The inner malleolus

This process has a depression 30 [sulcus malleolaris] (k in figs. 4 and 10) in its lowest part towards the posterior, whence it puts forth a ligament 31 (f in the figure for ch. 1, Bk. 2) attaching the cartilaginous bone 32 of the tibia to the talus. In order to produce such a ligament, the anterior surface (l in figs. 1, 3, 9 33 ) of the lower epiphysis of the tibia, in its lowest part, also produces transversely a long, rough, uneven depression from which it puts forth a ligament [capsula articularis] that binds the neck of the talus [collum tali] (N in fig. 3, ch. 33) to the tibia. The posterior surface of this epiphysis is indented (m in figs. 2, 4, 10 and 1, 2, 3 in the 15th table of muscles) where it first puts forth the inner malleolus, and shows depressions which are covered by transverse ligaments [retinaculum musculorum flexorum] and allow the tendons of the muscles going this way to the foot to be carried safely without wandering from their depressions. These muscles are three in number (the first [m. tibialis posterior] is marked D, E in the 15th table, the second O [m. flexor hallucis longus], the third P [m. flexor digitorum longus]): the fifth of the muscles

that move the foot, and two that serve the flexion of the foot.
