Veiled cells refer to a specific type of cells found in the salivary glands. These cells, also known as brush cells or bush cells, are characterized by the presence of numerous long, finger-like projections or microvilli on their surface. The term "veiled" is derived from the appearance of these microvilli, which give the cells a veiled or brush-like appearance when viewed under a microscope.
This specialized cell type is primarily found in the ductal system of the salivary glands, particularly in the intercalated and striated ducts. Veiled cells play a crucial role in the production and modification of saliva. They are responsible for secreting various substances, including electrolytes, enzymes, and proteins, into the saliva to facilitate digestion and maintain oral health.
The microvilli present on the surface of veiled cells greatly increase their surface area, allowing for more efficient absorption and secretion of substances. This structural adaptation enables the cells to effectively regulate the composition and flow of saliva within the ductal system.
Furthermore, veiled cells are involved in sensing and responding to various stimuli in the salivary gland environment. They possess sensory receptors that allow them to detect changes in the pH, osmolarity, and composition of the saliva. Upon sensing these changes, veiled cells can initiate appropriate responses to maintain the homeostasis of saliva production and composition.
In conclusion, veiled cells are a specific type of ductal cells in the salivary glands characterized by numerous microvilli on their surface. They are involved in the secretion, modification, and regulation of saliva, contributing to oral health and digestive processes.
