The external diameter was calculated from the circumference of the external elastic lamella.

The fundamental unit of the aorta is the elastic lamella, which consists of smooth muscle and elastic matrix.

The medial layer of the aorta consist of concentric musculoelastic layers (the elastic lamella) in mammals.

The sections were digitized by tracing the contours of the lumen, the internal elastic lamella, and the external elastic lamella.

The internal elastic lamella of arteries is shown to form gaps prior to vessel dilatation in an experimental arteriovenous model in rabbit carotid artery [ 2 ] .

The internal elastic lamina or internal elastic lamella is a layer of elastic tissue that forms the outermost part of the tunica intima of blood vessels.
