The outermost fibres of the tendon(Fig. 32) proceed to the capsular ligament and the ossiculumlenticulare. According to Zuckerkandl, adipose tissue is foundbetween the muscle fibres of the tensor and the stapedius. A direct communication exists in the new-born between the inferior partof the eminentia stapedii and the Fallopian canal; in the adult, one ormore long fissures are often found between the two. The nerve of thestapedius passes from the facial either through one of these fissures, or througha separate small aperture. The difference of opinion whether the motor elements of the nerve tothe tensor tympani, arising from the otic ganglion of Arnold, belong to the. gaf 11 Fig. 89.—View of the TympanicCavity after Eemoval of theTegmen Tympani. ha, Malleo-incudal articulation ; t, Muse,tens. tymp. ; s, Tendon of the muse,tens. tymp. passing across the tym-panum ; /, Nerv. facialis; g, Genunervi facialis ; n, Nerv. petros. ; a, Nerv. acusticus ; an, An-trum mast.
