| processus ciliaris | One of the radiating pigmented ridges, usually seventy in number, on the inner surface of the ciliary body, increasing in thickness as they advance from the orbiculus ciliaris to the external border of the iris; these, together with the folds (plicae) in the furrows between them, constitute the corona ciliaris. Synonym: processus ciliaris. (05 Mar 2000) |

| nervus ciliaris brevis | <anatomy, nerve> One of a number of branches of the ciliary ganglion, supplying the ciliary muscles, iris, and tunics of the eyeball. Synonym: nervus ciliaris brevis. (05 Mar 2000) |
| nervus ciliaris longus | <anatomy, nerve> One of two or three branches of the nasociliary nerve, which by-pass the ciliary ganglion, supplying post-synaptic sympathetic fibres for the dilator pupillae muscle and sensory fibres for the ciliary muscles, iris, and cornea. Synonym: nervus ciliaris longus. (05 Mar 2000) |
| stratum pigmenti corporis ciliaris | The continuation of the pigment layer of the retina onto the posterior aspect of the ciliary body. Synonym: pigmented layer of ciliary body. (05 Mar 2000) |
| orbiculus ciliaris | The darkly pigmented posterior zone of the ciliary body continuous with the retina at the ora serrata. Synonym: ciliary disk, ciliary ring, pars plana. Origin: Mod. L. (05 Mar 2000) |
| tylosis ciliaris | Thickening of the tarsal border of the eyelid. Synonym: tylosis ciliaris. Origin: pachy-+ G. Blepharon, eyelid (05 Mar 2000) |
| zona ciliaris | The outer, wider zone of the anterior surface of the iris, separated from the pupillary zone by the collarette. Synonym: zona ciliaris. (05 Mar 2000) |
| zonula ciliaris | 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) |
| lamina basalis corporis ciliaris | The inner layer of the ciliary body, continuous with the basal layer of the choroid and supporting the pigment epithelium of the ciliary retina. Synonym: lamina basalis corporis ciliaris, basal layer of ciliary body. (05 Mar 2000) |
| acne | <dermatology> An inflammatory disease of the pilosebaceous unit, the specific type usually being indicated by a modifying term, frequently used alone to designate common acne or acne vulgaris. Origin: possibly Gr. Akm = a point or achn = chaff (15 Nov 1997) |
| acne albida | Acne caused by milia. (05 Mar 2000) |
| acne artificialis | Acne produced by external irritants, such as tar (chloracne), or drugs internally administered, such as iodides or bromides. Synonym: acne venenata. (05 Mar 2000) |
| acne bacillus | A bacteria isolated from normal skin, intestinal contents, wounds, blood, pus, and soft tissue abscesses. It is a common contaminant of clinical specimens, presumably from the skin of patients or attendants. (12 Dec 1998) |
| acne cachecticorum | Acne occurring in persons who have a debilitating constitutional disease; characterised by large, soft, purulent, ulcerative, cystic, and scarred lesions. (05 Mar 2000) |
| acne conglobata | Severe cystic acne, characterised by cystic lesion, abscesses, communicating sinuses, and thickened, nodular scars; usually sparing the face. (05 Mar 2000) |
