Each of its four major branches (Figs 1-30A and 1-37) supplies a sector of the retina between which there is no overlap, i.e. they are functional end-arteries. The superior and inferior temporal arteries curve above and below the macula and foveal region. Arteries pass over veins and ...
1.a blood vessel that conveys blood from the heart to any part of the body. 2.a main channel or highway, esp. of a connected system with many branches. [1350–1400; Middle English < Latinartēria< Greek artēría windpipe, artery] ...
ICAInternal Carotid ArteryAscends through base of skull to give rise to the anterior and middle cerebral arteries, and connect with posterior half of circle of Willis via posterior communicating artery MCAMiddle Cerebral ArteryTrifurcates into temporal, frontal, and parietal branches that supply most ...
The pathway of parasympathetic nerve fibers to cerebral vessels from the otic ganglion in the rat. It has previously been shown that the otic ganglion contributes to the of pial arteries in the with parasympathetic fibers, but the exact pathway from the ... N Suzuki,JE Hardebo - 《Journal ...
In the wider scheme of things, all the intraocular branches of the CRA are actually arterioles (as they don't possess an internal elastic lamina), but the term artery has been used to describe the afferent components of the retinal vasculature for well over a century (His, 1880). At what...
Later on the arteries may appear narrow even in the presence of hypoxia and hypotonia. The diminuition can go up to 40%. We assume that these results are of interest both for research in retrolental fibroplasia and in cerebral perfusion (many common factors in vasomotion of both systems)...
which are located on the terminal branches of each neuron’s axon, enable the neuron to come in contact with the bodies or the dendrites of other neurons and to transmit its activity to them unilaterally (the Bell-Magendie law). The diverse external and internal receptors have become specialize...
Functional transcanial Doppler ultrasound (fTCD) is a convenient approach to examine cerebral blood flow velocity (CBFV) in major cerebral arteries. In this study, the anterior cerebral artery (ACA) was insonated on both sides, that is, right ACA (R-ACA)
the interpeduncular perforating branches, several small branches from the precommunical part (P1 segment) of the posterior cerebral artery and the posterior communicating artery supplying the posterior medial part of the midbrain. Synonym(s): arteriae centrales posteromediales [TA], paramedian arterie...
Theretinal arteriesare thin, and emboli are occasionally seen in thecentral retinal arteryor its branches. Literature Si esta arteria está presente, la visión central se verá preservada incluso en caso de padecerse obstrucción dela arteria central de la retina. ...
