Detailed explanation-1: -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-2: -Cardiac muscle, like skeletal muscle, is made up of sarcomeres that allow for contractility. However, unlike skeletal muscle, cardiac muscle is under involuntary control.
Detailed explanation-3: -Skeletal muscle, attached to bones, is responsible for skeletal movements. The peripheral portion of the central nervous system (CNS) controls the skeletal muscles. Thus, these muscles are under conscious, or voluntary, control. The basic unit is the muscle fiber with many nuclei.
Detailed explanation-4: -What Is the Difference Between Voluntary and Involuntary Muscles? Voluntary muscles are skeletal muscles that contract and relax under conscious control. These muscles attach to bones and regulate movement of the body. Involuntary muscles, on the other hand, are not under conscious control.
Detailed explanation-5: -Skeletal muscles are under our conscious control, which is why they are also known as voluntary muscles.
