1. A joint is a point where two or more bones meet, allowing for movement and providing mechanical support.
2. Fixed joints are immovable, such as the sutures in the skull. Another name for them is fibrous joints.
3. Slightly movable joints allow limited movement, such as the intervertebral discs. Another name for them is cartilaginous joints.
4. The type of joint shown is a synovial joint (specifically, a hinge joint).
5. Freely movable joints allow a wide range of motion; another name is synovial joints.
6. The joint shown is a hinge joint, which allows movement in one plane (flexion and extension).
7. The diagram shows a synovial joint, specifically a hinge joint, with labeled parts including articular cartilage, synovial cavity, ligament, and joint capsule.
Parent Tip: Review the logic above to help your child master the concept of joints and movement worksheet.
