Figures 7, 8. and 9. Three stages in the formation of the sagittal plexus
Three stages in the formation of the sagittal plexus showing its asymmetrical character and its conversion into the superior sagittal sinus. Draining into it from below is the drainage-channel from the chorioidal bodies that is later known as the straight sinus. The channels marked x are interpreted as undergoing retrogression, being replaced by more caudal channels. Large dural channels do not persist in the areas covering the cerebral hemispheres; they are found only in the loose embryonic tissue filling the spaces and fissures that lie between the different subdivsions of the brain.
- Figure 7 is a vertex view of a human embryo 13.8 mm long (Carnegie Collection. No. 940).
- Figure 8 is a vertex view of an embryo 20 mm long (Carnegie Collection, No. 349).
- Figure 9 is a drawing of an injected and cleared specimen 54 mm long (Carnegie Collection, No. 458) reversed.

Pages where the terms "Historic" (textbooks, papers, people, recommendations) appear on this site, and sections within pages where this disclaimer appears, indicate that the content and scientific understanding are specific to the time of publication. This means that while some scientific descriptions are still accurate, the terminology and interpretation of the developmental mechanisms reflect the understanding at the time of original publication and those of the preceding periods, these terms, interpretations and recommendations may not reflect our current scientific understanding.
