Nose - In mammals. In most mammals, 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. Nose as a term may be used to designate the leading end ...

A nostril is one of the two channels of the nose, from the point where they bifurcate to the external opening. In birds and mammals they contain branched bones or cartilages called turbinates whose function is to warm air on inhalation and remove moisture on exhalation. Fish do not breathe through their noses, but they do have two small holes used for smelling which may be called nostrils. The nostrils of some whales are highly asymmetric, one nostril proceeding straight diagonally up to the blowhole, the other detouring to the back of the head. This is thought to give an evol ...

The vomeronasal organ (VNO) or Jacobson's organ is an auxiliary olfactory sense organ in some tetrapods. In adults, it is located in the vomer bone, between the nose and the mouth. It develops from the nasal (olfactory) placode, at the anterior edge of the neural plate. Its function is somewhat mysterious. The sensory neurons within the vomeronasal organ detect distinct chemical compounds, often but not always large molecules. The vomeronasal organ is used in the detection of pheromones in some animals such as mic ...

Aircraft attitude is used to mean two closely related aspects of the situation of an aircraft in flight. In the simplest use it is the orientation of an aircraft with respect to the horizon. This is a function of two angles: pitch and roll. The pitch angle specifies the orientation of the aircraft's longitudinal axis, that is, whether the nose is pointing upwards, is level to the horizon, or is pointing downwards. The roll angle specifies whether the aircraft is banked left or right, or whether its wings are parallel to the hor ...

The recovery sequence begins with the operation of the high-altitude baroswitch, which triggers the functioning of the pyrotechnic nose cap thrusters. This ejects the nose cap, which deploys the pilot parachute. Nose cap separation occurs at a nominal altitude of 15,704 feet (4,787 m) about 218 seconds after SRB separation. The 11.5-foot (3.5 m) diameter conical ribbon pilot parachute provides the force to pull lanyards attached to cut knives, which cut the loop securing the drogue retention straps. This allows the pilot chute to pull the dr ...

One controversial objective of body modification is the attempt to resemble another race, such as Asians having their epicanthal folds modified to resemble non-Asian eyes or skin lightened with dyes (or even surgically), suntanning, increase in lips, or buttocks size by Caucasians, or African-Americans straightening their hair or getting a nose job. "Disfigurement" (a subjective term) and "mutilation" (regardless of any appreciation this always applies objectively whenever a bodily function is gravely diminished or lost, as with castr ...

Most tissue histamine is found in granules in mast cells or basophils. Mast cells are especially numerous at sites of potential injury - the nose, mouth, and feet; internal body surfaces; and blood vessels. Non-mast cell histamine is found in several tissues, including the brain, where it functions as a neurotransmitter. Another important site of histamine storage and release is the enterochromaffin-like (ECL)cell of the stomach. The most important pathophysiologic mechanism of mast cell and basophil histamine release is immunologic. ...

People with faces disfigured by burns, trauma, disease or birth defects might benefit from the procedure. The alternative to a face transplant is to move the patient's own skin from their back, buttocks or thighs to their face in a series of as many as 50 operations to regain even limited function and a face that is often likened to a mask or a living quilt. Dr. L. Scott Levin, chief of plastic and reconstructive surgery at the Duke University Medical Center, has described the procedure as "the single most ...

There are three basic types of motorcycle helmets. From most to least protective, they are: Full face  A full face helmet covers the entire head, with a rear that covers the base of the skull, and a protective section over the front of the chin. Such helmets have an open cutout in a band across the eyes and nose, with a plastic face shield (which may be clear or tinted) that generally swivels up and down to allow access to the face. Many full face helmets include vents to increase the airflow to the rider. The sign ...

As their name suggests, nerve agents attack the nervous system of the human body. All such agents function the same way: by interrupting the breakdown of the neurotransmitters that signal muscles to contract, preventing them from relaxing. Initial symptoms following exposure to sarin (and other nerve agents) are a runny nose, tightness in the chest and constriction of the pupils. Soon after, the victim will then have difficulty breathing, and will experience nausea and drooling. As the victim continues to lose control of his or her bo ...

Definition and meaning of melon:

melon - a lens-shaped fatty deposit lying in the facial depression of many toothed whales, such as the bottle-nosed dolphin. It appears as the bulging forehead just in front of the blowhole. It contains fatty deposits, muscles, and nasal air sacs and passages. The melon is used in focusing a whale's sounds, functioning as an acoustical lens for echolocation.The fatty deposits change shape as the whale is producing sounds
