|
skeletal muscle, fast contraction speed, multinucleated, voluntary

Detailed explanation-1: -They are spindle-shaped: This option is incorrect as smooth muscles are spindle-shaped. Striated muscles are cylindrical and not spindle-shaped.
Detailed explanation-2: -The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control.
Detailed explanation-3: -Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations. They are called involuntary muscles.
Detailed explanation-4: -Answer and Explanation: The following statement regarding skeletal muscle is NOT true: b) Skeletal muscle can contract rapidly and can maintain the contraction for long periods of activity. Skeletal muscle is the type of muscle in the body that allows us to move, and is responsible for overall body motility.
Detailed explanation-5: -There are three types of muscles in your body: Skeletal muscle: Skeletal muscles are voluntary muscles, meaning you control how and when they move and work. Nerves in your somatic nervous system send signals to make them function.
