What shape of cell is described as taller than they are wide?

The shape of a cell described as taller than it is wide is referred to as columnar. This terminology is commonly used to categorize epithelial cells based on their height and shape. Columnar cells are typically elongated and can be found in tissues where absorption and secretion occur, such as the lining of the digestive tract. Their structure allows for a greater surface area for these functions compared to other cell shapes.

In contrast, cuboidal cells are roughly equal in height and width, spherical cells are round, and squamous cells are flat and thin. Each of these shapes serves different functions in the body, but the key aspect of columnar cells is their distinct height that exceeds their width, making them easily recognizable in histological studies.
