| supra-anal | Above the anus. Synonym: superanal. (05 Mar 2000) |
|---|---|
| deep part of external anal sphincter | deep part of external anal sphincter |
| internal anal sphincter | <anatomy> A smooth muscle ring, formed by an increase of the circular fibres of the rectum, situated at the upper end of the anal canal, internal to the outer voluntary external anal sphincter. This sphincter is maximally-contracted when the rectal ampulla is at rest -empty or relaxed to accommodate a distending faecal mass. It is inhibited with filling of the ampulla, increased distension and peristalsis. Synonym: musculus sphincter ani internus, internal sphincter muscle of anus. (05 Mar 2000) |
| external anal sphincter | A fusiform ring of striated muscular fibres surrounding the anus, attached posteriorly to the coccyx and anteriorly to the central tendon of the perineum; it is subdivided, often indistinctly, into a subcutaneous part, a superficial part and a deep part for descriptive purposes. Synonym: musculus sphincter ani externus, external sphincter muscle of anus. (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) |
