In most humans, it also houses the nosehairs, which catch airborne particles and prevent them from reaching the lungs. Within and behind the nose is the olfactory mucosa and the sinuses. Behind the nasal cavity, air next passes through the pharynx, shared with the digestive system, and then into the rest of the respiratory system. In humans, the nose is located centrally on the face;on most other mammals, it is on the upper tip of the snout. Nasal hair or Nose hair consists of small hairs that are in the nose. ...

As an interface between the body and the external world, the nose and associated structures frequently perform additional functions concerned with conditioning entering air (for instance, by warming and/or humidifying it, also for flicking if moving and by mostly reclaiming moisture from the air before it is exhaled (as occurs most efficiently in camels). For other uses, see Camel (disambiguation). ...


In most mammals, the nose is the primary organ for smelling. As the animal sniffs, the air flows through the nose and over structures called turbinates in the nasal cavity. The turbulence caused by this disruption slows the air and directs it toward the olfactory epithelium. At the surface of the olfactory epithelium, odor molecules carried by the air contact olfactory receptor neurons which transduce the features of the molecule into non painful electrical impulses in the brain. Olfaction (also known as olfactics) refers to the sense of smell. ...

In cetaceans, the nose has been reduced to the nostrils, which have migrated to the top of the head, producing a more streamlined body shape and the ability to breathe while mostly submerged. Conversely, the elephant's nose has become elaborated into a long, muscular, manipulative organ called the trunk.

Symptoms Bent or crooked nose Swelling Bruising around the nose or eyes Nose bleed Blocked nasal passages Grating sound or feeling when nose is touched or rubbed


Diagnostics Broken noses are diagnosed through physical examination. X- rays are usually not needed, overly bent or crooked noses followed by nose bleed and intense pain usually indicates a broken nose. A broken nose is rarely life threatening Cant be transmitted, can only be acquired by facial trauma to the nose



Treatment Apply ice and keep the head elevated. Pain killers to manage pain relief For more complicated fractures, a doctor usually moves the bone or cartilage back into place if its crooked Splints or nasal packing (packing the nose with gauze) may also be necessary


Pathophysiology All nose bleeds are do to tears in the mucosal lining and the many blood vessels it contains. Fragility or injury may cause the tears, while inflammations or coagulation problems or other disorders may make the injury harder to repair


Prevention Wear the appropriate head gear for the type of physical activities



Orbital


Definition: a break in one of the bones that make up the orbit. Made up of 6 bones; Frontal, ethmoidal, lacrimal, sphenoid bones, maxilla and zygoma


Causes Trauma to the orbital area


Pathophysiology Pressure in the orbit causes fractures within the bones of the eye socket. Blow-out fracture- per orbital fat and extra ocular muscles can be entrapped in the fracture Can not be transmitted, only physically acquired Not life-threatening


Symptoms Swelling and redness Difficulty in ocular movement Double vision


Diagnostics May require CT scanning to evaluate the floor and medial wall of the orbit. If patient decrease of visual acuity, CT scans can help determine how the fracture is involved with the optic nerve


Treatment Simple fracture with out entrapment does not require surgery. Scanning and surgery may be necessary if entrapment occurs


Prevention Wear necessary protective equipment when involved with certain physical activities

Nose - Wikipedia, the free encyclopedia (615 words)
Anatomically, a nose is a protuberance in vertebrates that houses the nostrils, or nares, which admit and expel air for respiration.
As an interface between the body and the external world, the nose and associated structures frequently perform additional functions concerned with conditioning entering air (for instance, by warming and/or humidifying it) and by reclaiming moisture from the air before it is exhaled (as occurs most efficiently in camels).
For this reason, the area from the corners of the mouth to the bridge of the nose, including the nose and maxilla, is known to doctors as the danger triangle of the face.
The Nose - Wikipedia, the free encyclopedia (476 words)
The Nose is a satirical short story by Nikolai Gogol, subsequently made into an opera by Dmitri Shostakovich.
Kovalyov's joy is cut short when he finds that he is unable to re-attach the nose, even with the help of the doctor.
Peace also notes that some critics have interpreted the story as referring to a castration complex: the removal of Kovalyov's nose (and its developing a mind of its own) threaten both his chances of acquiring a position of power and of being a success with women.
