Microvilli on the apical surface increase its surface area. This facilitates transport of numerous small molecules into the enterocyte from the intestinal lumen . These include broken down proteins , fats , and sugars , as well as water, electrolytes , vitamins , and bile salts .
Epithelial polarity is one example of the cell polarity that is a fundamental feature of many types of cells. Epithelial cells feature distinct 'apical', 'lateral' and 'basal' plasma membrane domains. Epithelial cells connect to one another via their lateral membranes to form epithelial sheets that line cavities and surfaces throughout the ...
The upper front surface of the tongue just behind the tip, called the blade of the tongue ; The surface of the tongue under the tip ; The body of the tongue which is sometimes further divided into front and back; The base a.k.a. root of the tongue and the throat ; The aryepiglottic fold inside the throat (aryepiglottal)
This specialization makes the epithelium somewhat water-resistant, so is found in the mammalian skin. The lining of the oesophagus is an example of a non-keratinized or "moist" stratified epithelium. [11] Parakeratinized In this case, the most apical layers of cells are filled with keratin, but they still retain their nuclei.

A laminal consonant is a phone (speech sound) produced by obstructing the air passage with the blade of the tongue, the flat top front surface just behind the tip of the tongue, in contact with upper lip, teeth, alveolar ridge, to possibly, as far back as the prepalatal arch, although in the last contact may involve parts behind the blade as ...
The brush border on the apical surface of the epithelial cells is covered with glycocalyx, which is composed of oligosaccharides attached to membrane glycoproteins and glycolipids. [7] TEM image of a thin section cut through an epithelial cell showing the luminal surface (apical end) of the cell packed with microvilli that make up the absorbing ...
For example, structures may be described relative to the anterior superior iliac spine, the medial malleolus or the medial epicondyle. Anatomical lines are theoretical lines, used to describe anatomical location. For example, the mid-clavicular line is used as part of the cardiac exam in medicine to feel the apex beat of the heart.
