symphysis
Symphyses (singular: symphysis) are secondary cartilaginous joints composed of fibrocartilage (and hence also known as fibrocartilaginous joints). They are considered amphiarthroses, meaning that they allow only slight movement and are all found at the skeletal midline.
Examples
- symphysis pubis between the pubic bones medially
- manubriosternal joint between the sternal body and the manubrium
- xiphisternal joint: in most, becomes a synostosis by the fifth decade
- symphysis intervertebralis: comprises the anterior and posterior longitudinal ligaments and the intervertebral discs
- sacrococcygeal symphysis
- symphysis mandibulae (a.k.a. symphysis mentalis): midline joint between the half bodies of the hemimandibles
