Abstract: In order to study the microstructure of different parts of the bovine pharynx, the histological structure of pharyngeal tissues of a 3.5-year-old bull was histologically observed. The bull pharynx tissue was collected and was used to prepare paraffin sections. The paraffin sections were subsequently stained using HE staining and PAS staining method to observe the tissue morphology and cell types of different parts of pharynx. Bovine nasopharynx mucosa layer belonged to pseudostratified columnar ciliated epithelium structure, among which, there were a large number of goblet cells but no cuticle; laryngopharynx and oropharynx belonged to stratified squamous epithelium structure, among which, cuticle was observed but goblet cells were absent.
