dc.description.abstract[ENG] Collection of micrographs on the organisation of muscular arteries, arterioles, and capillaries in paraffin sections and epoxy, semi-thin sections. Samples from rats and other species. In muscular arteries, smooth muscle cells in the tunica media are shown. Collagen fibres can be seen in the tunica adventitia. This collection complements the micrographs published by Dr Elena Sagristà i Mateo https://diposit.ub.edu/dspace/browse?type=author&value=Sagrist%C3%A0+i+Mateo%2C+Elenaca
dc.description.abstract[CAT] Col·lecció de micrografies de l'organització de les artèries musculars, arterioles i capil·lars en talls de parafina i talls semifins de resina epoxi. Mostres de rata i altres espècies. En les artèries musculars s’observa la capa gruixuda de musculatura llisa de la túnica mitjana i les fibres de col·lagen de la túnica adventícia. Aquesta col·lecció complementa les micrografies publicades per la Dra. Elena Sagristà i Mateo https://diposit.ub.edu/dspace/browse?type=author&value=Sagrist%C3%A0+i+Mateo%2C+Elenaca

Descripció:
Muscular artery in deep regions of the rat tongue. In the tunica intima (ti) only the nuclei of endothelial cells are visible, protruding from the vessel surface. The tunica media (tm) is thicker than the tunica adventitia (ta). This vessel lies next to nerve branches (n) and runs between bundles of striated muscle (st). Paraffin section, hæmatoxylin-eosin stain.

Descripció:
Detail of a muscular artery wall in the rat tongue. The tunica intima (ti) consists of a simple squamous epithelium ─the endothelium─ with flattened cell nuclei (arrows) stained dark blue with hæmatoxylin. The tunica media (tm) contains smooth muscle cells with oval or elongated nuclei (nu, lighter blue). The tunica adventitia (ta) includes thick collagen fibres (arrowheads) stained pink with eosin, along with connective tissue cells (stained dark blue with hæmatoxylin), for example, fibroblasts. Paraffin section, hæmatoxylin-eosin stain.

Descripció:
Muscular arteries deep within the rat tongue. In van Gieson trichrome stain, collagen fibres (col) –and connective tissue, in general– appear dark pink, stained with acid fuchsin. Collagen fibres can be seen between striated muscle bundles (st, light brown) and around two arteries. In the larger artery (bottom), endothelial cell nuclei are seen in the tunica intima (ti). A thick tunica media (tm) of smooth muscle cells (in brown) is surrounded by the tunica adventitia (ta) rich in collagen fibres. In the small artery (top) the same tunicae can be recognised. Paraffin section, van Gieson trichrome. e, erythrocytes.
