During chewing, food releases certain chemicals that enter the nose and activate olfactory receptors in the nose. They work in coordination with the taste buds to identify the actual taste of the food. Lateral wall of the nasal cavity with the location of the nasal turbinates and their continuation with the vestibule An oval bony chamber of the inner ear, part of the bony labyrinth. It is continuous with the anterior bony cochlea and semicircular posterior ducts. The vestibule contains two communicating bags (utricles and saccules) of the balancing apparatus. The oval window on its side wall is occupied by the base of the middle ear stirrups. Ear: anterior anatomy and nasopharyngeal nasopharynx The upper part of the pharynx is behind the nose and above the soft palate. The nasopharynx is the posterior extension of the nasal cavities and has a respiratory function. Pharynx: posterior anatomy After ten weeks, the cells differentiate into muscle, cartilage and bone.
Problems at this stage of development can cause birth defects such as choanal atresia (missing or closed passage), facial cleft and nasal dysplasia (defective or incomplete development) or, extremely rarely, polyrrhinia, the formation of a double nose.  Schematic representation of the external nose with external nasal cues, its bone and cartilaginous components, and the anterior nasal opening 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 produce a more developed nasal bridge or “high nose”.  Similarly, “DIY nose lifts” have become popular in the form of reusable cosmetics and are sold in many Asian countries such as China, Japan, South Korea, Taiwan, Sri Lanka and Thailand.    A raised nose was a common ideal of beauty in many Asian cultures, dating back to the beauty ideals of ancient China and India.   The nose supports many bodily functions, ranging from the vital process of breathing to improving flavor. The nasal cavity is divided by the nasal septum into two cavities, each accessible through an external nostril.   The division into two cavities allows the nasal cycle to function, which slows down the process of conditioning the inhaled air.
 At the back of the nasal cavity, there are two openings, called choane (also posterior nostrils), that give access to the nasopharynx and the rest of the airways.  Blood supply to the nose is through the branches of the eye, the maxillary and facial arteries – branches of the carotid arteries. The branches of these arteries anastomose to the plexuses in and under the nasal mucosa.  In the septum area, the Kiesselbach plexus is a common site of nosebleeds. The nose allows you to make perfumes of what is happening in the world around you. Just as your eyes give you information through sight and your ears help you hear, you can use your nose to find out what‘s going on by smell. It does this with the help of many parts hidden deep in your nasal cavity and head. The nasal septum, the flat cartilage plate in the middle nose, may be damaged and pushed left or right, or the nose may become crooked.
This condition is called a nasal septum. A deviant septum can cause breathing problems and discomfort because one or both nasal chambers are smaller than they should be. Sometimes a deviant septum is corrected by surgery. The bone structure of the nose is provided by the upper jaw, frontal bone and a number of smaller bones.  Further down the nose are even smaller hairs called cilia (pronounced: SILL-ee-uh), which you can only see with a microscope. The cilia move back and forth to move mucus from the sinuses and back of the nose. Cilia can also be found lining the airways, where they help move mucus out of the lungs. Miquel Hernández of the Department of Animal Biology at the University of Barcelona said that the “high and narrow nose of Eskimos and Neanderthals” is an “adaptation to a cold and dry environment” because it helps to warm and humidify the air and “recover heat and moisture from the exhaled air”.  The nose is the main olfactory organ and acts as an important respiratory organ in the body.
In addition, it is also involved in functions such as tasting. Normal development is crucial because the newborn breathes through the nose for the first six weeks and any nasal congestion requires emergency treatment to eliminate it.  The shape of the nose varies greatly due to differences in the shapes of the nasal bone and the formation of the bridge of the nose. Some nose shapes have been classified for surgery by Eden Warwick in nasology. These were then incorporated into a nasal index by Paul Topinard. Anthropometric studies have contributed significantly to craniofacial surgery, and nasal index is a recognized anthropometric index used in nasal surgery.  A large quantity of cookies comes out of the oven. Your gym bag filled with dirty clothes. How do you smell these smells and thousands more? It‘s your nose, of course. The two openings in nasal care are called nostrils or neck. They lead to two nasal cavities separated by the septum, a wall of cartilage.
Inside the face is a complex system of ducts and air pockets called sinuses. The sinus cavities extend to the back of the skull, just above the oral cavity, into the cheekbones and between the eyes and eyebrows. All these areas are at least partially responsible for breathing, smell, taste and defense of the immune system. Things coming out of the nose can be a problem. A runny nose is caused by the production of mucus in the nose. Mucus production can be triggered by anything that irritates or inflames the nose, such as allergies, a cold, flu or dust, according to the Mayo Clinic. Bloody noses occur when the tiny blood vessels in the nose break due to dry air, irritants, chemicals, bumps in the nose, and various other factors. The human nose is the protruding part of the face.
It carries the nostrils and is the first organ of the respiratory tract. It is also the main organ of the olfactory system. The shape of the nose is determined by the nasal bones and nasal cartilage, including the nasal septum, which separates the nostrils and divides the nasal cavity into two parts. On average, the nose of a male is larger than that of a female. To learn more about the structure and function of the nose, visit the BYJU website or download the BYJU app for another reference. It has been suggested that variations in nose shape may have been adapted to regional differences in temperature and humidity, although they may also have been caused by other factors such as sexual selection.  These receptors are very small – there are about 10 million in the nose! There are hundreds of different olfactory receptors, each with the ability to perceive certain odorous molecules. Research has shown that an odor can stimulate different types of receptors. The brain interprets the combination of receptors to recognize one of some 10,000 different smells.
