− | Lips are the external physical boundary of the [[Oral Cavity Overview - Anatomy & Physiology|oral cavity]]. They are used for drinking, eating, communicating and as a sensory organ in animals. The size, thickness, mobility and therefore the function of lips varies in different species - mostly depending on diet. Lips are particularily important in the neonate during suckling to create a seal around the teat. | + | Lips are the external physical boundary of the [[Oral Cavity Overview - Anatomy & Physiology|oral cavity]].
