From Embryology
This Embryology category shows pages and images that relate to the Carnegie Collection Embryo No.8963. This 22 somite embryo was a tubal pregnancy originally classified as University of Chicago No. H951. Described by Wen (1928)[1] with particular reference to the neural, renal, vascular systems.
- "Embryo H951 (fig. 1, A) was obtained from Drs. E. L. Whitney and J. T. Rocks, of Walla Walla, Washington. “The uterus was removed for fibrosis on the 13th day after the day on which menstruation was expected to begin,” opened and fixed in ‘4%’ formalin. No further clinical information could be obtained. The embryo was mordanted in aqueous chrom—sublimate, slowly dehydrated, double embedded in celloidin and paraffin, cut into transverse sections, and stained with iron hematoxylin (all but one slide being counterstained with eosin). During the mounting, five sections were slightly distorted and, unfortunately, three sections lost, so it is not easy to follow the series at the region between the 4th to 5th somites. A plaster model of the head region (figs. 2, 3), a wax model of the entire embryo, and one of the anterior portion of the central nervous system with the ventral pharyngeal wall were made from serial photomicrographs at the magnification of 150 times. Two other plaster models, one of the entire embryo and one of the head region alone showing the anatomy therewith, were made by O. O. Heard. Histologically, this specimen is in excellent condition."[1]
Carnegie stage 11 - Week 4, 23 - 26 days, GA - week 6, 4.0 mm GL, Somite Number 17. Conceptus - 23.1 x 10.4 x circ.11 mm.
The embryo was sectioned into 336 sections at 10 µm.
