The architecture of the choriocapillaris at the posterior pole
Abstract:
The afferent and efferent vessels as well as the choriocapillaris in the human posterior pole, studied in flat preparations, paraffin sections, and Epon sections, formed relatively discrete units of organization which we called lobules. A lobule is a segment of the choriocapillaris supplied centrally by a precapillary arteriole and demarcated peripherally by a ring of postcapillary venules. Observations on the choroidal phase of fundus fluorescein angiography indicated that blood entering a lobule did not intermingle with blood from adjoining lobules. The choriocapillaris in the posterior pole of the human eye, with its supplying and draining vessels, appeared as a mosaic of adjoining lobules that function independently.

The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
