Salivation is primarily controlled by nerves of the parasympathetic nervous system which release acetylcholine onto the acinar cells of the salivary glands. Salivation is primarily controlled by nerves of the parasympathetic nervous system which release acetylcholine onto the acinar cells of the salivary glands.

A. True

B. False

True

Explanation:

Salivation or the secretion of the saliva through the salivary glands present in the mouth are controlled by the nervous system.

The primary nervous system involved in the salivation is the parasympathetic system of neurons. The parasympathetic system is involved in the rest and digest response of the body.  

The parasympathetic system act by releasing acetylcholine in the acinar cells of the salivary glands. The acetylcholine binds to the receptors and causes a release of calcium. The calcium in the cell fuse with the membrane and thus saliva is released.

Thus, true is the correct answer.
