Synchondrosis
Synchondrosis
Synchondrosis (pronunciation: sin-kon-DRO-sis) is a type of joint that is characterized by the presence of a plate of hyaline cartilage that connects two bony structures. The term is derived from the Greek words "syn", meaning "together", and "chondros", meaning "cartilage".
Definition
A synchondrosis is a type of cartilaginous joint where the bones are united by hyaline cartilage. This type of joint allows for little to no movement, making it a synarthrosis joint.
Examples
Examples of synchondrosis joints include the sternocostal joint (the joint between the sternum and the first rib), and the epiphyseal plate (the growth plate within long bones).
Clinical Significance
In the field of orthopedics, understanding the nature and function of synchondrosis joints is crucial. These joints play a significant role in the growth and development of the skeletal system, and any abnormalities can lead to conditions such as skeletal dysplasia or achondroplasia.
