Title: Arterial constrictors: penile - coronary vessels (human)
Description:
(A): Detailed in (B). Arterial constrictor e.g. helicine artery (penis), elastica (Masson), adult. Few intimal cross-sectioned smooth muscle cells (SMC) (1) surrounded by dark-stained elastic fragments and a discontinuous internal elastic membrane (IEL), a media (2) and a fine-fibrillary collagenous adventitia (3) followed by an outer layer of 3-D woven coarse collagen fibers with dense-stained short elastic fibers (4) close to cross-sectioned smooth muscle bundles (5) of the trabecula (penile cavernous body). (6) Cross-sectioned nerve bundles.
(B): Arterial constrictor e.g. internal pudendal artery, elastica (Masson), adult. This artery has intimal cushion (1), a media (2) and adventitia (3) with vasa vasorum (*) closely adhered to dense collagenous tissue with long elastic fibers (4). Generally supplying arteries within erectile tissue (penile corpus spongiosum) are extra supported by a band of dense collagen tissue and dispersed elastic fibers to create an elastic medium against increased pressure during contractions.
(C-D): Survey and detail of arterial constrictors e.g. coronary vessels, reticulin-Weigert, young adult. Three coronary arteries (*) with intimal cushions (1) and reinforced with smooth muscle cells in the intima and media. Media contains circular and longitudinal smooth muscle bundles extended in the adventitia, coronary vein (v). The constrictor arteries in the heart are constructed similarly as in the penis in (A, B).
(E): Large descending coronary artery (longitudinal section), HE, autopsy, senium. The intima (1) is exceptional thickened with longitudinal SMC. The media (2) contains circular muscle fibers. (3) Adventitia.
Background: Arterial constrictors are specialized arteries with muscular cushions in the intima to regulate the blood flow. These constrictors are present in areas with regular blood pressure fluctuation such as in the heart muscle (systole-diastole), penile tissue (intumescence-detumescence).
