摘要
外耳、颞骨和中耳裂的发育涉及外胚层、中胚层和内胚层的相互作用。源自神经外胚层耳囊的特殊感觉受体(Friedmann 1968)被软骨囊发育的间质所包围(Baxter 1953, Hamilton et al. 1972, Warwick & Williams 1973)。该囊位于咽鼓室内隐窝内侧。Kanagasuntheram(1967)最近的研究表明，鼓室的衬里及其延伸部分仅来自第一咽袋。第一软骨的远端
The development of the external ear, temporal bone and middle ear cleft involves interactions between ectoderm, mesoderm and endoderm. The special sensory receptors derived from the neuroectodermal otic vesicle (Friedmann 1968) are surrounded by mesenchyme in which the cartilaginous otic capsule develops (Baxter 1953, Hamilton et al. 1972, Warwick & Williams 1973).This capsule lies medial to the endodermal pharyngotympanic recess. Recent work by Kanagasuntheram (1967) indicates that the lining of the tympanum and its extensions is derived only from the first pharyngeal pouch. The distal ends of the cartilages of the first
