Plate 2. The developmental alterations in the vascular system of the brain of the human embryo

Carnegie Collection, No. 588

Right and left profile views of a wax-plate reconstruction of the main arteries and veins in a human embryo 4 mm long.

Enlarged about 40 diameters.

  • This stage illustrates the character of the first type of the circulation of the head and its relation to the other blood-vessels of the body.
  • The primary head-vein and its tributaries which form the main drainage-channels of the head as shown in blue.
  • These communicate by anastomosing loops with the capillary plexus everywhere investing the brain-wall, only patches of which are shown in the model.
  • The capillary plexus of the brain-wall is fed by arterial feeders, the stumps of which, as shown in the model, arise from the aortic system.
  • The trunk that persists as the internal carotid artery is already quite definite.
