The number of nuclei in each muscle cell is typically multiple, as each cell is formed by the fusion of multiple myoblasts during development.

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).Each FC fuses with a specific number of FCMs (2-25) and establishes a unique muscle with a specific size, shape, tendon attachment, and innervation [12,13]. Each embryonic muscle is composed of a single muscle cell with a relatively small number of nuclei, which is ideal for investigating molecular events underlying myogenesis in great detail. Muscle Tissues. There are three types of muscle in animal bodies: smooth, skeletal, and cardiac. They differ by the presence or absence of striations or bands, the number and location of nuclei, whether they are voluntarily or involuntarily controlled, and their location within the body. Efforts to understand the response of arterial smooth muscle cells (SMCs) to injury have led to confusion, in part because of the as-yet-unconfirmed implication that terms such as dedifferentiation, synthetic phenotype, and phenotypic modulation refer to a specific, common mechanism.
