Select the correct matching of the type of the joint with the example in human skeletal systemA. Gliding joint - Between carpalsB. Cartilaginous joint - Between frontal and parietalC. Pivot joint - between third and fourth cervical vertebraeD. Hinge joint - between Humerus and pectroal girdle |
|
Answer» Correct Answer - A The correct answer is option A #EXPLANATION: A. In gliding joints, the articulating bones can slide upon one another. B. Cartilaginous joints are slightly movable joints. In these joints, there is a pad of fibrocartilage between two adjoining bones which allows very slight movements. C. Pivot joint is a rotatory joint. Here, one bone is fixed and bears a peg-like projection of pivot. The other bone fits over the pivot by a concavity and freely rotates around. D. Hinge joint, a protuberance known as condyle at the end of one bone fits into the corresponding depression of the other. So, the joint allows movement in one place only.
