| Arias-Stella | Javier, Peruvian pathologist, *1924. See: Arias-Stella effect, Arias-Stella phenomenon, Arias-Stella reaction. (05 Mar 2000) |
| Arias-Stella effect | Focal, unusual, decidual changes in endometrial epithelium, consisting of intraluminal budding, and nuclear enlargement and hyperchromatism with cytoplasmic swelling and vacuolation; may be associated with ectopic or uterine pregnancy. Synonym: Arias-Stella effect, Arias-Stella reaction. (05 Mar 2000) |

| stella | A star or star-shaped figure. Origin: Mod. L. (05 Mar 2000) |
| apparatus suspensorius lentis | A series of delicate meridional fibres arising from the inner surface of the orbiculus ciliaris that run in bundles between, and in a very thin layer over, the ciliary processes; at the inner border of the corona, the fibres diverge into two groups that are attached to the capsule on the anterior and posterior surfaces of the lens close to the equator; the spaces between these two layers of fibres are filled with aqueous humor. Synonym: zonula ciliaris, apparatus suspensorius lentis, suspensory ligament of lens, Zinn's zonule. (05 Mar 2000) |
| axis lentis | A line connecting the anterior and posterior poles of the lens of the eye. Synonym: axis lentis. (05 Mar 2000) |
| capsula lentis | The capsule enclosing the lens of the eye. Synonym: capsula lentis, crystalline capsule, lenticular capsule, phacocyst. (05 Mar 2000) |
| capsula vasculosa lentis | In the embryo, the vascular mesenchymal capsule that invests the lens of the eye; the vessels of the dorsal part of the capsule are branches of the hyaloid artery; those of the ventral part are derived from the anterior ciliary arteries; normally all the vessels are atrophied by the end of the eighth month of intrauterine life. (05 Mar 2000) |
| radii lentis | 9 to 12 faint lines on the anterior and posterior surfaces of the lens that radiate from the poles toward the equator; they mark the lines along which the ends of lens fibres abut. Synonym: lens stars, lens sutures. (05 Mar 2000) |
| vortex lentis | One of the stellar figures on the surface of the lens of the eye. Synonym: vortex. (05 Mar 2000) |
| coloboma lentis | A segment of the lens equator devoid of zonular fibres, giving the appearance of a notch. (05 Mar 2000) |
| polus anterior lentis | The central point on the anterior surface of the lens of the eye. Synonym: polus anterior lentis. (05 Mar 2000) |
