WebIn humans, the parotid gland is composed of serous acini characterized by pyramidal cells surrounding the central acinar lumen. The submandibular gland acini contain a mixture of serous and mucous cells with flattened basal nuclei and pale eosinophilic cytoplasm (Figure 12). In the sublingual gland, mucinous acini predominate (Figure 14). WebSerous-rich acini contain granules high in ions, water, amylases, secretory immunoglobulins, and proline-rich proteins, but very low levels of mucin-type glycoproteins. 5 As such, both types of acini contribute differently to the overall functions of saliva. Mucous rich saliva acts more as a lubricant and protective barrier for the oral cavity.
