They are lined with a stratified columnar or stratified squamous epithelium.
High density of mitochondria within basal in-foldings of the cell membrane.
They are always extralobular and surrounded by a thick layer of connective tissue, just proximal to where the ducts open into the oral cavity.

You are seeing a 2 week old infant for a well child check while on your pediatrics rotation. During your interview with Mom she
mentions that the baby seems to have difficulty latching to breastfeed and ³just can¶t seem to create any suction´You and your

A 5-year-old boy presents to your ENT clinic with an opening in the upper part of his neck that has had intermittent mucoid
discharge. The opening of the tract moves with swallowing and protrusion of the tongue. No dysphagia, halitosis (bad breath) or
