wunder beta🦵 Joints, Tendons, and Ligaments
Discover how joints let your skeleton move, and how tendons and ligaments hold everything together.
What you’ll learn
- Where Bones MeetExplain what joints are and describe hinge and ball-and-socket joints with examples.Joints are where bones meet and are what allow movement. Inside a synovial joint, cartilage and fluid let bones glide. Hinge joints like the elbow bend one way, while ball-and-socket joints like the shoulder move in all directions.
- Holding It All TogetherDistinguish tendons from ligaments by what they connect and the job each does.Tendons connect muscle to bone and pass on the muscle's pull, while ligaments connect bone to bone and hold joints together. Cartilage cushions the bone ends and synovial fluid keeps the joint moving smoothly.
