Plate 3. The developmental alterations in the vascular system of the brain of the human embryo

By George L. Streeter. (five plates and twelve text-figures)

ight and left profile views of a wax-plate reconstruction of the blood-vessels of the brain in a liuman embryo 11.5 mm. long (Carnegie Collection. No. 544). Enlarged about 14 diameters. The primary head-vein still constitutes the main drainage-channel of the head. The manner in which its tributaries tap the deep capillary sheet investing the brain is indicated over a small area of the cerebral hemisphere. A capillary mesh of that kind invests the entire central nervous system, but is not shown in the model.
