Skeletal muscles are different from other cells in that they have multiple nuclei
its the same
No, skeletal muscle tissue is composed primarily of skeletal muscle cells, which are a type of muscle tissue. Other types of body tissues like epithelial, connective, and nervous tissue are not typically found within skeletal muscle.

Because muscle cells can only contract, not extend, skeletal muscles most work in pairs. While one muscle contracts, the other muscle in the pair relaxes to its original length.
The stripes in skeletal muscle are formed by two different sorts of protein that slide over each other making the cell contract.
Cardiac muscle cells, known as cardiomyocytes, are not long and cylindrical like skeletal muscle cells. Instead, they are typically shorter and branched, which allows them to connect with each other at intercalated discs. These specialized connections enable synchronized contractions essential for effective heart function. Unlike skeletal muscle, cardiac muscle cells also contain a single nucleus and are involuntary in nature.
Cardiac muscle cells, or cardiomyocytes, lack certain organelles typically found in other cell types. Notably, they have fewer mitochondria compared to skeletal muscle cells, but they do contain many due to their high energy demands. However, they generally do not have a well-developed smooth endoplasmic reticulum or large amounts of glycogen granules, which are more prevalent in other types of muscle cells. Additionally, cardiac muscle cells lack satellite cells, which are involved in muscle repair and regeneration in skeletal muscle.
basiccly there are more than two simiraties and differnces but illl tell yhu just 2 : normal cells: tiny and many but only cover parts of yhur body muscle cells: cover most of yhur body andstrong like the other guy said
Your cardiac muscle never gets tired, and it is the only muscle in it's category. Your skeletal muscle gets tired many times, and it has many other skeletal muscles in it's category. Your cardiac muscle is also a lot stronger than you skeletal muscle.Sorry, also your heart is an involuntary muscle. We have no control over it. Whereas skeletal muscles are voluntary, we decide to move them or not.
Skeletal muscles (the ones in arms, legs and other moving parts of the body) have large numbers of nuclei. They are formed during development by the fusion of many single nucleus myoblastcells . Other muscle cells, like the cardiac muscle cells in the heart or smooth cells in the gut, do not fuse and have only one nucleus. For more information see "Molecular Biology of the Cell" published by Garland Press.
Smooth and skeletal muscles do not have intercalated discs because their structural and functional requirements differ from those of cardiac muscle, which does have intercalated discs. Intercalated discs facilitate rapid communication and synchronized contraction between cardiac muscle cells. Skeletal muscle fibers are long, multinucleated, and contract individually, while smooth muscle cells are spindle-shaped and operate more independently, relying on different mechanisms for contraction and signaling. Consequently, the specialized connections found in cardiac muscle are not necessary for the other types of muscle.
Smooth (organs)Cardiac (heart muscle)Skeletal (movement, support, strength)Muscle cells have a nucleus just like other cells. The basic units of a muscle cell are the actin and myosin filaments that slide past each other to allow flexion and extension of your joints.
