Middle ear development: Genetics and disease
… mammalian middle ear is composed of three bony ossicles, the malleus, incus, and stapes that function to conduct sound from the external to the inner ear. Normal development of middle ear structures is integral for transduction of sound, defects resulting in conductive deafness. Mice are reliant …

Multiscale Structures and Mechanics of Biomineralized Lattices in Hexactinellid sponges and Echinoderms
… and microlattice scales) periodic structure: ossicle of starfish Protoreaster nodosus. This dissertation develops quantitatively the structural-mechanical/functional correlations in biomineralized cellular materials for bio-inspired material design. Four different species of Hexactinellid …

The study of a 3 3-dimentional structure of the congenital anomalous stape stapes compared with normal s stape stapes using Micro Micro-CT
… the internal structure of congenital anomalous ossicles. Recently, Micro CT scanning technology has been applied to analysis of skeletal structure. The data of normal ossicles and pathologic ossicle destructed by cholesteatoma were reported in our hospital. This study aims to compare the …

Mechanical Design of Selected Natural Ceramic Cellular Solids
… and the periodic open-cell structure in starfish ossicles, I systematically investigate the mechanical design strategies of these natural ceramic cellular solids. The three model systems are cuttlefish Sepia officinalis, sea urchin Heterocentrotus mammillatus, and starfish Protoreaster nodosus, …

The evolutionary transition from reptiles to mammals: analyses of body size reduction and separation of middle ear elements from the jaw
… joint and extended the middle ear into a three-ossicle chain. The articular and quadrate of the reptilian jaw have become the malleus and incus of the mammalian middle ear, respectively, adding to the pre-existing stapes. Another homologous element in this transition is the ectotympanic ring, …
