Nose cone shapes and equations General dimensions. In all of the following nose cone shape equations, L is the overall length of the nose cone and R is the radius of the base of the nose cone. y is the radius at any point x, as x varies from 0, at the tip of the nose cone, to L. The equations define the two-dimensional profile of the nose shape.
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.
Nasal cavity. The nasal cavity is a large, air-filled space above and behind the nose in the middle of the face. The nasal septum divides the cavity into two cavities, [1] also known as fossae. [2] Each cavity is the continuation of one of the two nostrils. The nasal cavity is the uppermost part of the respiratory system and provides the nasal ...
The distinctive human nose shape, nostrils, and nasal septum. The cheeks, covering the maxilla and mandible (or jaw), the extremity of which is the chin. The mouth, with the upper lip divided by the philtrum, sometimes revealing the teeth. Facial appearance is vital for human recognition and communication.

[2] In humans, these two parts are the neurocranium (braincase) and the viscerocranium ...
A figure drawing is a drawing of the human form in any of its various shapes and postures, using any of the drawing media. The term can also refer to the act of producing such a drawing. The degree of representation may range from highly detailed, anatomically correct renderings to loose and expressive sketches.
OMIM (Online Mendelian Inheritance in Man) [3] is a comprehensive database of human genotype–phenotype links. Many visible human traits that exhibit high heritability were included in the older McKusick's Mendelian Inheritance in Man. Before the discovery of genotyping, they were used as genetic markers in medicolegal practice, including in ...
A syrphid fly using its proboscis to reach the nectar of a flower. A proboscis ( / proʊˈbɒsɪs, - kɪs /) is an elongated appendage from the head of an animal, either a vertebrate or an invertebrate. In invertebrates, the term usually refers to tubular mouthparts used for feeding and sucking. In vertebrates, a proboscis is an elongated nose ...
