human mouth (or oral cavity) is covered by an upper and lower .
The mouth starts
digestion by physically chewing the food and breaking it down with saliva.
The average male mouth holds a volume of about 100mL.
They play an important role in
speech (it is part of the vocal apparatus), facial expression, kissing, eating, drinking (especially with a straw), breathing, and smoking.
Infants are born with a sucking reflex, by which they instinctively know to suck for nourishment using their lips and jaw.
Cultural aspects Edit
According to general
etiquette, the mouth is kept closed, especially when chewing.
Lips are often adorned with
lipstick or lip gloss although in most human cultures this is an affectation for females only.
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.
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.
