Tubular parts of nephrons - Cuboidal epithelium
Cuboidal epithelium is present in th tubular parts of nephron (PCT and DCT). It consists of short, cube -shaped cells with round nuclei located in the centre of the cell. These cells forms microvilli to increase the absorptive surface area of the cell.
Other correctly matched points are
Inner lining of salvasry ducts is lined by compound epithelium. Moist surface of bucaal cavity is lined by compound epithelium. Inner surface of bronchioles is lined by ciliated epithelium.
