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.
The choroid plexus consists of a layer of cuboidal epithelial cells surrounding a core of capillaries and loose connective tissue. [3] The epithelium of the choroid plexus is continuous with the ependymal cell layer (ventricular layer) that lines the ventricular system. [5]
Stratified cuboidal epithelium, highlighting the nucleuses, the rest of the epithelial cells, and underlying connective tissue. Stratified cuboidal epithelium is a type of epithelial tissue composed of multiple layers of cube-shaped cells. Only the most superficial layer is made up of cuboidal cells, and the other layers can be cells of other ...
Transitional epithelium is made up of three types of cell layers: basal, intermediate, and superficial. [3] The basal layer fosters the epithelial stem cells in order to provide constant renewal of the epithelium. [4] These cells' cytoplasm is rich in tonofilaments and mitochondria; however, they contain few rough endoplasmic reticulum.
By layer, epithelium is classed as either simple epithelium, only one cell thick (unilayered), or stratified epithelium having two or more cells in thickness, or multi-layered – as stratified squamous epithelium, stratified cuboidal epithelium, and stratified columnar epithelium, [8]: 94, 97 and both types of layering can be made up of any of ...
Thyroid follicular cells (also called thyroid epithelial cells or thyrocytes [1]) are the major cell type in the thyroid gland, and are responsible for the production and secretion of the thyroid hormones thyroxine (T 4) and triiodothyronine (T 3). They form the single layer of cuboidal epithelium that makes up the outer structure of the almost ...
The cytotrophoblast contains cuboidal epithelial cells and is the source of dividing cells, and the syncytiotrophoblast is a syncytial layer without cell boundaries. The syncytiotrophoblast implants the blastocyst in the decidual epithelium by projections of chorionic villi , forming the embryonic part of the placenta.
The collecting duct system of the kidney consists of a series of tubules and ducts that physically connect nephrons to a minor calyx or directly to the renal pelvis.The collecting duct participates in electrolyte and fluid balance through reabsorption and excretion, processes regulated by the hormones aldosterone and vasopressin (antidiuretic hormone).
