Description of Plates II

The reproductions shown on this plate represents different views, lateral, front, and median, of a selected model showing the membranous labyrinth and acoustic complex reconstructed from the following human embryo No. 86, 30 mm. The drawings for Plates I and II were prepared under the guidance and assistance of Mr. Max Brodel.

The colors, yellow and red, are used to indicate respectively the cochlear and vestibular divisions, and in general nerve flbers can be distinguished from ganglion cell masses by their lighter tone. The pictures represent a magniflcation of 25 diams.

The following abbreviations are used:

  • absorpt. focus - area of wall where absorption is complete.
  • amp. - ampulla membranacea.
  • crus - crus commune.
  • c.sc.lat. - ductus semicircularis lateralis.
  • c. sc. post. - ductus semicircularis posterior.
  • c. sc. sup. - ductus semicircularis superior.
  • coch.orcochlea - ductus cochlearis.
  • duct. endolymph. - ductus endolymphaticus.
  • d. reuniens - ductus reuniens Henseni.
  • endol. or endolymph. - appendix endolymphaticus.
  • rec. utr. - recessus utriculi.
  • sacc. - sacculus.
  • sac. endol. - saccus endolymphaticus.
  • sinus utr. lat. - sinus utriculi lateralis.
  • utric. - utriculus.
  • vestib.p. - vestibular pouch.


Carnegie Embryo 86 has been classified as Carnegie stage 23 occurring during Week 8, GA week 10.
