Tutorial 103 - The Cartilaginous Joints (Patreon)

The cartilaginous joints are made of cartilage and therefore a bit more movable than fibrous joints, though not as movable as the synovial joints.

Synchondrosis

Almost no movement at all, these joints are found between the ribs and sternum.

Symphysis

A little more movable, these joints are found in the intervertebral discs of the spine and between the pubic bone.

The fact that some joints are able to assist in certain motions and others are able to restrict is important for the artist to keep in mind.
