Question

move through the image and have a close look at the edge of the epithelium. try to identify the basal side facing towards the lamina propria and the apical side bordering the lumen. you can also click the view image button to learn more. which of the statements below is correct? a) the apical side of the epithelium is facing towards the left b) the basal side is facing towards the left side of the screen c) the apical side is on top of the screen and the basal side on the bottom d) the basal side faces towards the lumen

Explanation:

Epithelial tissue has an apical side that borders the lumen (the hollow internal space of an organ/structure) and a basal side that attaches to the underlying lamina propria (connective tissue). In typical histological views of such epithelium, the basal side is oriented toward the underlying tissue (often the left or bottom of standard slides, but based on core definitions:

• Option a: Incorrect, apical side faces the lumen, not left.
• Option b: Correct, basal side faces the lamina propria, which would be the left side here.
• Option c: Incorrect, this orientation does not match the standard apical-basal alignment with lumen and lamina propria.
• Option d: Incorrect, the apical side faces the lumen, not the basal side.

Answer:

b) The basal side is facing towards the left side of the screen
