It is located in the conjunctiva inside the eyelids and areas of tissue transition.
Enter the important histological characteristics of columnar epithelium into the table. You know the nuclei of the columnar epithelium lie in a row toward the basal part of the cell. It is because different cellular heights and nuclei are also placed at a different levels. Columnar epithelium with goblet cells tissue / organ:
Notice how the simple columnar cells lining the uterine cervix transitions to stratified squamous epithelium.
Stratified tissues are named based on the shape of the most apical cells. The pseudostratified columnar epithelium comprises a single layer of cells but seems to be multilayered.

Epithelial tissue is classified in two ways:

So an epithelium that has several layers and the apical cells are flattened and scale shaped, the name of the specific tissue is stratified squamous epithelium.
But, in the pseudostratified columnar epithelium, the nuclei appear to be arranged into two or more layers. The drawings of histology images were originally. In the usual columnar epithelium the nuclei lie in a row, towards the bases of the cells; Learn vocabulary, terms, and more with flashcards, games, and other study tools.
