Questions: Identify the epithelium (VELLOW line). A. Pseudostratified B. Simple columnar C. Stratified cuboidal D. Stratified squamous

Solution Steps

The yellow line indicates a single layer of cells resting on the basement membrane. The cells are roughly equal in height and width, resembling cubes or squares.

• Pseudostratified: Appears to be multiple layers due to nuclei at different heights, but all cells contact the basement membrane.
• Simple columnar: Single layer of tall, column-shaped cells.
• Stratified cuboidal: Multiple layers of cube-shaped cells.
• Stratified squamous: Multiple layers of flattened cells.

The image doesn't show multiple layers, so stratified cuboidal and stratified squamous are incorrect. The cells aren't tall and columnar, so simple columnar is incorrect. While the nuclei are not perfectly aligned, all cells appear to contact the basement membrane.
