The metatarsophalangeal articulations are of the condyloid kind, formed by the reception of the rounded heads of the metatarsal bones in shallow cavities on the ends of the first phalanges.

Elseviers logo Elsevier, the worlds largest publisher of medical and scientific literature, forms part of the Reed Elsevier group. ... In a condyloid joint (condyloid articulation, ellipsoidal joint) an ovoid articular surface, or condyle, is received into an elliptical cavity in such a manner as to permit of flexion, extension, adduction, abduction, and circumduction, but no axial rotation. ... The metatarsus consists of the five long bones of the foot, which are numbered from the medial side (ossa metatarsalia I.-V.); each presents for examination a body and two extremities. ... The phalanges in a human hand The name Phalanges is commonly given to the bones that form fingers and toes. ...

The ligaments are the plantar and two collateral. A ligament is a short band of tough fibrous connective tissue composed mainly of long, stringy collagen molecules. ...

Plantar Ligaments

The Plantar Ligaments (ligamenta accessoria plantaria; glenoid ligaments of Cruveilhier).—The plantar ligaments are thick, dense, fibrous structures.

They are placed on the plantar surfaces of the joints in the intervals between the collateral ligaments, to which they are connected; they are loosely united to the metatarsal bones, but very firmly to the bases of the first phalanges.

Their plantar surfaces are intimately blended with the transverse metatarsal ligament, and grooved for the passage of the Flexor tendons, the sheaths surrounding which are connected to the sides of the grooves.

Their deep surfaces form part of the articular facets for the heads of the metatarsal bones, and are lined by synovial membrane. The synovium or synovial membrane is a thin, weak layer of tissue which lines the non-cartilaginous surfaces within the joint space, sealing it from the surrounding tissue. ...

Collateral Ligaments

The Collateral Ligaments (ligamenta collateralia; lateral ligaments).—The collateral ligaments are strong, rounded cords, placed one on either side of each joint, and attached, by one end, to the posterior tubercle on the side of the head of the metatarsal bone, and, by the other, to the contiguous extremity of the phalanx. The phalanges in a human hand Bones of the human hand. ...

The place of dorsal ligaments is supplied by the Extensor tendons on the dorsal surfaces of the joints.

Movements

The movements permitted in the metatarsophalangeal articulations are flexion, extension, abduction, and adduction. In anatomy, Flexion is movement whereby bones or other objects are brought closer together. ... In metaphysics, extension is the property of taking up space; see Extension (metaphysics). ... // Introduction The movement of body structures is accomplished by the contraction of muscles. ... In anatomy and physiology, adduction is the moving of limbs towards the midline of the body. ...
