title: [The vascularisation of the periorbita].
abstract: 1. The periorbita is extensively vascularised from the side of the bone and the orbita. The vessels are interconnected so that the periost is not vascular boder area. 2. In the periorbita of the adult there is a dense capillary plexus which is less close-meshed on the inside. 3. Meandrian arteries and vascular loops exceptionally as long as 6 mm were found in the inner layers of the periorbita and in the adjacent layers of the fat connective tissue. 4. Flat membranes of fat connective tissue which are connected with the inner layer of the periorbita by long vascular streaks about on the inner surfaces of the periorbita. 5. On the outer surface of the periorbita venules 40 to 60 mum wide were found entering the periorbital bone. In the fissures area further meandering venules and venes were found which open in the cavernous sinus (in addition to the Vv. ophthalmicae) or enter the bordering bone. 6. N. and A. infraorbitalis run outside of the periorbita. 7. The nerves leave the periorbita by special channels and run through near and husk-like processes of the periorbita which accompany them up to the outer periost. In the bone they five off bone vessels.
