The superior ligament of the malleus extends from the tegmen tympani to the head ofthe malleus. (Figs. 1252 and ) 2. The anterior ligament of the malleus is a strong, broad, fibrous band arising from theanterior part of the head and neck of the malleus. Some of its fibres are attached to the ante-rior end of the annulus tympanicus (spina tympanica major) and other fibres pass through theGlaserian fissure to become attached to the spine of the sphenoid. These fibres correspond to theremains of the embryonic process of Meckel of the malleus and envelop the processus Sup. ligament Head of malleusExternal lij^amentMem. flaccida orShrapnells membranePrussaks spaceNeck Short process Chorda tympani Tendon of tensortympani Handle artilageEpidermisMenibrana propria M\ico>is niemhraneMenibrana tensa .nulus tendinosus Frontal section passing through malleus and tympanic membraney 8.
