False Joints
False joints, also called synarthroses, have no joint gap, no hyaline cartilage and no joint capsule.
They usually connect bones which have to move only little against each other. The connection usually consists of
- fiber cartilage (as in the case of intervertebral discs) or this type of joint is called
- ligaments (e.g. between ulna and radius of forearm),
- bone sutures (on skull bone where skull parts still separated after birth grow together) or *hyaline cartilage (like cartilage in real joints, e.g. rib cartilage),
- bony fusions (e.g. on sacrum) or
- muscles (in mammals, for example, the shoulder blade is synsarcotically connected to the thorax).
Real joints, on the other hand, have a joint gap, hyaline joint cartilage and a joint capsule.
