To sketch: A diagram of columnar epithelial cells with labeled apical and basolateral borders of the cells.
Introduction: Epithelial cells form the outer covering of all the parts of the body. Arrangement of these cells forms epithelial tissues. These tissues have been divided into various types of the basis of their structure and functions.
To determine: A brief explanation about various types of junctions present on the columnar epithelial cells.
Introduction: On the basis of structure, the epithelial tissues which have columnar cells are known as columnar epithelial tissues. The cells of these tissues are called columnar epithelial cells. Various cell junctions are present in these cells important for structural and functional support to the cell.
