Plate 2. The developmental alterations in the vascular system of the brain of the human embryo
By George L. Streeter. (five plates and twelve text-figures)
Right and left profile views of a wax-plate reconstruction of the main arteries and veins in a human embryo 4 mm. long (Carnegie Collection, No. 588). Enlarged about 40 diameters.
This stjige 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 aie 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 eapiUarj- plexus of the brain-wall is fed bv 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.
