Detailed explanation-1: -Which of the following is NOT a characteristic of skeletal muscle contraction? It contracts rapidly.
Detailed explanation-2: -Skeletal muscle cells are long, cylindrical, and striated. They are multi-nucleated meaning that they have more than one nucleus. This is because they are formed from the fusion of embryonic myoblasts. Each nucleus regulates the metabolic requirements of the sarcoplasm around it.
Detailed explanation-3: -Four characteristics define skeletal muscle tissue cells: they are voluntary, striated, not branched, and multinucleated.
Detailed explanation-4: -Skeletal muscle fibers are red and white. They look striated, or striped, so they’re often called striated muscles. Cardiac muscles are also striated, but smooth muscles aren’t.
