Fig. 20-2. Head Superficial Vascular Plexus - Stages 20-23
Composite drawing showing the edge of the superficial vascular plexus in the head at stages 20-23. A subcutaneous capillary plexus that spreads upward toward the vertex of the head is a conspicuous feature of specimens measuring from about 20-24 mm in length.
The transition from vascular to avascular mesoderm is more gradual in earlier stages and becomes more abrupt later.
Numbers refer to specific Carnegie embryos.
