Articulations of the phalanges

These are ginglymoid joints, connected by the following ligaments;
- Anterior;
- Two Lateral;
- Synovial Membrane.

The arrangement of these ligaments is similar to those in the preceding articulations; the extensor tendon supplies the place of a posterior ligament.

Actions. The only movements permitted in the phalangeal joints are flexion and extension; these movements are more extensive between the first and second phalanges than between the second and third. The movement of flexion is very extensive, but extension is limited by the anterior and lateral ligaments.
