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.
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.
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 .
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 ...
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 ...
The eccrine gland opens out through the sweat pore. The coiled portion is formed by two concentric layers of columnar or cuboidal epithelial cells. [8] The epithelial cells are interposed by the myoepithelial cells. Myoepithelial cells support the secretory epithelial cells. The duct of eccrine gland is formed by two layers of cuboidal ...
Club cells, also known as bronchiolar exocrine cells, [1] are low columnar/cuboidal cells with short microvilli, found in the small airways (bronchioles) of the lungs. [2] They were formerly known as Clara cells. Club cells are found in the ciliated simple epithelium. These cells may secrete glycosaminoglycans to protect
Components that are essential for osteoblast bone formation include mesenchymal stem cells (osteoblast precursor) and blood vessels that supply oxygen and nutrients for bone formation. Bone is a highly vascular tissue, and active formation of blood vessel cells, also from mesenchymal stem cells, is essential to support the metabolic activity of ...
