{{Main|Tongue}}
The '''tongue''' is skeletal muscle on the floor of the [[mouth]] of most vertebrates, that manipulates [[food]] for chewing ([[mastication]]) and [[swallowing]] (deglutition). It is sensitive and kept moist by [[saliva]]. The underside of the tongue is covered with a smooth [[mucous membrane]]. The tongue also has a touch sense for locating and positioning food particles that require further chewing. The tongue is used to roll food particles into a [[Bolus (digestion)|bolus]] before being transported down the [[esophagus]] through [[peristalsis]].

The [[sublingual]] region underneath the front of the tongue is a location where the [[oral mucosa]] is very thin, and underlain by a plexus of veins. This is an ideal location for introducing certain medications to the body. The sublingual route takes advantage of the highly [[Blood vessel|vascular]] quality of the oral cavity, and allows for the speedy application of medication into the cardiovascular system, bypassing the gastrointestinal tract.
