| conjunctival fornix | The space formed by the junction of the bulbar and palpebral portions of the conjunctiva, that of the upper lid being the fornix conjunctivae superior and that of the lower lid the fornix conjunctivae inferior. Synonym: fornix conjunctivae, conjunctival cul-de-sac, retrotarsal fold. (05 Mar 2000) |
| conjunctival glands | Clusters of mucous cells in the conjunctival epithelium, most numerous on the bulbar conjunctiva. Synonym: glandulae conjunctivales, Terson's glands. (05 Mar 2000) |
| conjunctival reflex | Closure of the eyes in response to irritation of the conjunctiva. (05 Mar 2000) |
| conjunctival ring | A narrow ring at the junction of the periphery of the cornea with the conjunctiva. Synonym: annulus conjunctivae. (05 Mar 2000) |
| conjunctival sac | The space bound by the conjunctival membrane between the palpebral and bulbar conjunctiva; into which the lacrimal fluid is secreted; it opens anteriorly between the eyelids. Synonym: saccus conjunctivae. (05 Mar 2000) |
| conjunctival varix | A varicose condition of the veins of the conjunctiva. Synonym: conjunctival varix. Origin: L. Dim. Of varix (05 Mar 2000) |
| conjunctival veins | The veins of the conjunctiva which drain primarily to the ophthalmic veins. Synonym: venae conjunctivales. (05 Mar 2000) |
| posterior conjunctival artery | <anatomy, artery> One of a series of branches from the arterial arches of the upper and lower eyelids that supplies the conjunctiva. Synonym: arteria conjunctivalis posterior, conjunctival arteries. (05 Mar 2000) |
| semilunar conjunctival fold | The semilunar fold formed by the palpebral conjunctiva at the medial angle of the eye, a fold of the conjunctival mucous membrane found in many animals; normally partially hidden in the medial canthus of the eye when at rest, it may be extended to cover part or all of the cornea in a winking-like action to clean the cornea, as in birds. Synonym: membrana nictitans, nictitating membrane, palpebra III, palpebra tertia, third eyelid. Synonym: plica lunata, plica semilunaris of eye, semilunar conjunctival fold. (05 Mar 2000) |
| A layer | <molecular biology> Right handed double helical DNA with approximately 11 residues per turn. Planes of base pairs in the helix are tilted 20 deg away from perpendicular to the axis of the helix. Formed from B DNA by dehydration. (18 Nov 1997) |
| ameloblastic layer | The internal layer of the enamel organ. Synonym: enamel layer. (05 Mar 2000) |
| anterior elastic layer | A transparent homogeneous acellular layer, 6 to 9 um thick, lying between the basal lamina of the outer layer of stratified epithelium and the substantia propria of the cornea; considered to be a basement membrane. Synonym: lamina limitans anterior corneae, anterior elastic layer, Bowman's membrane, lamina elastica anterior, limiting layers of cornea. (05 Mar 2000) |
| anterior layer of rectus abdominis sheath | The portion of the rectus sheath that lies anterior to the muscle, consisting in its upper two-thirds of contributions from the aponeuroses of the external and internal oblique muscles, and in its lower third (below the arcuralt line) of contributions from the aponeuroses of all three muscles of the anterolateral abdominal wall. Synonym: lamina anterior vaginae musculi recti abdominis. (05 Mar 2000) |
| anterior limiting layer of cornea | A transparent homogeneous acellular layer, 6 to 9 um thick, lying between the basal lamina of the outer layer of stratified epithelium and the substantia propria of the cornea; considered to be a basement membrane. Synonym: lamina limitans anterior corneae, anterior elastic layer, Bowman's membrane, lamina elastica anterior, limiting layers of cornea. (05 Mar 2000) |
