Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Cartilaginous joints are of two kinds. In a primary cartilaginous joint (synchondrosis) the bones are united by hyaline cartilage; in a secondary cartilaginous joint (symphysis) the bones are united by fibrocartilage.
Step 2: The growth plate, or epiphyseal plate, is a layer of hyaline cartilage lying between the epiphysis and the metaphysis of a growing long bone.
Step 3: Because the uniting tissue is hyaline cartilage, the growth plate is classified as a primary cartilaginous joint (synchondrosis).
Step 4: It is a temporary joint that permits longitudinal growth of the bone and is usually immovable; it ossifies completely after growth ceases.
Step 5: Examples of secondary cartilaginous joints (fibrocartilage) include the pubic symphysis and the intervertebral discs, while a gomphosis is the peg-and-socket fibrous joint of a tooth in its socket.
Conclusion: The growth plate is a primary cartilaginous joint (option 2).
