Columnar jointing is important primarily for its geological and aesthetic significance. It forms through the cooling and contraction of volcanic rock, creating distinctive hexagonal or polygonal columns that enhance our understanding of volcanic processes. These structures also influence landscape formation and drainage patterns. Additionally, columnar joints can have practical implications in construction and quarrying, as they often indicate the best places to extract rock.

Simple ciliated columnar epithelium has cilia that help move substances across the cell surface, whereas non-ciliated columnar epithelium lacks cilia. Non-ciliated columnar epithelium is involved in secretion and absorption, whereas ciliated columnar epithelium is mainly found in areas where the movement of mucus or particles is important, such as the respiratory tract.

When working with a plastic cold water storage cistern, jointing materials that contain solvents or adhesives that can deteriorate plastic should be avoided. This includes traditional solvent cement, which can cause cracking or weakening of the plastic. Instead, use jointing materials specifically designed for plastic, such as plastic-compatible sealants or gaskets. Always check the manufacturer's guidelines for suitable jointing options.

Epoxy resin can be used as a jointing compound.

The intestinal epithelium, which covers the small and large intestine, is simple columnar and nonciliated. It lines most of the organs of the digestive tract.

pseudostratified columnar epithelium
There are 8 types; simple squamous, simple columnar, simple cuboidal, stratified squamous, stratified cuboidal, stratified columnar, pseudostratified columnar, and transitional.
Pseudostratified columnar epithelium is a single layer of cells that appear to be layered due to varying cell heights, while stratified columnar epithelium has multiple layers of cells. Pseudostratified columnar epithelium is found in the respiratory tract and functions in secretion and absorption, while stratified columnar epithelium is found in the male urethra and functions in protection.
