Human Anatomy
In humans, the premaxilla (or os incisivum) is the part of the maxilla which bears the incisor teeth, and encompasses the anterior nasal spine and alar region. In the nasal cavity, the premaxillary element projects higher than the maxillary element behind. The palatal portion of the premaxilla is a bony plate with a generally transverse orientation. The incisive foramen is bound anteriorly and laterally by the premaxilla and posteriorly by the palatine process of the maxilla.

Famous quotes containing the words human and/or anatomy:
“It is not possible, for a poet, writing in any language, to protect himself from the tragic elements in human life.... [ellipsis in source] Illness, old age, and death—subjects as ancient as humanity—these are the subjects that the poet must speak of very nearly from the first moment that he begins to speak.”
—Louise Bogan (1897–1970)
“Man is a shrewd inventor, and is ever taking the hint of a new machine from his own structure, adapting some secret of his own anatomy in iron, wood, and leather, to some required function in the work of the world.”
—Ralph Waldo Emerson (1803–1882)
