terminal bar

[′tər·mən·əl ‚bär] (cell and molecular biology) One of the structures formed in certain epithelial cells by the combination of local modifications of contiguous surfaces and intervening intercellular substances; they become visible with the light microscope after suitable staining and appear to close the spaces between the epithelial cells of the intestine at their free surfaces.

terminal bar

ter·mi·nal bar

dark spots or bar's (depending on the plane of section) in the lateral boundary between the apical ends of columnar epithelial cells; this region corresponds with the area of the junctional complex and the thin filaments that anchor on the zonula adherens.

terminal bar

Cytology
The portion of the cell below and perpendicular to the cilia seen in pap-stained smears of ciliated columnar cells, which corresponds to the belt desmosomes, actin filaments and other proteins aggregated at the apical end of the cells.
Normal finding
Terminal bars occur in the normal respiratory epithelium, and in tubal metaplasia of the uterine cervix.
Abnormal finding
Terminal bar-like structures have been described in adenomas, adenocarcinoma, transitional and papillary carcinoma of the urinary bladder, synovial sarcomas and mesotheliomas.

ter·mi·nal bar

(tĕr'mi-năl bahr) Dark spots or bars (depending on the plane of section) in the lateral boundary between the apical ends of columnar epithelial cells.
