. Explain Joints and its parts


Best Answer

The point where two bones articulate with each other is known as joint.

There are three main types of joints.

1. Fibrous or immovable joints (Synarthroses):

These joints do not allow any movement because the articulating bones are held firmly together by collagen fibres. Sutures present between the skull bones and the articulation of the roots of teeth with sockets of maxillae and mandible, are two examples of such a joint.

2. Cartilaginous or slightly movable joints (Amphiarthroses): In such joints the opposing surfaces of the articulating bones are connected by fibrocartilage. For e.g. joints between the centra of vertebrae, joint at pubic symphysis and between ribs and sternum. Only a limited movement at the joint is permissible.
