Muscular artery SFLT
From WikiLectures
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

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 - wall layers (AZAN)
Description:
- 1 – artery lumen,
- 2 – tunica media,
- 3 – tunica adventicia
Muscular artery - overview (silver impregnation)

Muscular artery RF
Description:
- 1 – artery lumen,
- 2 – membrana elastica interna,

Muscular artery - wall layers (resorcin-fuchsin staining)
Description:
- 1 – artery lumen,
- 2 – membrana elastica interna,
- 3 – tunica media,

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)
