Question

Which of the following is characteristic feature of the striated muscle?

• A. It has repeating sarcomeres
• B. They are spindle shaped
• C. It has intercalated disc
• D. None of these

Answer 1

The correct option is A It has repeating sarcomeres

Spindle-shaped cells are present in smooth muscles.
Heart muscles or cardiac muscles contain intercalated discs.
Muscle cells are composed of muscle fibers or myocytes. These muscle fibers are in turn composed of many chains of myofibrils. Myofibril consists of long proteins like actin, myosin and titin and other accessory proteins. All these proteins are organized into thin and thick filaments, which repeat along the length of the myofibril. The sarcomere is contractile unit of striated muscle. It is present in between two Z lines.

option A is correct
