How does the structure of cardiac muscle help it perform its function?
a. Its spindle-shaped cells allow it to do smooth movements.
b. Its striations allow for big movements.
c. Its discs allow it to coordinate movement with other cells.
d. Its multinucleated cells allow it to trigger involuntary actions

The correct answer is (a.) Its spindle-shaped cells allow it to do smooth muscles. The structure of the cardiac muscles which is spindle-shaped is very important for the heart to withstand the stretching of the muscles during the contractions. Also for its smooth surface which is very important to prevent any possible blood clot during circulation.

What is a cardiac muscle?

Cardiac muscle is also referred to as myocardium and it can be defined as a type of muscle found only in the heart of vertebrates, which allow for big movements.

Generally, cardiac muscle is made up of bands referred to as sarcomeres (contractile units), which enables involuntary contractions and it's regulated by the sinoatrial node of the heart.

Additionally, the structure of a skeletal muscle through striations, help it to perform its function in living organisms such as big movements.

In conclusion, the discs in a cardiac muscle enables it to coordinate movement with other cells.
