Which of the following part of the human body is responsible for movement ?

Explanation

Muscles are body parts that contract and relax to create movement. When muscles contract, they pull on bones and make body parts move in different directions.

Bones provide structure and support but cannot move by themselves. Tissues and skin cover the body but do not create movement. Muscles are the only body parts that actively produce motion.

Every body movement from walking to blinking happens because muscles contract. This makes muscles directly responsible for all human movement and physical activity.
