Question

Which of the following muscle types is multinucleated and has long fibres?

• A. Skeletal muscle
• B. Cardiac muscle
• C. Smooth muscle
• D. Circular muscles

Answer 1

The correct option is A

Skeletal muscle

Skeletal muscles are striated, voluntary, shaped like long fibres and are multinucleated. At the same time, smooth muscles are nonstriated, involuntary, shaped like almonds (tapered ends) and have one nucleus per cell. Cardiac muscles are striated, involuntary, branched and they have one nucleus per cell.

Circular muscles are found in the earthworm.
