Skeletal muscle cells are characterized by having multiple nuclei that are located at the periphery of the cell. This multinucleation is a result of the fusion of myoblasts during development, leading to the long, cylindrical, and striated fibers that make up skeletal muscle. The peripheral location of these nuclei is an important feature that allows for efficient management of the large volume of cytoplasm in these long fibers, facilitating the cell's metabolic needs and overall function.

This structural arrangement is important for the muscle's role in voluntary movements, as skeletal muscles need to be able to generate significant force quickly. The multinucleated nature supports greater synthesis of proteins and enzymes needed for energy production and muscle contraction. Additionally, the striations found in skeletal muscle are indicative of its organized contractile proteins, which work together to enable precise and powerful muscle contractions.

In contrast, other muscle types such as smooth and cardiac muscle exhibit different cellular structures and characteristics. For example, smooth muscle cells have a single, centrally located nucleus, and cardiac muscle cells, while also having a single nucleus (sometimes two), are branched and connected by intercalated discs, which facilitate synchronized contractions. Adipose tissue cells, on the other hand, are not muscle cells and
