Corrosion casts of young rabbit palatine mucosa angioarchitecture

The microvascular system arrangement of the palatine mucosa in young rabbits was studied using vascular corrosion casts. Specimens were obtained by injecting low viscosity resin. Superficial microvessels were observed mainly by scanning electron microscopy (SEM). The blood microvessels showed differing features in the areas considered palatine rugae, inter-rugal areas and posterior region of the palatine raphe. Larger vessels were noted in deeper layers. Several capillary loops were distributed all over the palatine rugal surface. In spite of being a young animal, the rabbit's palatine mucosa demonstrated a complex angioarchitecture.
