are connected together by dorsal, plantar, and interosseous ligaments.


Dorsal ligaments

The dorsal ligaments consist of three transverse bands: one connects the first with the second cuneiform, another the second with the third cuneiform, and another the third cuneiform with the cuboid.


Plantar ligaments

The plantar ligaments have a similar arrangement to the dorsal, and are strengthened by slips from the tendon of the
tibialis posterior The tibialis posterior muscle is the most central of all the leg muscles, and is located in the deep posterior compartment of the leg. It is the key stabilizing muscle of the lower leg. Structure The tibialis posterior muscle originates on the ...

Interosseous ligaments

The interosseous ligaments consist of strong transverse fibers which pass between the rough non-articular portions of the adjacent surfaces of the bones.


Synovial membrane

The synovial membrane of these joints is part of the
great tarsal synovial membrane The great tarsal synovial membrane is a synovial membrane in the foot. The synovial membranes between the second and third, and the third and fourth metatarsal bones are part of the great tarsal synovial membrane; that between the fourth and fifth m ...
.


Movements

The movements permitted between these bones are limited to a slight gliding upon each other.
