Cell shapes: columnar cells
Columnar cells are shaped like columns and, as such, are much taller than they are wide. Here, a single row of columnar cells lines the digestive tract. The nucleus conforms to the cell’s shape, with the long axis of its oval parallel to the height of the cell. The lateral cell boundaries are also visible in this section. Small intestine 1000x
