice, rats, guinea-pigs and sheep. Morphometric data included areas of muscle cell profiles (~6,000 muscle cells were measured) and areas of their mitochondria (more than three times as many).

The nuclei are embedded in the cell membrane (5) to be just inside the cell. This type of tissue occurs in the muscles that are attached to the skeleton. Skeletal muscles function for the voluntary movements of the body. Muscle type 2) Smooth muscle cells are spindle-shaped (6), and each cell has a single nucleus (7).A smooth muscle cell is smaller in size compared to skeletal muscle cells, generally ranging from 20 to 200 micrometres in length. It possesses a spindle-shaped or elongated shape with tapered ends. Unlike skeletal muscle cells, smooth muscle cells possess a single, centrally located nucleus.

The type of muscle that has cells containing multiple nuclei (option C) is skeletal muscle. Unlike cardiac muscle cells and smooth muscle cells, which typically have a single nucleus, skeletal muscle cells are unique as they contain many nuclei. These muscle cells are long and fibrous and are commonly referred to as muscle fibers.
