شعيرة شريانية (بالإنجليزية: Metarteriole) هي في دوران الأوعية الدقيقة ويربط بين الشريينات والشعيرات الدموية. (ar) A metarteriole is a short microvessel in the microcirculation that links arterioles and capillaries. Instead of a continuous tunica media, they have individual smooth muscle cells placed a short distance apart, each forming a precapillary sphincter that encircles the entrance to that capillary bed. Constriction of these sphincters reduces or shuts off blood flow through their respective capillary beds. This allows the blood to be diverted to elsewhere in the body. Metarterioles exist in the mesenteric microcirculation, and the name was originally conceived only to define the "thoroughfare channels " between arterioles and venules. In recent times the term has often been used instead to describe the smallest arterioles directly prior to the capillaries. (en) Metarteríola é uma ramificação direta da arteríola. Esse tipo de vaso capilar é envolto por músculo liso, que se contrai regulando a circulação nesses vasos quando não é necessária ocorrência de fluxo sanguíneo em toda rede de metarteríolas em determinado momento. Esses vasos ligam as arteríolas aos capilares. (pt) Metaarteriola, (naczynie przedwłosowate, łac. vasa precapillaria s. metaarteriolae) − naczynie krwionośne znajdujące się między najmniejszymi tętnicami (arteriole) a naczyniami włosowatymi. Od naczyń włosowatych różnią się występowaniem w swoich ścianach warstwy mięśni gładkich. (pl) |
