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.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
