title: [Contribution to the morphological knowledge of the articulations of the human tympanic ossicular chain].
abstract: The structure of human tympanic bones and their articulations was studied. Martin's trichrome stain of serial sections revealed the transmission paths of force lines based on bone lamellae density and acid fuchsin staining, which disclosed functional "critical points" (mechanical solicitation). This study contributed basic knowledge and a morphological and functional classification of the incudomalieotar and incudostapedial joints. The incudomalieolar joint was confirmed as a "riding saddle" but the incudostapedial joint as a "spheroid joint" was questioned. Information on capsule structure the meniscus and articular cartilage of the incudomalleolar joint is given.
