The task is to match the types of joints in List I with their corresponding descriptions in List II, based on function and location. Here are the steps to find the correct matching:
- Understand the joint types:
- Fibrous joints: Joints that don't allow any movement, typically found in the skull. Hence, it should match with III "Skull, don’t allow any movement".
- Cartilaginous joints: These allow limited movement and are found between adjacent vertebrae. So, it should match with I "Adjacent vertebrae, limited movement".
- Hinge joints: These permit angular movement along one plane, like the knee, which assists in locomotion. Therefore, it should match with IV "Knee, help in locomotion".
- Ball and socket joints: These allow rotational movement, such as the joint between the humerus and pectoral girdle. Accordingly, it matches with II "Humerus and Pectoral girdle, rotational movement".
- Arrange the matches:
- Fibrous joints: A-III
- Cartilaginous joints: B-I
- Hinge joints: C-IV
- Ball and socket joints: D-II
- Select the correct option: The correct answer is A-III, B-I, C-IV, D-II.
This solution shows how joint types correlate with their structural and functional characteristics, leading to a clear match with their descriptions.
