Question

Select the correct matching of the type of the joint with the example in human skeletal system:

• A. Pivot joint - between third and fourth cervical vertebrae
• B. Hinge joint - between humerus and pectoral girdle
• C. Gliding joint - between carpals
• D. Cartilaginous joint - between frontal and pariental

Answer 1

The Correct Option is C

The question is about identifying the correct type of joint with its example in the human skeletal system. We will evaluate each option's validity based on known facts about human anatomy.

1. Pivot Joint - A pivot joint allows for rotational movement similar to turning a dial. A classic example is the joint between the first and second cervical vertebrae (atlas and axis), not between the third and fourth cervical vertebrae. Therefore, this option is incorrect.
2. Hinge Joint - This joint allows movement in one plane, similar to the opening and closing of a door. An example of a hinge joint is the elbow joint between the humerus and ulna, not between the humerus and the pectoral girdle. Hence, this option is not suitable.
3. Gliding Joint - Gliding joints allow bones to glide past one another in any direction along the plane of the joint - up and down, left and right, and diagonally. A correct example of this type of joint is between the carpals in the wrist. This option is the correct match.
4. Cartilaginous Joint - These are joints where the bones are connected by cartilage, allowing more movement than a fibrous joint but less than a synovial joint. An example includes intervertebral discs in the spine, not between the frontal and parietal bones of the skull, which are joined by sutures (a type of fibrous joint). Thus, this option is incorrect.

Thus, the correct answer is Gliding joint - between carpals.
