Question

what are the three different cells called?
if you are not sure then have a look at the tem screen again by lowering the labpad or click the view image button to see the image of the screen. note the position of the nuclei, and read the theory to learn more about the different cell types.
a) brush cells, goblet cells, and lymphocytes
b) absorptive enterocytes, goblet cells, and lymphocytes
c) absorptive enterocytes, brush cells, and goblet cells
d) absorptive enterocytes, brush cells, and lymphocytes

Explanation:

The three key cell types typical of the intestinal epithelium (the context implied by the TEM reference to cell nuclei and common lab exercises) are absorptive enterocytes (the primary nutrient-absorbing cells), goblet cells (mucus-secreting cells), and lymphocytes (immune cells found in the epithelial layer for mucosal defense). Brush cells are less commonly the focus of this standard trio in basic intestinal cell identification exercises.

Answer:

b) Absorptive enterocytes, goblet cells, and lymphocytes
