| 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) |
|---|---|
| anterior epithelium of cornea | The stratified squamous epithelium covering the outer surface of the cornea; it is smooth, consists usually of five layers of cells, and contains numerous free nerve endings. Synonym: epithelium anterius corneae. (05 Mar 2000) |
| Barrett's epithelium | Columnar oesophageal epithelium seen in Barrett's syndrome. (05 Mar 2000) |
| germinal epithelium | A cuboidal layer of peritoneal epithelium covering the gonads, once thought to be the source of germ cells. (05 Mar 2000) |
| reduced enamel epithelium | The several layers of the enamel organ remaining on the enamel surface after formation of enamel is completed. Synonym: reduced enamel epithelium. (05 Mar 2000) |
| gingival epithelium | A stratified squamous epithelium that undergoes some degree of keratinization and covers the free and attached gingiva. (05 Mar 2000) |
| glandular epithelium | Epithelium composed of secretory cells. (05 Mar 2000) |
| pavement epithelium | Epithelium composed of a single layer of flattened scalelike cells, such as mesothelium, endothelium, and that in the pulmonary alveoli. Synonym: pavement epithelium. (05 Mar 2000) |
| respiratory epithelium | The pseudostratified ciliated epithelium that lines the conducting portion of the airway, including part of the nasal cavity and larynx, the trachea, and bronchi. (05 Mar 2000) |
| mesenchymal epithelium | The flat epithelium derived from mesenchymal cells found lining certain connective tissue spaces such as the anterior chamber of eye, perilymph spaces in the ear, and subdural and subarachnoid spaces. (05 Mar 2000) |
| ciliated epithelium | Any epithelium having motile cilia on the free surface. (05 Mar 2000) |
| pigmented retinal epithelium | Layer of unusual phagocytic epithelial cells lying below the photoreceptors of the vertebrate eye. The dorsal surface of the PRE cell is closely apposed to the ends of the rods and as discs are shed from the rod outer segment they are internalised and digested by the PRE. Do not have desmosomes or cytokeratins in some species. (18 Nov 1997) |
| pigment epithelium | Epithelium composed of cells containing granules of pigment or melanin, as in the retinal or iris pigment layer. (05 Mar 2000) |
| pigment epithelium of eye | Epithelium in the retina, ciliary body, and iris containing pigment granules. (12 Dec 1998) |
| pigment epithelium of optic retina | pigmented part of retina |
