| MeSH | Oral+cavity |
The mouth is the first portion of the alimentary canal that receives food and saliva.[1] The oral mucosa is the mucous membrane epithelium lining the inside of the mouth.
In addition to its primary role as the beginning of the digestive system, in humans the mouth also plays a significant role in communication. While primary aspects of the voice are produced in the throat, the tongue, lips, and jaw are also needed to produce the range of sounds included in human language.
The mouth, normally moist, is lined with a mucous membrane, and contains the teeth. The lips mark the transition from mucous membrane to skin, which covers most of the body.

In humans [link]
Mouth cavity [link]
The first space of the mouth is the mouth cavity, bounded laterally and in front by the alveolar arches (containing the teeth), and posteriorily by the isthmus of the fauces. The oral cavity is also known as the mouth which swallows food that then goes down the esophagus and into the stomach.
Function [link]
The mouth plays an important role in eating, drinking and breathing. Infants are born with a sucking reflex, by which they instinctively know to suck for nourishment using their lips and jaw.
Cultural aspects [link]
Lips can be adorned with lipstick or lip gloss, although in most cultures this is typically only practiced by females. Both men and women, however, apply lip balm in order to soothe chapped or dry lips.
Piercings in or around the mouth have been made popular by younger generations, including those on the lip or tongue. The uvula piercing, while increasing in popularity, remains relatively rare.
Development [link]
The philtrum is the vertical groove in the upper lip, formed where the nasomedial and maxillary processes meet during embryo development. When these processes fail to fuse fully, a hare lip and/or cleft palate can result. This can result in the encouraging process of the release of metabolic wastes.
The nasolabial folds are the deep creases of tissue that extend from the nose to the sides of the mouth. One of the first signs of age on the human face is the increase in prominence of the nasolabial folds.
In non-human animals [link]
Some animal phyla, including vertebrates, have a complete digestive system, with a mouth at one end and an anus at the other. Which end forms first in ontogeny is a criterion used to classify animals into protostome and deuterostome. The first space of the mouth is the mouth cavity, bounded laterally and in front by the alveolar arches (containing the teeth), and posteriorly by the isthmus of the fauces.[1]

The song, a playful and suggestive tune, was often referred to having something related to sexual themes. Bainbridge stated that "(Any sexuality on "Mouth" was) not deliberate - it was definitely not a sexual song. It's just honest - about a relationship, how you feel in a relationship. Sometimes you feel you're in control and the next thing, you're insecure - it's the role playing thing. To me, it's not about straight up sexuality. It doesn't bother me if people connect with that, because obviously it's there, but it wasn't something I was aware of".
