Multiple Choice

Which of the following are visible characteristics of ciliated pseudostratified columnar epithelium?

Cells appear to be layered due to varying nuclei positions, all cells touch the basement membrane, and cilia are present on the apical surface.

Cells are cube-shaped and arranged in multiple layers with microvilli.

Cells are spindle-shaped and found in bundles with no surface specializations.

Cells are flat and arranged in a single layer without cilia.

Verified step by step guidance

Step 1: Understand the structure of ciliated pseudostratified columnar epithelium. This type of epithelium appears layered because the nuclei of the cells are at different heights, but all cells are in contact with the basement membrane. Additionally, cilia are present on the apical surface, which helps in moving substances like mucus.

Step 2: Compare the characteristics of ciliated pseudostratified columnar epithelium with the other options provided. For example, cube-shaped cells arranged in multiple layers with microvilli describe stratified cuboidal epithelium, not pseudostratified columnar epithelium.

Step 3: Evaluate the option describing spindle-shaped cells found in bundles with no surface specializations. This description matches smooth muscle tissue, not epithelial tissue.

Step 4: Analyze the option describing flat cells arranged in a single layer without cilia. This matches simple squamous epithelium, which is specialized for diffusion and filtration, not pseudostratified columnar epithelium.

Step 5: Confirm that the correct answer aligns with the visible characteristics of ciliated pseudostratified columnar epithelium: cells appear layered due to varying nuclei positions, all cells touch the basement membrane, and cilia are present on the apical surface.
