MUSCLE PHYSIOLOGY

Detailed explanation-1: -Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control. Smooth muscle fibers are located in walls of hollow visceral organs (such as the liver, pancreas, and intestines), except the heart, appear spindle-shaped, and are also under involuntary control.

Detailed explanation-2: -The body possesses two types of striated muscle, cardiac and skeletal.

Detailed explanation-3: -Cardiac muscle is an involuntary striated muscle tissue found only in the heart and is responsible for the ability of the heart to pump blood.

Detailed explanation-4: -Cardiac muscles are the involuntary muscles that are striated. These muscles are found on the wall of the heart and contract and relax at regular intervals. Individual heart muscle cells are known as cardiomyocytes.

Detailed explanation-5: -Cardiac muscles are said to be involuntary because they are not controlled by our will. These muscles are found in heart and are the only muscles which work throughout the life without getting tired or fatigue.
