Buccinator
the trumpeter's muscle, one of the maxillary group of muscles of the cheek. They are the active agents in mastication, and are beautifully adapted for it. The buccinator circumscribes the cavity of the mouth and, aided by the tongue, keeps the food under the pressure of the teeth; it also helps to shorten the pharynx from before backward, and thus assists in deglutition.
BUCCINIDÆ, a family of mollusks belonging to the order prosobranchiata, and the section siphonostomata. They constitute part of Cuvier's buccinoida.
They have the shell notched in front, or with the canal abruptly reflected so as to produce a varix on the front of the shell.
The leading genera are buccinum terehra, eburna, nassa, purpura, cassis, dolium, harpa and oliva.
