mucous
Adjective
pl: nullpast: nullpp: nulling: nullcomp: nullsup: null
This term is strictly technical and biological, used to describe the tissues or glands that produce a slippery, protective secretion. It carries a clinical tone and is almost exclusively found in medical textbooks or health reports rather than casual conversation. It is frequently confused with mucus, which is the actual substance produced. While mucus is the sticky fluid itself, mucous describes the anatomy that creates or contains that fluid, such as the lining of the respiratory tract.
