Question

how is a synchondrosis joint structurally classified?
answers: a - e
a bony joint
b ossified joint
c synovial joint
d cartilaginous joint
e fibrous joint

Explanation:

A synchondrosis joint is structurally classified as a cartilaginous joint. Cartilaginous joints are connected by cartilage. In a synchondrosis, the connecting material is hyaline cartilage. For example, the epiphyseal plate in a growing long bone is a synchondrosis (a type of cartilaginous joint). Bony joints (A) are where bones are fused together. Ossified joints (B) is not a standard structural joint classification term. Synovial joints (C) have a synovial cavity and are more complex and movable (like the knee joint). Fibrous joints (E) are connected by fibrous tissue (like sutures in the skull). So, based on the definition of joint structure (material connecting the bones), synchondrosis is a cartilaginous joint.

Answer:

D. Cartilaginous joint
