Smooth and heart muscles differ from skeletal muscles in two main ways:
-
Control Mechanism:
- Skeletal Muscles: Controlled by the brain and can be moved voluntarily.
- Smooth and Cardiac Muscles: Not controlled by the brain and operate automatically.
-
Structure:
- Skeletal Muscles: Have a striped appearance and are long with many nuclei.
- Smooth Muscles: Are not striped, have a single nucleus, and are spindle-shaped.
- Cardiac Muscles: Striped like skeletal muscles but have branches and special connections that help the heart beat in sync.
These differences affect how each type of muscle functions in the body.

The Deep Dive
Smooth muscles are involuntary, meaning they work automatically without conscious control, such as in the walls of organs like the intestines and blood vessels. This allows for the regulation of internal functions without us having to think about it, which is quite the handy feature in keeping our bodies running smoothly!
Heart muscles, or cardiac muscles, have a unique structure that allows them to contract rhythmically and continuously without tiring out. They possess intercalated discs that facilitate communication between cells, ensuring that the heart beats in unison. This is essential for maintaining a steady heartbeat and efficient blood circulation throughout the body, making your heart one fantastic muscle!
