What is the Difference Between Synchondrosis and Symphysis?
🆚 Go to Comparative Table 🆚The main difference between synchondrosis and symphysis lies in the type of cartilage that connects the bones in these two types of cartilaginous joints.
- Synchondrosis: In a synchondrosis, the bones are joined by hyaline cartilage. This type of joint is typically found in the epiphyseal plates of growing bones in children. The connection between bones in a synchondrosis is immovable, functionally classified as a synarthrosis. An example of a synchondrosis is the joint between the diaphysis and epiphysis of a growing long bone.
- Symphysis: In a symphysis, the bones are joined by fibrocartilage. This type of joint is slightly movable, functionally classified as an amphiarthrosis. Symphysis joints are found at the joints between vertebrae, the pubic symphysis, and the manubriosternal joint.
In summary:
- Synchondrosis joints have hyaline cartilage between the bones.
- Symphysis joints have fibrocartilage between the bones.
Both synchondrosis and symphysis joints play crucial roles in maintaining the structure of the skeletal system, providing support and rigidity.
Comparative Table: Synchondrosis vs Symphysis
The main difference between synchondrosis and symphysis lies in the type of cartilage that connects the bones in these cartilaginous joints. Here is a comparison table highlighting the differences and similarities between synchondrosis and symphysis:
| Feature | Synchondrosis | Symphysis |
|---|---|---|
| Cartilage Type | Connects bones with hyaline cartilage or bone to cartilage | Connects bones with fibrocartilage |
| Examples | Temporary (epiphyseal plate) and permanent (costal cartilage to thoracic cage) | Pubic portions of hip bones, manubrium to sternum, and vertebral column |
| Location | Ribs, costal cartilage, epiphyseal plate (growth region between diaphysis and epiphysis) | Pelvis, chest, and spine |
| Movement | Limited or no movement | Allows limited movement |
| Structure | Hyaline cartilage provides some flexibility and shock absorption | Fibrocartilage provides strength and structure to withstand compression |
Both synchondrosis and symphysis are types of cartilaginous joints that provide support and rigidity to the skeletal system. They are both situated to facilitate connections between the bones and are an integral part of the skeletal system.
