Question:

Select the correct matching of the types of the joint with the example in human skeletal system. Cartilaginous joint - between frontal and pariental; Pivot joint - between third and fourth cervical vertebrae; Hinge joint - between humerus and pectoral girdle; Gliding joint - between carpals

Cartilaginous joint - between frontal and pariental

Gliding joint - between carpals

Hinge joint - between humerus and pectoral girdle

Pivot joint - between third and fourth cervical vertebrae

Solution:

a) Cartilaginous joints are slightly movable joints. In these joints, there is a pad of fibrocartilage between two adjoining bones which allows very slight movements. For example, joints between pubic bones of pelvic girdles and the joints between the vertebrae.
b) 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. For example, a joint between the atlas and axis of mammals.
c) Hinge joints, 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. For example, joints of ankle, knee, elbows etc.
d) In gliding joints, the articulating bones can slide upon one another. For example, the joint between carpals.
So, the correct answer is option D.
