Imprints on the Blood Vessel Cast of the Inner Ear

Abstract

In the present study, imprints on the corrosion casts of blood vessel were observed under a scanning electron microscope. The results obtained were as follows
(1) In the artery and arteriole, their imprints were long, regular spindle-shaped, and their long axes ran almost in parallel to the blood flow.
(2) In the vein, surface of the corrosion cast was smooth and oval-shaped nuclear subsidences were observed.
(3) In the capillary, surface of the corrosion cast was smooth and nuclear imprints were not observed.
(4) In the cochlear plexus capillary, fenestrations of the endothelial cells were observed.
