Joint

A joint is the location where two or more bones meet in the body, allowing for movement and flexibility. Joints are supported by ligaments, which are strong tissue bands that hold bones together, and often feature cartilage, a smooth tissue that reduces friction and cushions the bones. Different types of joints enable various movements; for example, a ball-and-socket joint like the shoulder allows wide rotation, while a hinge joint like the knee permits bending and straightening. Joints are essential for everyday activities, providing mobility and stability across the body.
