The term 'Polarity' in simple columnar epithelium refers to:
Show answer and explanation
Correct answer: Apical-basal structural and functional asymmetry
Columnar cells are highly polarized. The apical domain faces the lumen and often has microvilli or cilia, while the basal domain is anchored to the basement membrane and contains different sets of transport proteins.
