| Anatomical terminology | |
The base of the first metatarsal is not connected with that of the second by any ligaments; in this respect the great toe resembles the thumb.
The bases of the other four metatarsals are connected by the dorsal, plantar, and interosseous ligaments.
- The dorsal ligaments pass transversely between the dorsal surfaces of the bases of the adjacent metatarsal bones.
- The plantar ligaments have a similar arrangement to the dorsal.
- The interosseous ligaments consist of strong transverse fibers which connect the rough non-articular portions of the adjacent surfaces.
