In a saliva of the patient the contents of enzymes is reduced. What cells of
secretory portion do not work?
Serocytes
O Myoepitheliocytes
Mucocytes
Striated
O Mucous

Expert Solution

Explanation

Salivary glands are made up of secretory units also known as acini and ducts. Ducts are highly composed of striated cells. Secretion takes place in serous and mucous. Cellular composition of secretory units are serocytes, mucocytes and Myoepitheliocytes, serocytes + mucocytes and mucocytes+ serocytes. Acini cells secretes enzymes, electrolytes, water that move from acini to collecting ducts. Mucus is thick whereas Serous secretion is more liquid than mucus and consist of water and proteins mainly the digestive enzyme amylase. Saliva contain enzymes like amylase which is very important and responsible for breaking starch into simpler substances.
