A ball and socket joint is a type of synovial joint where the rounded surface of one bone fits into a cup-like depression in another bone, allowing for a wide range of motion.
- Examples: The hip joint and the shoulder joint are the most well-known ball and socket joints in the human body. 2
- Movements: These joints can move in multiple directions, including flexion/extension, abduction/adduction, rotation, and circumduction. 2
- Structure: The joint is composed of a ball-like structure (humeral head in the shoulder or femoral head in the hip) and a socket (glenoid fossa in the shoulder or acetabulum in the hip). 2
- Function: The ball and socket joint provides the greatest freedom of motion among all joint types, essential for activities like throwing and walking. 1For more detailed information, you can refer to the sources: Wikipedia, Kenhub, and Britannica.
