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

Options

A. Gliding joint - Between carpals
B. Cartilaginous joint - Between frontal and parietal
C. Pivot joint - between third and fourth cervical vertebrae
D. Hinge joint - between Humerus and pectroal girdle

Answer

To solve the question of matching the type of joint with the example in the human skeletal system, we will analyze each option provided:

1. **Gliding Joint between Carpus**:
- Gliding joints allow the articulating bones to slide over one another.
- The carpal bones in the wrist are an example of gliding joints, where the bones can move past each other.
- **Conclusion**: This option is correct.

2. **Cartilaginous Joint between Frontal and Parietal**:
- Cartilaginous joints are slightly movable and typically have a pad of fibrocartilage between the adjoining bones.
- The frontal and parietal bones are actually joined by sutures, which are fibrous joints, not cartilaginous.
- **Conclusion**: This option is incorrect.

3. **Pivot Joint between Third and Fourth Cervical Vertebrae**:
- Pivot joints allow for rotational movement, where one bone rotates around another.
- The pivot joint is found between the atlas and axis (first and second cervical vertebrae), not between the third and fourth cervical vertebrae.
- **Conclusion**: This option is incorrect.

4. **Hinge Joint between Humerus and Pectoral Girdle**:
- Hinge joints allow for movement in one plane, similar to the motion of a door.
- The humerus forms a hinge joint with the ulna at the elbow, not with the pectoral girdle.
- **Conclusion**: This option is incorrect.

Based on the analysis above, the only correct matching of the type of joint with its example in the human skeletal system is:

**Final Answer**: Option A - Gliding joint between carpus.
