What is the primary composition of the skeletal system?

1. Cartilage

2. Ligaments

3. Muscles

4. Bones

The correct answer is: Cartilage

Cartilage is not the primary composition of the skeletal system. While cartilage is an important component as it provides cushioning and support in various parts of the body, the primary composition of the skeletal system is bones. Bones form the framework of the body, protect internal organs, store minerals, and produce blood cells. Ligaments are fibrous connective tissues that connect bones to other bones, while muscles are primarily responsible for movement and support of the body.
