Answer:
False
Step-by-step explanation:
There are three types of vertebrate muscles:
- Skeletal muscles - striated muscles that can be controlled voluntarily. Most of them are attached to bones by tendons.
- Smooth muscles - involuntary non-striated muscles used to apply pressure to vessels and organs.
- Cardiac muscles (also called heart muscles or myocardium) - involuntary striated muscles found only in the heart. The myocardium constitutes the main tissue of the walls of the heart and is responsible for the ability of the heart to pump blood.
Based on this information, we can see that cardiac muscles are not considered smooth muscles, but represent a group of their own.
