Which of the following is NOT a function of the skeletal system?

1. Support

2. Protection

3. Movement

4. Posture

The correct answer is: Posture

Posture is influenced by the skeletal system but is not a direct function attributed to it. The primary roles of the skeletal system are to provide support to the body, protect vital organs, and facilitate movement through the attachment of muscles. Support involves maintaining the shape and structure of the body, while protection refers to safeguarding critical components like the heart and lungs, which are encased within the ribcage. Movement is achieved through the interplay between the skeleton and muscles, as muscles pull on the bones to generate movement at the joints. While good posture is essential for overall health and can be influenced by the way the skeletal system is structured, it is not considered a core function of the skeletal system itself. Instead, posture is a result of the alignment and tension of muscles and bones working together. Therefore, distinguishing posture from the primary functions of the skeletal system clarifies why it is not classified among them.
