Question

Which of the following muscle tissue is found in the upper part of pharynx and external anal sphincter?

• A. Skeletal muscle
• B. Smooth muscle
• C. Cardiac muscle
• D. None of these

Answer 1

The correct option is A Skeletal muscle

Skeletal muscles are attached to the bones of the skeleton. They help in the movement of the body parts.
Upper part of pharynx, tongue, diaphragm and external anal sphincter contain skeletal muscles which are not attached to bones. They are striated and multinucleated.

Smooth muscles are involuntary muscles controlled by the sympathetic and parasympathetic nerves.

Cardiac muscles are contractile tissues found only in the heart. Endocardium of heart is composed of epithelial cells. Cardiac tissues are present in the myocardium (middle muscular layer of heart wall).
