Fig. 738. Typical auditory vesicle in a human embryo of 10.2 mm CRL

(Anatomical Collection in Basel.)

Section shows the back of the head in the region of the rhombencephalon (hindbrain). Inside the auditory vesicle is a cell surface that lies beside the developing neuroepithelium medial wall, where later the utricle and sacculus will develop, in a multilayered epithelium. The same situation also occurs several times in the stratified on cochlear duct. Where no developing neuroepithelium occurs there is only a thin epithelia.

Fig. 738, Durchschnitt der Vesicula auditiva bei einem menschlichen Embryo

von 10,2 mm Nackensteifilänge.

(Anatomische Sammlung in Basel.)


Durchschnitt durch den Hinterkopf im Bereich des Rhombencephalon. Im Innern des Hörbläschens befindet sich ein Zellenbelag und zwar nimmt die Neuroepithelanlage die ganze mediale Wand ein, dort wo später der Utriculus und Sacculus sich herausbilden, kennthch an einem vielschichtigen Epithel. Dieselbe mehrfach geschichtete Lage tritt auch im Ductus cochlearis auf. An den Stellen, wo keine Neuroepithelien auftreten, ist die Lage der Epithelien dünn.
