What is the tissue found in the wall of the aorta?

Question

Is it elasic connective tissue?

Answer 1

Yes, this topic will help you a lot:
Aorta, human - H&E , elastin & van Gieson
The thin endothelial lining of the aorta corresponds to that of other vessels. The flattened cells are easily damaged during preparation and it may be difficult to identify the endothelium. The subendothelial layer of connective tissue is characterised by a lower density of cells, i.e. fewer nuclei, a fibrous appearance of the tissue and the absence of well-defined elastic layers. Because the lamellae of elastic fibers diffract light differently from the remaining tissues they should also be visible in H&E stained sections. Elastic lamellae become visible in the tunica media. The majority of cells in the tunica media are smooth muscle cells. Smooth muscle cells and collagen fibres are found between the layers of elastic fibres. If you scan the periphery of the aorta you may find small blood vessels, the vasa vasorum, in the tunica adventitia and penetrating into the outer part of the tunica media.
