MEDICAL 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: -Smooth muscle is found in the wall of hollow organs, passageways, tracts, eye and skin. Fibers of smooth muscle group in branching bundles, which allows for cells to contract much stronger than those of striated musculature.

Detailed explanation-3: -Muscle tissue can be categorized into skeletal muscle tissue, smooth muscle tissue, and cardiac muscle tissue. Skeletal muscle fibers are cylindrical, multinucleated, striated, and under voluntary control.

Detailed explanation-4: -Cardiac muscle, found in the walls of the heart, is also under control of the autonomic nervous system. The cardiac muscle cell has one central nucleus, like smooth muscle, but it also is striated, like skeletal muscle. The cardiac muscle cell is rectangular in shape.

Detailed explanation-5: -Gastrointestinal tract. Cardiovascular-blood vessel and lymphatic vessels. Renal-urinary bladder. Genital-uterus, both male and female reproductive tracts. Respiratory tract. Integument-erector pili of the skin. More items
