|---|---|
| afferent glomerular arteriole | A branch of an interlobular artery of the kidney that conveys blood to the glomerulus. Synonym: arteriola glomerularis afferens, vas afferens, afferent vessel. (05 Mar 2000) |
| arteriole | <anatomy> A minute artery, especially one that leads to a capillary. (17 Oct 1997) |
| capillary arteriole | A minute artery that terminates in a capillary. (05 Mar 2000) |
| superior macular arteriole | Origin, central artery of retina; distribution, upper part of macula. Synonym: arteriola macularis superior. (05 Mar 2000) |
| superior nasal arteriole of retina | 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) |
| superior temporal arteriole of retina | 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) |
| inferior macular arteriole | Origin, central artery of retina; distribution, inferior part of macula. Synonym: arteriola macularis inferior. (05 Mar 2000) |

| efferent glomerular arteriole | The vessel that carries blood from the glomerular capillary network to the capillary bed of the proximal convoluted tubule; collectively, these vessels constitute the renal portal system. Synonym: arteriola glomerularis efferens, vas efferens, efferent vessel. (05 Mar 2000) |
| all-trans-retinal | The orange retinaldehyde resulting from the action of light on the rhodopsin of the retina, which converts the 11-cis-retinal component of the rhodopsin to all-trans-retinal plus opsin. Synonym: trans-retinal, visual yellow. (05 Mar 2000) |
| blood-retinal barrier | Specialised nonfenestrated tightly-joined endothelial cells that form a transport barrier for certain substances between the retinal capillaries and the retinal tissue. (12 Dec 1998) |
| central retinal artery occlusion | <ophthalmology> The sudden blockage of the retinal artery with a blood clot that commonly leads to a painless but irreversible blindness in that eye. (12 Jan 1998) |
