Nose (Nasus externus) anatomy - Anatomy of the nose
There may be recognized in the nose a base, which is directed downward, and a root, situated between the two orbits; the rounded anterior surface is directed forward and upward and is termed the dorsum, and it terminates in the tip of the nose, or apex nasi. The margins representing the lower borders of the base pass backward from the tip to form the alee, and they constitute the lateral boundaries of the nostrils (nares), which are separated from each other by the antero-inferior portion of the nasal septum, the membranous septum.

Change is a fundamental characteristic of all living things. The human body during its life cycle accordingly passes through various phases of form and structure. In the earliest embryonic phases of development, the changes are very rapid, decreasing in rapidity during the later fetal stages, but continuing at a diminishing rate throughout infancy, childhood and youth up to the adult. Following the acme of maturity, changes continue which lead gradually to senescence and final death of the body.
