What does the term "synchondrosis" refer to in the context of joint classification?

The term "synchondrosis" refers specifically to a type of cartilaginous joint. In a synchondrosis joint, the bones are joined together by hyaline cartilage. This type of joint allows for growth and movement to some extent, although it is generally less mobile than synovial joints. Synchondroses are typically found in locations such as the epiphyseal plates in growing bones or the joint between the first rib and the sternum, where the cartilaginous material provides stability while still accommodating growth.

In contrast, fibrous joints are connected by dense connective tissue and typically do not allow for much movement, synovial joints are characterized by a synovial cavity allowing for a wide range of motion, and compound joints involve more than two articulating surfaces. Understanding these classifications helps clarify the functional capabilities and structural characteristics of the different types of joints in the human body.
