Artery, light micrograph


Rights Managed


Light microscopy of a small muscular artery showing evidence of branching. The artery wall shows a single smooth muscle component (tunica media, red nuclei) together with elastic fibres (purple stripes). The outer connective tissue layer (green) is called the tunica adventitia. Muscular arteries serve to distribute and maintain blood flow to organs and tissues using their smooth muscle and elasticity to control vessel diameter. Magnification x130 when printed at 10 cm height.
