Why is cardiac muslce classified separately from smooth muscle or straited muscle?

Question

Question

Answer 1

Answer #1

Cardiac muscles form the myocardium of the heart.

Cardiac muscles are classified seperately from skeletal and smooth muscles because of the following reasons:

1. Cardiac muscles are striated as skeletal muscles but involuntary

2. They are multinucleated and nucleus is located centrally

3. They contain intercalated disks which helps in cell to cell communication and produces contraction of cardiac muscles

4. Cardiac muscles do not require any neural signals to initiate contraction.

Skeletal muscle is striated and under voluntary control. Cardiac muscle is also striated but under involuntary control. Smooth muscle is not striated and is under involuntary control. Explain why we see striations in both skeletal muscle and cardiac muscle but not in smooth muscle. Also explain what it means to be under voluntary or involuntary control.
