Smooth Muscles vs. Skeletal Muscles: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on November 24, 2023
Smooth Muscles are involuntary muscles found in organs like the stomach, while Skeletal Muscles are voluntary muscles attached to bones for movement.

Key Differences

Smooth Muscles are the type of muscles that work autonomously without our conscious control. On the contrary, Skeletal Muscles function based on our conscious commands, allowing us to move deliberately.

The structural aspect differentiates Smooth Muscles from Skeletal Muscles. Smooth Muscles have spindle-shaped cells with no striations, whereas Skeletal Muscles have long, multi-nucleated fibers with striations visible under a microscope.

In terms of location, Smooth Muscles predominantly exist within walls of hollow internal organs like blood vessels or the digestive tract. In contrast, Skeletal Muscles are usually attached to bones by tendons, facilitating skeletal movement.

The contraction pace and duration of Smooth Muscles tend to be slower and sustained for more extended periods. Skeletal Muscles, however, can contract rapidly but tire more quickly than Smooth Muscles.

From a functional standpoint, Smooth Muscles play a crucial role in activities like digesting food or constricting blood vessels. Skeletal Muscles, in contrast, are pivotal for actions such as running, jumping, or lifting.
