The human nose is the first organ of the respiratory system. It is also the principal organ in the olfactory system. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two. The nose has an important function in breathing.
The septal nasal cartilage is also the main structure that provides the orientation of the nose, being the midline structure of the organ. With an offset septal nasal cartilage, the nose will appear crooked to the viewer. A crooked nose can block airflow coming from the nares to the lungs or vice versa. [4]
There is heavy variation in the structure of the nasal bones, accounting for the differences in sizes and shapes of the nose seen across different people. Angles, shapes, and configurations of both the bone and cartilage are heavily varied between individuals.
Some differences in human appearance are genetic, others are the result of age, lifestyle or disease, and many are the result of personal adornment. Some people have linked some differences with ethnicity, such as skeletal shape, prognathism or elongated stride. Different cultures place different degrees of emphasis on physical appearance and ...

Somel et al. said that 48% of the genes that affect the development of the prefrontal cortex change with age differently between humans and chimpanzees. Somel et al. said that there is a "significant excess of genes" related to the development of the prefrontal cortex that show "neotenic expression in humans" relative to chimpanzees and rhesus ...
On average, the aurofacial asymmetry is slightly larger for the eyes than for the nose, as shown by the figure. The gradual decrease of the aurofacial asymmetry with age until the beginning of adulthood. Source: figure 3 of Lussanet & Osse (2012), [8] data from Klingenberg et al. (2010). [12]
Rhinophyma is most common in males of European heritage over the age of 50. Males are 5 to 30 times as likely to be affected as females, possibly due to androgenic factors. [ 2 ] In the United States, people of predominantly Asian and African ancestry are only rarely affected by the condition.
