Nose picking is a common habit, slightly taboo. Medical risks include the spread of infections, nosebleeds and rarely perforation of the nasal septum. When it becomes compulsive, it is called rhinotillexomania. Wiping your nose with your hand, commonly known as an “allergic greeting,” is also a slight taboo and can also lead to the spread of infections. The usual as well as rapid or rough wipe of the nose can also cause a wrinkle (known as a transverse nasal fold or groove) to pass over the nose and can lead to permanent physical deformities that can be observed in childhood and adulthood. [97] [98] In children, the nose is a common place of foreign bodies. [67] The nose is one of the areas exposed to frostbite. [68] During the sixth week, the nasal cavity deepens as it enters the underlying mesenchyma. [47] At this time, the median nasal processes migrate to each other and merge, fuse and form the primardium of the bridge of the nose and septum. [48] Migration is medial supported by increased growth of maxillary protrusions, which compress median nasal processes to the midline.
Their fusion takes place on the surface and also at a deeper level. [47] Fusion forms the intermaxillary segment, which is continuous with the rostral part of the nasal septum. The tips of the maxillary processes also develop and merge with the intermaxillary process. The intermaxillary process leads to the philtrum of the upper lip. [47] Normal development is crucial because the newborn breathes through the nose for the first six weeks and any nasal blockage requires emergency treatment to remove it. [51] The nose is the most important part of the human face. It has both internal and external parts. If you are in show business, the appearance of the outer part is certainly very important. In addition to aesthetics, however, the outer nose also protects the inner nose and allows air to enter. The inner part of the nose is called the nasal cavity.
It is involved in breathing, sense of smell, speech and taste. On this page we will examine the anatomy of the nose, emphasizing the anatomical importance of the structure of the nasal cavity. The skin of the nose varies in thickness along its entire length. [3] From the glabella to the bridge (the nasofrontal angle), the skin is thick, quite supple and mobile. It narrows to the bridge, where it is thinnest and least flexible, as it is closest to the underlying bone. From the bridge to the tip of the nose, the skin is thin. The tip is covered with skin as thick as the upper part and has many large sebaceous glands. [3] [13] The thickness of the skin varies, but is always separated from the underlying bones and cartilage by four layers – a superficial layer of fat; a fibromuscular layer continued from SMAS; a deep layer of fat and periosteum. [3] Most of the outer nose – the back and top – is fed by the infratrochlear nerve (a branch of the nasociliary nerve). [3] [13] The outer branch of the anterior ethmoid nerve also supplies the skin areas between the root and the alae. [13] The outer nose consists of the surface and skeletal structures that lead to the external appearance of the nose and contribute to its many functions (figure). The root is the area of the nose between the eyebrows.
The bridge is the part of the nose that connects the root to the rest of the nose. The dorsum nasi is the length of the nose. The tip is the tip of the nose. On both sides of the tip, the nostrils are formed by the alae (singular = ala). An ala is a cartilaginous structure that forms the lateral side of each nostril (plural = nostrils) or nasal opening. The philtrum is the concave surface that connects the tip of the nose to the upper lip. Blood supply to the nose occurs through the branches of the eye, maxillary and facial arteries – branches of the carotid arteries. The branches of these arteries anastomosate at the plexuses in and under the nasal mucosa.
[3] In the septal region, the Kiesselbach plexus is a common site of nosebleeds. A broken nose can result from trauma. Minor fractures can heal on their own. Surgery known as reduction can be performed on more serious fractures that result in dislocations. [84] Repetition is the key to a successful study of anatomy.

It is a pyramid-shaped structure, the root of which is upper and the tip is lower. The root is continuous with the anterior surface of the head and the part between the root and the top is called the back of the nose. Inferior to the tip are the two naras (nostrils), which are the openings of the nasal cavity. The scars are separated by the nasal septum and are bordered laterally by the ala nasi (wings of the nostrils). Your nose is also an important aspect of the appearance and well-being of your face.
Finally, several conditions that one is likely to encounter in relation to the nasal cavity are nosebleeds, nasal infections, and sometimes even a deviant septum. The nasal muscle is fed by the branches of the cheek. It can also be provided from one of the zygomatic branches. The procerus is fed by the temporal branches of the facial nerve and the lower branches of the cheekbone; A supply of the oral branch has also been described. Septa depressants are innervated by the oral branch and sometimes by the cheekbone branch of the facial nerve. The levator labii superioris alaeque nasi is innervated by the zygomatic and upper oral branches of the facial nerve. [3] Some people opt for cosmetic surgery (called rhinoplasty) to change the appearance of their nose. Nasal piercings, such as in the nostril, septum or bridge, are also common. In some Asian countries such as China, Japan, South Korea, Malaysia, Thailand and Bangladesh, rhinoplasty is often performed to create a more developed nasal bridge or “high nose”. [88] Similarly, “DIY nose lifts” in the form of reusable cosmetics have become popular and are sold in many Asian countries such as China, Japan, South Korea, Taiwan, Sri Lanka and Thailand. [89] [90] [91] A high-voltage nose is a common beauty ideal in many Asian cultures, dating back to the beauty ideals of ancient China and India. [92] [93] Werner syndrome, a disease associated with premature aging, causes a “bird-like” appearance due to a pinching of the nose.
[39] The nose has an important function when breathing.
