Adult human noses have hairs, which serve as a crude air filter to stop foreign particles from entering the nasal cavity, as well as to help collect moisture. [1] Nasal hair is different from the cilia of the ciliated lining of the nasal cavity. These cilia are microtubule -based structures ...

The three stages of hair growth are the anagen, catagen, and telogen phases. Each strand of hair on the human body is at its own stage of development. Once the cycle is complete, it restarts and a new strand of hair begins to form. The growth rate of hair varies from individual to individual depending on their age, genetic predisposition and a ...

The head rests on the neck, and the seven cervical vertebrae support it. The human head typically weighs between 2.3 and 5 kilograms (5.1 and 11.0 lb) Over 98% of humans fit into this ...
Rhinophyma is a condition causing development of a large, bulbous nose associated with granulomatous infiltration, commonly due to untreated rosacea. [1] The condition is most common in older white males.
54378. Anatomical terminology. [ edit on Wikidata] 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 ...
