Fig. 3. Fetal Brain (6 month) Large Superficial Arteries

A photograph of a 6-months old fetal brain, with the large superficial arteries injected, and the brain cleared by the Spalteholz technique.

Arrows 1 and 2 indicate anastomoses between large branches of the anterior cerebral arteries and the middle cerebral arteries.

Arrows 3 and 4 point out anastomoses between the posterior cerebral and the middle cerebral arteries. These large superficial anastomoses can be seen clearly only before the development of the gyri and sulci.
