arteriola nasalis retinae inferior |
The branch of the central artery of the retina that supplies the lower medial, or nasal, part of the retina. Synonym: arteriola nasalis retinae inferior. (05 Mar 2000) |
|---|---|
arteriola nasalis retinae superior |
The branch of the central artery of the retina that passes to the upper medial, or nasal, part of the retina. Synonym: arteriola nasalis retinae superior. (05 Mar 2000) |
arteriola temporalis retinae inferior |
The branch of the central artery of the retina that passes laterally below the macula to supply the lower lateral or temporal part of the retina. Synonym: arteriola temporalis retinae inferior. (05 Mar 2000) |
arteriola temporalis retinae superior |
The branch of the central artery of the retina that passes laterally above the macula to supply the upper lateral or temporal part of the retina. Synonym: arteriola temporalis retinae superior. (05 Mar 2000) |
arteriolae rectae |
Straight vessels into which the efferent arteriole of the juxtamedullary glomeruli breaks up; they form a leash of vessels which, arising at the bases of the pyramids, run through the renal medulla toward the apex of each pyramid, then reverse direction in a hairpin turn, and run straight back again toward the base of the pyramid as venae rectae. Synonym: straight seminiferous tubule. Synonym: arteriolae rectae. (05 Mar 2000) |
arteriolar |
<anatomy> Pertaining to or resembling arterioles. (18 Nov 1997) |
arteriolar nephrosclerosis |
<nephrology> Refers to the destructive changes that occur in the blood vessels of the kidney due to severe hypertension (malignant hypertension). Prolonged hypertension can result in renal failure. (17 Oct 1997) |
arteriolar network |
A vascular network formed by anastomoses between minute arteries just before they become capillaries. Synonym: rete arteriosum. (05 Mar 2000) |
arteriolar sclerosis |
<cardiology, disease> Sclerosis and thickening of the walls of the smaller arteries (arterioles). Hyaline arteriolosclerosis, in which there is homogeneous pink hyaline thickening of the arteriolar walls, is associated with benign nephrosclerosis. Hyperplastic arteriolosclerosis, in which there is a concentric thickening with progressive narrowing of the lumina may be associated with malignant hypertension, nephrosclerosis and scleroderma. (17 Oct 1997) |
arteriole |
<anatomy> A minute artery, especially one that leads to a capillary. (17 Oct 1997) |
arterioles |
The smallest divisions of the arteries located between the muscular arteries and the capillaries. (12 Dec 1998) |
arteriolith |
A calcareous deposit in an arterial wall or thrombus. Origin: L. Arteria, artery, + G. Lithos, a stone (05 Mar 2000) |
arteriolitis |
Inflammation of the wall of the arterioles. Origin: L. Arteriola, arteriole, + G. -itis, inflammation (05 Mar 2000) |
arteriolo- |
The arterioles. Origin: Modern L. Arteriola, arteriole (05 Mar 2000) |
arteriology |
<study> That part of anatomy which treats of arteries. (04 Mar 1998) |
