From Embryology
This Embryology category shows pages and images that relate to the Carnegie Collection Embryo No.8964. This 23 somite embryo was a tubal pregnancy originally classified as University of Chicago No. H984. Described by Wen (1928)[1] with particular reference to the neural, renal, vascular systems.
Carnegie stage 12 - Week 4, 26 - 30 days, GA - week 6, 2.8 - 2.9 mm, Somite Number 23. 26.7 x 22.7 x 17.3 mm.
The embryo was sectioned into 349 sections at 8 µ transverse sections.
- Embryo H984 (fig. 1, C) was donated to the collection by Drs. E. W. Rawson and B. H. Foreman of Tacoma, Washington. It came from an abortion and after remaining in weak formalin for several years it was mordanted in aqueous chrom-sublimate, embedded in paraffin, cut into transverse sections, and stained with iron hematoxylin. The material was macerated and considerable shrinkage and cracking occurred during dehydration. Histological differentiation is poor. Serial photomicrographs at the magnification of 125 times were made, but no model has been attempted.[1]
