Socket joint

There are two main types.

“Madam, they are the moveable and the immoveable joints,” Sarah answered. “Very good, my class is doing very well. Now the immoveable joint can be found in the skull and they are all interlocked, so we cannot move them,” said Mrs. Mumtaz. “One of the moveable joint is the ball and socket joint, right teacher? “asked Sarah.

“Yes Sarah, We have two types of moveable joints, the ball and socket joints and the hinge joints. The ball and one socket joint is like the arm and shoulder, while the hinge joint is like the one at the elbow.”

            “That’s it? Aren’t the joint at the vertebrae moveable too?” Sarah asked.”

“Good point, Sarah. The joint at the vertebrae are slightly moveable joint and they can move only a little.”
