A histological specimen of submandibular salivary gland represents basket cells from which some processes radiate and embrace the secretory unit. Contraction of the processes of these cells helps in expelling secretions from the lumen of secretory units and moving them to the system of excretory ducts. Name these cells:

Adipocytes
|
|
|
Serous cells
|
|
|
Epithelial cells
|
|
|
Mucocytes
|
|
|
Myoepithelial cells

Explanation:
Detailed explanation-1: -Salivary glands consist of glandular secretory tissue (the parenchyma) and the supporting connective tissue (the stroma). The parenchyma consists of secretory acini, intercalated ducts, striated ducts in parotid and submandibular glands, and collecting ducts, which join to form the main duct at the hilum.
Detailed explanation-2: -Functions. The secretory cells of the submandibular gland have distinct functions. In particular, the serous cells produce salivary amylase, which aids in the breakdown of starches in the mouth. Mucous cells secrete mucin which aids in the lubrication of the food bolus as it travels through the esophagus.
