Posteriorligament of the incus (Fig. 35, b, b). The short process of the incus, coveredwith a thin layer of fibrous cartilage, leans on the saddle-shaped depressionof the posterior wall of the tympanic cavity, at the entrance to the mastoidprocess. Of the fibrous prolongations, which connect the short process withthe osseous wall, the fibrous bundle extending between the short process andthe exterior wall of the fissure is especially strongly developed. The attic or cupola of the tympanum is divided by the articulation of themalleus and incus into two parts. The one lying between the articulationand the external wall was described by me as the external attic. This isformed above by the ligamentum mallei superior and the fold of the incus,.
