¦ Apical surface (domain): Exposed to a luminal or external environment; site of primary function (absorption, Protection, etc.). ¦ Microvilli, composed of actin microfilaments anchored to terminal web.


1) T2-T4 with shallow, subbasal grooves, their basal margins faintly carinate, apical surface, 2) S1-S4 exposed, closely but rather obscurely punctate, apical 

For example, high-calcium state increased surface annexin A1, whereas high-oxalate condition increased surface α-enolase on apical membranes of renal tubular epithelial cells 12,13. The apical membrane has been argued to possess a ‘raft‐like’ character, while the basolateral surface has been compared with the plasma membrane of non‐polarized cells. Although both membrane domains contain cholesterol, it actually seems as if the basolateral surface has the higher content 34 , 35 . A single central lumen at the apical surface of epithelial cells is the feature of kidney tubules. Loss of Gal‐8 in MDCK cells, a well‐established kidney epithelial line that contributed to the understanding of many aspects of cellular polarity, disrupts the apical–basal polarity by mistargeting of Gp135.

This article will explain how to find the apical pulse location along with how to listen and palpate the apical pulse. Body has different types of epithelia. • Epithelia classification indicated by two- part name. ̶ Number of epithelial cell layers.

The secretions are enclosed in vesicles that move to the apical surface of the cell where the contents are released by exocytosis. For example, watery mucous containing the glycoprotein mucin, a lubricant that offers some pathogen protection is a merocrine secretion. The eccrine glands that produce and secrete sweat are another example. located on the apical surface of epithelial cells in the sensory organs of the inner ear at sites where they contact the overlying gels. Furthermore, we establish that otoancorin is defective in nonsyndromic deafness DFNB22. Materials and Methods Cloning of the Full-Length OtoacDNA. The 731-bp pB4D7 sequence 2016-01-11 · This final process of apical surface “emergence” (Figures 1A and S1A) is of particular interest and can be envisioned perhaps most simply as the converse of apical constriction, a well-defined cell behavior underlying both epithelial cell extrusion and epithelial folding (Guillot and Lecuit, 2013, Martin and Goldstein, 2014).
