Vascular Arrangement of the Rat Renal Glomerulus. A Scanning Electron Microscope Study of Corrosion Casts

Corrosion casts of the vascular beds of the rat kidney were prepared with methacrylic methyl ester resin, and sixty casts of normal glomeruli with single efferent arterioles were isolated. The isolated casts were microdissected in a warmed alcohol bath and observed under the scanning electron microscope. The same glomerular cast was observed from different directions and at different stages of mic…
