Which of the following is NOT a primary location for stratified squamous non-keratinized epithelium?

Explanation:
Stratified squamous non-keratinized epithelium protects surfaces that stay moist and endure abrasion without forming keratin. It is found on the cornea, the conjunctiva, and the esophagus, all of which require flexible, moist protection. The gastrointestinal tract, in contrast, is lined mostly by simple columnar epithelium specialized for absorption and secretion. The esophagus is the notable exception within the GI tract, using stratified squamous non-keratinized epithelium to withstand constant friction from swallowed material. Therefore, the GI tract as a general region is not a primary location for this epithelium.
