Question

Distinguish between smooth muscle and skeletal muscles.

Accepted Answer

Feature Skeletal Muscles Smooth Muscles

Striations These muscles show striations thus are called striated muscles. These muscles show no striations thus are called non-striated or smooth muscles.

Location These muscles are found attached to the bones hence are also called the skeletal muscles. These muscles are present in the visceral organs.

Feature Skeletal Muscles Smooth Muscles

Action Striated muscles are voluntary in nature which can be controlled by human will. Non-Striated muscles are voluntary and are not under the control of human will.

Feature Skeletal Muscles Smooth Muscles

Muscle Fibres The muscle fibres of smooth muscles are multinucleated and long with pointed ends. The muscle fibres of smooth muscles are uninucleate and spindle-shaped with pointed ends.
