Which of the following pairs is correctly matched?a)Hinge joint - Betw...
Hinge joint - Between vertebrae
This pair is not correctly matched. Hinge joints are found in the body where movement occurs in only one plane, such as the elbow or knee. They allow for flexion and extension, but do not allow for rotational movements. The vertebrae in the spine do not form hinge joints, as they allow for a combination of flexion, extension, lateral bending, and rotation.
Gliding joint - Between zygapophyses of the successive vertebrae
This pair is correctly matched. Gliding joints, also known as plane joints, are found between the flat or slightly curved surfaces of bones. They allow for limited sliding or gliding movements in multiple directions. The zygapophyses, which are bony projections on the vertebrae, form gliding joints with the corresponding projections on adjacent vertebrae. These joints facilitate small movements and help to stabilize the spine.
Cartilaginous joint - Skull bones
This pair is not correctly matched. Cartilaginous joints, as the name suggests, are joints where the bones are connected by cartilage. They allow for limited movement and provide stability. The skull bones are connected by fibrous joints called sutures, which are immovable joints that provide strength and protect the delicate structures of the brain. Therefore, the correct match for cartilaginous joints would be the joints between the ribs and the sternum.
Fibrous joint - Between phalanges
This pair is also not correctly matched. Fibrous joints are joints where the bones are held together by fibrous connective tissue. They are immovable or have limited movement and provide stability. The joints between the phalanges, which are the bones of the fingers and toes, are actually hinge joints, allowing for flexion and extension. The correct match for fibrous joints would be the joints between the bones of the skull or the teeth and the jawbone.
Therefore, the only correctly matched pair among the given options is "Gliding joint - Between zygapophyses of the successive vertebrae."
