ANATOMY

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: -Smooth Muscle Shape and Orientation However, like skeletal and cardiac muscle, smooth muscle is also surrounded and separated by a connective tissue called endomysium.

Detailed explanation-4: -In the muscular system, muscle tissue is categorized into three distinct types: skeletal, cardiac, and smooth.

Detailed explanation-5: -Gastrointestinal tract. Cardiovascular: Blood vessel and lymphatic vessels. Renal: Urinary bladder. Genital: Male and female reproductive tracts. Respiratory tract. Integument: erector pili of the skin. Sensory: Ciliary muscle and iris of the eye. 18-Jul-2022
