in what subtypes of epithelial tissue are goblet cells usually found
Goblet cell Goblet cells are typically found in the respiratory, reproductive and gastrointestinal tracts and are surrounded by stratified squamous cells.[1] Differentiation of epithelial cells into goblet cells plays a key role in the excessive mucus production seen in many diseases, such as asthma and cancer.
Epithelium By layer, epithelium is classed as either simple epithelium, only one cell thick (unilayered) or stratified epithelium as stratified squamous epithelium, stratified cuboidal epithelium, and stratified columnar epithelium that are two or more cells thick (multi-layered),[5][6] and both types of layering can be made up of any of the cell shapes.[3] However, when taller simple columnar epithelial cells are viewed in cross section showing several nuclei appearing at different heights, they can be confused with stratified epithelia. This kind of epithelium is therefore described as pseudostratified columnar epithelium.[7]
Vestibular fold They are lined with respiratory epithelium, while true vocal cords have stratified squamous epithelium.
Stomach In classical anatomy, the human stomach is divided into four sections, beginning at the gastric cardia,[6] each of which has different cells and functions.
