Question

Which type of joint is characterised by the presence of a fluid filled cavity and plays a significant role in locomotion
A. Fibrous joints
B. Cartilaginous joints
C. Synovial joints
D. None of the above

Answer 1

The region of the body where two or more bones unite to facilitate movement is called a joint. Except for the hyoid bone in the throat, every bone in the body connects to at least one other bone at a joint. The function of a joint determines its shape. An articulation is another name for a joint.

Complete answer:
Fibrous joints are held together by dense connective tissue, which is mostly collagen. Because they do not move, these joints are often known as fixed or immovable joints. Fibrous joints are joined by fibrous connective tissue and lack a joint cavity. Sutures are fibrous junctions that connect the skull bones.
Cartilaginous joints are totally made up of cartilage (fibrocartilage or hyaline). Cartilaginous joints allow more movement between bones than fibrous joints, although they are less flexible than synovial joints. Cartilaginous joints also form the development zones of immature long bones and the spinal column's intervertebral discs.
A synovial joint, sometimes called diarthrosis, is a fibrous joint capsule that connects bones or cartilage with a fibrous joint capsule that is continuous with the periosteum of the connected bones, forms the outer boundary of a synovial cavity, and covers the articulating surfaces of the bones.
The presence of a fluid-filled synovial space between the articulating surfaces of the two bones distinguishes synovial joints. These joints aid in locomotion as well as a variety of other activities. As a result, synovial joints have a fluid-filled chamber and play an important role in movement.

As a result, the right response is 'synovial joint.'

Note: The muscles and tendons that operate across the joint give additional support at many synovial joints. The dense connective tissue component that connects a muscle to bone is known as a tendon.
