Answer:

The correct answer will be- myofilamants-actin and myosin.

Explanation:

The skeletal muscle is made up of the muscle fibers which are cylindrical cells enclosed by layers. The muscle cell is divided into smaller units, the smallest of which is myofilaments.

The myofilaments are composed of the thin filaments called actin and thick filaments called myosin which together forms the functional unit of a muscle known as the sarcomere. The muscle contraction takes place due to the sliding of these actin and myosin over each other as a result of the signals arrived from the CNS.

Thus, myofilaments-actin and myosin is the correct answer.
