Question: 1 / 400

What are the three main components of the musculoskeletal system?

Muscles, ligaments, joints

Muscles, bones, connective tissues

The three main components of the musculoskeletal system are muscles, bones, and connective tissues, which include tendons and ligaments. Muscles work to provide movement, bones form the structural framework of the body, and connective tissues like tendons and ligaments play crucial roles in connecting muscles to bones and bones to each other, enabling stability and movement.

Understanding these components helps in comprehending how the musculoskeletal system supports and enables physical activities, as well as its role in protecting vital organs and maintaining posture. While other options mention important structures, they do not encompass the primary components that make up the musculoskeletal system as a whole. For example, ligaments and joints are forms of connective tissues, and while they are important, they do not represent the full spectrum of essential components in the musculoskeletal system.
