Figure 24. Right profile views of a wax-plate reconstruction of the blood-vessels of the brain in a human embryo 11.5 mm long

Carnegie Collection Embryo No. 544 Carnegie stage 17 Week 6 on the basis of CRL and the presence of digital rays.

Right and left profile views of a wax-plate reconstruction of the blood-vessels of the brain in a human embryo 11.5 mm long. Enlarged about 14 diameters. Plate 3 - Both views

  • 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.
