Drugs interfere with the way neurons send, receive, and process signals via neurotransmitters. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter in the body.
Answer: Acini
cells—water, electrolytes, mucus and enzymes
The Acini
cells are clusters of
cells, which is the basic
secretory units of salivary glands. These cells secretes fluid that contains water, electrolytes, mucus and enzymes, which flow out of the acinus into collecting
ducts. On the other hand, acinar cells secrete proteins such as the enzyme salivary amylase.
