(a) processus anterior, (b) processus lateralis. The head and neck are situated in the epitympanic recess; the processus lateralis and manubrium are fixed to the medial surface of the membrana tympani; while the processus anterior is directed for- wards towards the petro-tympanic fissure, to which, in the adult, it is connected by ligamentous fibres. The head, somewhat rounded, is smooth and convex above and in front, and presents, on its posterior surface, a facet for articulation with the body Recessus epitympanicus Body of incus Crus breve of incus Ligament of incu Chorda tympani nerve Eminentia pyramid- alis, with tendon of. m. stapedius issuing from it Superior ligament of malleus Head of malleus Anterior ligament of malleus Manubrium mallei Base of stape;. tensor tympani Fig. 715.

This facet is directed obliquely downwards and medialwards, and is more or less elliptical in form. It is constricted near the middle so as to resemble, somewhat, the figure 8; an oblique ridge, corresponding with the constriction, divides the facet into two parts—an upper and larger, directed backwards, and a lower and lesser, directed medialwards. Opposite the lower part of the constriction the inferior edo-e of th
