Human Skeletal System Overview

Skeletal System Overview

• The skeletal system comprises bones, tendons, and ligaments
• Bones provide movement, protection, blood cell creation, body support, and mineral storage
• Muscles enable movement, protection, stability, and posture
• Joints facilitate motion and connection between bones
• Tendons connect muscles to bones
• Ligaments connect bones together

Explore the complex structure of the human skeletal system, including its components such as bones, joints, tendons, and ligaments. This quiz covers the anatomy of the bones in the body, spine, and upper and lower extremities. Test your knowledge on how these structures work together to support movement and stability.
