| pupillary distance | The distance between the centre of each pupil; the major reference points in measuring for fitting of spectacle frames and lenses. (05 Mar 2000) |
|---|---|
| pupillary functions, abnormal | Conditions in which the pupil does not react normally to dilation and constriction. Signs of pupillary abnormalities originate from the pupil's shape, position, and response to stimulation. (12 Dec 1998) |
| pupillary light-near dissociation | A stronger near pupil response than light response; due to weak pupillomotor input, Argyll Robertson pupil, dorsal midbrain syndrome, or to misdirection of ciliary muscle fibres into the iris sphincter. Synonym: light-near dissociation. (05 Mar 2000) |
| pupillary margin of iris | The inner border of the iris that forms the edge of the pupil. Synonym: margo pupillaris iridis, pupillary margin of iris. (05 Mar 2000) |
| pupillary reflex | Change in diameter of the pupil as a reflex response to any type of stimulus; e.g., constriction caused by light. Synonym: light reflex. (05 Mar 2000) |
| pupillary ruff | The dark-brown, wrinkled rim of the normal pupil. This is the posterior pigment epithelium of the iris showing itself at the pupillary margin. (05 Mar 2000) |
| pupillary-skin reflex | Dilation of the pupil following scratching of the skin of the neck. Synonym: ciliospinal reflex, cutaneous pupil reflex, cutaneous-pupillary reflex, skin-pupillary reflex. (05 Mar 2000) |
| pupillary zone | The central region of the anterior surface of the iris located between the collarette and the pupillary margin. Synonym: zona pupillaris. (05 Mar 2000) |
| skin-pupillary reflex | Dilation of the pupil following scratching of the skin of the neck. Synonym: ciliospinal reflex, cutaneous pupil reflex, cutaneous-pupillary reflex, skin-pupillary reflex. (05 Mar 2000) |
| indirect pupillary reaction | Contraction of the pupil of the fellow eye in consensus with the pupil of the illuminated eye. Synonym: consensual light reflex, indirect pupillary reaction. (05 Mar 2000) |
| orbicularis pupillary reflex | A constriction of both pupils when an effort is made to close eyelids forcibly held apart. A variant of the pupil response to near vision. Synonym: Galassi's pupillary phenomenon, Gifford's reflex, lid-closure reaction, orbicularis phenomenon, orbicularis pupillary reflex, Piltz sign, Westphal's pupillary reflex, Westphal-Piltz phenomenon. (05 Mar 2000) |
| adamantine membrane | The primary enamel cuticle, consisting of two extremely thin layers (the inner one clear and structureless, the outer one cellular), covering the entire crown of newly erupted teeth and subsequently abraded by mastication; it is evident microscopically as an amorphous material between the attachment epithelium and the tooth. Synonym: cuticula dentis, adamantine membrane, dental cuticle, membrana adamantina, Nasmyth's cuticle, Nasmyth's membrane, skin of teeth. (05 Mar 2000) |
| allantoid membrane | An embryonic diverticulum of the hindgut of reptiles, birds, and mammals; in man its blood vessels give rise to those of the umbilical cord. (12 Dec 1998) |
| alveolocapillary membrane | The pulmonary diffusion barrier. (05 Mar 2000) |
| alveolodental membrane | <anatomy> Fibrous connective tissue surrounding the root of a tooth that separates it from and attaches it to the alveolar bone. (12 Dec 1998) |
