MUSCLE PHYSIOLOGY

Detailed explanation-1: -Each skeletal muscle fiber is a single cylindrical muscle cell. An individual skeletal muscle may be made up of hundreds, or even thousands, of muscle fibers bundled together and wrapped in a connective tissue covering. Each muscle is surrounded by a connective tissue sheath called the epimysium .

Detailed explanation-2: -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. Skeletal muscle fibers occur in muscles which are attached to the skeleton.

Detailed explanation-3: -Muscle tissue Muscle cells are specialized to contract, i.e. create a pulling force to stabilize or move parts of the body. There are three types of muscle cell: skeletal, visceral and cardiac.
