In the penile urethra, the glands of Littre may be located in the corners from which In these cases, it is difficult to trace the continuity of different cells from base to apex and the epithelium may appear stratified even though it contains just one layer of cells. Sep 11, 2021 · Pseudostratified Columnar Epithelium Location and Examples The male reproductive system’s epididymis and vas deferens are lined by non-ciliated pseudostratified columnar epithelium. The layered appearance of the nuclei make this epithelium appear stratified, hence the term, pseudostratified. Find out where this tissue is located in the respiratory and reproductive tracts and how it differs from other epithelia. Walls of smallest ducts of glands and kidney tubules Pseudostratified columnar epithelium is a type of epithelium that appears to be stratified but instead consists of a single layer of irregularly shaped and differently sized columnar cells. The shorter cells have nuclei nearest the basement membrane. (4) Pseudostratified columnar epithelium “Pseudo” means “false”. Locations: Male urethra, large ducts of glands. location: trachea (ciliated), glands (non-ciliate) function: secretion and movement by Oct 9, 2014 · Pseudostratified columnar epithelium is named because its nuclei are “stratified”, but the cells are not.
