Give three features of cardiac muscles

The three main features of cardiac muscles are: they are involuntary, they are striated, and they do not get tired easily.

Cardiac muscles are special muscles found only in the heart. They make sure the heart beats continuously throughout life. These muscles are not under our control (involuntary), yet they have striations like skeletal muscles. They are strong and rhythmic, allowing them to pump blood without rest.

Features of cardiac muscles

• Involuntary control – They work automatically without conscious effort.
• Striated appearance – They have light and dark bands like skeletal muscles.
• Do not fatigue – They keep working without getting tired.

Other important points

• Branched structure helps in fast conduction of impulses.
• Each cell has a single nucleus.
• Responsible for continuous pumping of blood.
