What is ball and socket joint? How does it work?
Answers
Answer:
Ball-and-socket joint, also called spheroidal joint, in vertebrate anatomy, a joint in which the rounded surface of a bone moves within a depression on another bone, allowing greater freedom of movement than any other kind of joint.
The ball and socket joint provides swinging and rotating movements. The articulating bone is received into the cavity of another bone, allowing the distal bone to move around three main axes with a common center. The joint has stabilizing ligaments that limit the directions and extent to which the bones can be moved.
Explanation:
Ball and Socket joints have an angular movement in all directions and have pivot movement. In this form a joint, a more or less rounded head lies in a cup - like cavity.
Example - Shoulder joint,- In this type of joint, the bones can move in two directions in a 360 degree angle
