Medium-sized arteries:
When examining a cross-section of a medium-sized artery such as the carotid or cardiac arteries, we observe the following layers from inside to outside:
1- Tunica intima:
It consists of a wavy lining composed of an endothelium blanket epithelium based on a layer under a thin, indented subendothelium blanket. It is composed of dissociated connective tissue and internal elastic membrane and is usually wavy and glowing.
2. Tunica media:
It consists mainly of smooth, circularly arranged muscle fibers that form many concentric circular layers. These muscle fibers may intersect with white, whites, fibrous fibers and fibrous scars, which are usually the name of the tunic.
3. Tunica adventitia:
It consists of dissociated connective tissue, concentrated in the inner part of it composed of external rubber membrane, which is also crisscrossed. The outer part contains small blood vessels, Vasa vasorum.
