poppy, in reference either to its tar-like appearance that may resemble some raw opium preparations or to Aristotles belief that it induces sleep in the fetus. Other uses
In biology, meconium describes the metabolic waste product from the pupal stage of an insect that is expelled through the anal opening of the adult upon eclosion from the pupa. Other insects, such as beetles and some Hymenoptera (Aculeata) expel the meconium at the end of the larval stage, before becoming a pupa. Gallery

A bronchocele is a segment of bronchus that is filled with mucus and completely enclosed so the mucus cannot drain out. This segment is usually dilated. It is also called bronchial mucocele. If there is no obstruction to the flow of mucus, it is called mucoid impaction of bronchus. A bronchocele results from obstruction of the bronchus. Overproduction of mucus can also contribute. Obstruction may occur due to scarring, a tumor, or congenital atresia.
