How does mitosis occur in muscle cells?

When cells specialize they basically shut off all other functions that normal body cells do. This is called differentiation and it is bit like school. At first you learn about everthing (math, science, history, etc.) but as you continue to college, you choose your specialty and focus on that for the rest of you career. read more

A nerve cell and muscle cell have a specific function to perform and are well "differentiated" as it they have all the machinery that is required to carry out those functions. And for this to happen, they have to QUIT the cell cycle (the cyclical events that result in mitosis) and just remain metabolically active and perform their function. read more

While most cells undergo both mitosis and cytokinesis at the same time, some do not. For example, your skeletal muscle is a multinucleated tissue which does not contain discrete cell limits, so mitosis occurs without cytokinesis in that tissue. read more
