This functional tissue unit (FTU) illustration includes cell types related to the parotid gland ducto-acinar FTU in the ASCT+B Table [Mouth v1.0](link to table TBD). Multiple histology atlases, especially Netter’s Essential Histology with Correlated Histopathology (Ovalle and Nahirney 2021), Junqueira’s Basic Histology Text & Atlas (Mescher 2021), Human Microscopic Anatomy (Krstić 1994), Histology: A Text and Atlas (Ross et al. 2003), and Netter’s Head and Neck Anatomy for Dentistry (Norton and Willett 2025) were referenced. Uberon describes this FTU as follows: "The parotid gland is the largest of the salivary glands. It is found wrapped around the mandibular ramus, and it secretes saliva through Stensen's duct into the oral cavity, to facilitate mastication and swallowing."
