Which of These is Not Characteristic of a Synchondrosis

Question

Which of these is not characteristic of a synchondrosis?
A) absence of a joint cavity
B) bone ends attached by collagen
C) composed of hyaline cartilage
D) not highly movable

Accepted Answer

A synchondrosis is a joint in which the bone ends are united by hyaline cartilage, with no joint cavity present. They are not highly movable and are found primarily in the developing skeleton. Collagen is not usually the primary connective tissue found in synchondroses; instead, fibrocartilage is more commonly found in joints such as symphyses.
