. Anatomy, descriptive and applied. Anatomy. Fui 5th tatarsal. Groovefor Tubeiositij Foi ralcaneni Peroneus longus B Fig. 196.—The left cuboid. .-1. .\ntero-internaI view. B. Postero-external view. The articular surfaces are the posterior, anterior, and internal. The posterior surface is smooth, triangular, and concavo-convex, for articulation with the anterior surface of the calcaneus. The anterior surface, of smaller size, but also irregularly triangular, is divided by a vertical ridge into two facets: the inner one, quadrilateral in form, articulates with the fourth metatarsal bone; the outer one, larger and more triangular, articulates with the fifth metatarsal. The internal surface is broad, rough, irregularly quadrilateral, presenting at its middle and upper part a smooth oval facet, for articulation with the external cuneiform bone; and behind this (occasionally) a smaller facet, for articulation with the scaphoid; it is rough in the rest of its extent, for the attachment of strong interosseous liga- ments. To ascertain to which foot the bone belongs, hold it so that its under surface, marked by the peroneal groove, looks downward, and the large concavo-convex articular surface backward toward the holder: the narrow nonarticular surface, marked by the Commencement of the peroneal groove, will point to the side to which the bone belongs. Articulations.—With foiir bones—the calcaneus, external cuneiform, and the fourth and fifth metatarsal bones; occasionally with the scaphoid. Attachment of Muscles.—Part of the Flexor brevis hallucis and a slip from the tendon of the Tibialis posticus. Scaphoid or Navicular Bone (os naviculare pedis) (Fig. 197).—The scaphoid is situated at the inner side of the tarsus, between the astragalus behind and the three cuneiform bones in front. It may be distinguished by its form, being con- cave behind, convex and subdivided into three facets in front. The anterior surface, of an oblong form, is convex from side to side, a
