How can you use “mesenteric” in a sentence? Here are some example sentences to help you improve your vocabulary:
The processes of arterial remodeling involve regulation of vascular cell dynamics and control of matrix synthesis and degradation [ 1 ] . Endothelial cell (EC) proliferation is observed in flow-induced arterial dilation [ 2 ] and in vessel luminal expansion in mesenteric arterial collaterals in the rat [ 3 ] . Smooth muscle cells (SMC) have also been shown to proliferate in the vessel dilatation remodeling [ 3 ] . In the meantime, extracellular matrix (ECM) is involved in a variety of remodeling processes [ 4 5 6 7 8 9 ] including flow-induced arterial dilation [ 10 ] . These observations indicate that cell proliferation and ECM accumulation are critically involved in vessel remodeling.
Differences in smooth muscle layer thickness, however, do not always satisfactorily explain why in some instances, including stimulation of postganglionic nerve terminals, veins are more responsive than corresponding arteries [ 3 4 5 6 ] . Although differences in the type and amount of neurotransmitters, receptor density and/or sensitivity for neurotransmitter action, or signal transduction mechanisms that couple membrane receptors to the contractile elements have been proposed to underlie the functional distinctions between capacitative and resistive regions of the mesenteric circulation, the possibility that mesenteric artery and vein convey distinct expression levels of contractile proteins has not been ruled out.
Ultrastructural details in vessel wall morphology were observed by electron microscopy of the canine mesenteric artery and vein.
From a structural point of view, mesenteric blood vessels comply with the general notion that arterial walls are thicker than venous walls from the same branches.
