| ectopia vesicae | A congenital gap in the anterior wall of the bladder and the abdominal wall in front of it, the posterior wall of the bladder being exposed. Synonym: ectopia vesicae. (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) |
| polus posterior lentis | The central point on the posterior surface of the lens. Synonym: polus posterior lentis. (05 Mar 2000) |
| cortex lentis | The softer, more superficial part of the lens of the eye that encloses the central part or nucleus; its refractive power is less than that of the nucleus. Synonym: cortex lentis. (05 Mar 2000) |
| stella lentis hyaloidea | The posterior pole of the lens. See: radii lentis. (05 Mar 2000) |
| stella lentis iridica | The anterior pole of the lens. See: radii lentis. (05 Mar 2000) |
| substantia lentis | That which constitutes the lens of the eye, composed of a nucleus and a cortex and covered by an epithelium. Synonym: substantia lentis. (05 Mar 2000) |
| nucleus lentis | The core or inner dense portion of the lens of the eye. Synonym: nucleus of lens. (05 Mar 2000) |
