Muscular artery SFLT



Name: Muscular artery – overview (HE)



Description:
 * 1 – artery lumen
 * 2 – intima and membrana elastica interna
 * 3 – tunica media
 * 4 – membrana elastica externa
 * 5 - other muscle-type artery,
 * 6 - vein,
 * 7 - peripheral nerve (autonomic nervous system),
 * 8 – pancreatic parenchyma - light circles are the islets of Langerhans (endocrine part of the pancreas), dark circles are serous acini (exocrine part of the pancreas),
 * 9 – adipose tissue,
 * 10 – muscular artery branches into arteries of smaller caliber, which they run in fibrous septa through the parenchyma



Muscular artery - wall layers (HE staining)



Description:
 * 1 – artery lumen,
 * 2 – membrana elastica interna,
 * 3 – tunica media artery,
 * 4 – membrana elastica externa,
 * 5 – nerve on cross section,
 * 6 – another artery of muscular type and smaller caliber



 Muscular artery – overview (AZAN) 



Description:
 * 1 – arterial lumen,
 * 2 – membrana elastica interna,
 * m – tunica media,
 * a – tunica adventicia



 Muscular artery - wall layers (AZAN)



Description:
 * 1 – artery lumen,
 * 2 – tunica media,
 * 3 – tunica adventicia



 Muscular artery - overview (silver impregnation) 



Description:
 * 1 – artery lumen,
 * 2 – membrana elastica interna,
 * 3 – tunica media,
 * 4 – tunica adventitia



Muscular artery RF 



Description:
 * 1 – artery lumen,
 * 2 – membrana elastica interna,
 * 3 – tunica media,
 * 4 – tunica adventitia



 Muscular artery - wall layers (resorcin-fuchsin staining) 



Description:
 * 1 – artery lumen,
 * 2 – membrana elastica interna,
 * 3 – tunica media,
 * 4 – membrana elastica externa,
 * 5 - tunica adventitia



 Artery and vein - comparison of vessels of the same caliber (Weigert van Gieson staining) 



Description:
 * A – artery, V – vein,
 * m - tunica media, a – tunica adventitia,
 * tunica adventitia tissue of both vessels passes into the surrounding tissue,
 * rich in fat cells (T)



Note: the Weigert van Gieson method distinguishes the ligament in the tunica adventitia (red) from the tunica media (yellow)
