Abstract

Fragments of the common carotid arteries were collected from 8 goats that had succumbed to accidents. These samples underwent histological processing, involving fixation and embedding in paraffin. Sections, 5 µ in thickness, were then stained using the Trichrome Goldner method for overall assessment and Verhoeff staining for elastic tissue analysis. Upon using Trichrome Goldner staining, it was observed that goat carotid arteries exhibited a typical appearance of muscular arteries, with the thickest layer being the media, primarily composed of muscular components. Verhoeff staining further revealed a well-represented elastic tissue presence within the adventitia, exhibiting a distinct arrangement. Both staining methods indicated that goat common carotid arteries possess tunics comparable in thickness to muscular arteries, with a predominantly muscular media. However, the adventitia was notably distinguished by a significantly higher concentration of elastic tissue compared to typical muscular arteries. Consequently, with these findings, we propose classifying goat common carotid arteries as musculoelastic transitional arteries.
