Description of Plates I

The drawings for Plates I and II were prepared under the guidance and assistance of Mr. Max Brodel.

The reproductions shown. on these plates represent different views, in most cases lateral, front, and median, of seven selected models showing the membranous labyrinth and acoustic complex reconstructed from the following human embryos: No. 148, 4.3 mm.; No. *17, 6.6 mm.; No. 163, 9 mm:; No. 109, 11 mm.; No. 175, 13 mm.; No. 22, 20 mm.; Plate 2 - No. 86, 30 mm.


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.
