Simple cuboidal epithelium is a type of epithelium that consists of a single layer of cuboidal (cube-like) cells which have large, spherical and central nuclei.. Simple cuboidal epithelium is found on the surface of ovaries, the lining of nephrons, the walls of the renal tubules, parts of the eye and thyroid, and in salivary glands.
Simple columnar epithelium and simple cuboidal epithelium in the collecting ducts of the pig kidney. The walls of the large and small connecting tubules (a and b respectively), the circular structures, are formed by simple columnar epithelium (a) and simple cuboidal epithelium (b). The segments of the system are as follows:
Thyroid follicular cells form a simple cuboidal epithelium and are arranged in spherical thyroid follicles surrounding a fluid filled space known as the colloid. The interior space formed by the follicular cells is known as the follicular lumen.
Simple cuboidal epithelium commonly differentiates to form the secretory and duct portions of glands. [6] Stratified cuboidal epithelium protects areas such as the ducts of sweat glands, [7] mammary glands, and salivary glands. Columnar Columnar epithelial cells are elongated and column-shaped and have a height of at least four times their width.
intestinal epithelium: digestive: rectum: Simple columnar, non-ciliated - digestive: anus: Stratified squamous, non-keratinized superior to Hilton's white line Stratified squamous, keratinized inferior to Hilton's white line - digestive: gallbladder: Simple columnar, non-ciliated - endocrine: thyroid follicles: Simple cuboidal - nervous ...
The intestinal epithelium is the single cell layer that forms the luminal surface (lining) of both the small and large intestine (colon) of the gastrointestinal tract. Composed of simple columnar epithelium its main functions are absorption, and secretion. Useful substances are absorbed into the body, and the entry of harmful substances is ...
Fig.6) Cross-sectional histologic preparation showing (b)small connecting tubules with simple columnar epithelium and (a) large connecting tubules with simple cuboidal epithelium. Each distal convoluted tubule delivers its filtrate to a system of collecting ducts, the first segment of which is the connecting tubule. The collecting duct system ...
There are many kinds of epithelium, and nomenclature is somewhat variable. Most classification schemes combine a description of the cell-shape in the upper layer of the epithelium with a word denoting the number of layers: either simple (one layer of cells) or stratified (multiple layers of cells).
