What is the fleshy part of the nose called?
Parts of human nose - External structureNasal bones - two oblong shaped bones which connect vertically and run from the top to the middle of the nose. They form the bridge of the nose and vary in size depending on the individual.Septal Cartilage (quadrangular cartilage) - adjoins the nasal bones at their inferior border and forms the dividing wall of the nose. Situated at the anterior margin of the ethmoid bone.Lateral nasal cartilage - this dense connective tissue is situated below the nasal bones and the frontal process of the maxilla.

What is the girls pee area called?
urethral meatus, The urethra is the tube leading from the bladder to the meatus to discharge urine outside the body.

Is the superior nasal conchae found in the ethmoid?
the back part of the medial surface of the labyrinth of ethmoid is subdivided by a narrow oblique fissure, the superior meatus of the nose, bounded above by a thin, curved plate, the superior nasal conchae.The bone found in superior nasal concha is part of the ethmoid bone.See also

Medullary Cavity. Answer for canal-like structure in the bone is : MEATUS.

The passageways are called the inferior meatus, the middle meatus and the superior meatus.
What is the space between the middle and inferior nasal conchae?
The space between the middle and inferior nasal conchae is known as the inferior meatus. It is a passage for air to flow through the nasal cavity and plays a role in humidifying and filtering the air we breathe.
Is there a difference between external auditory meatus and external acoustic meatus?
The external auditory meatus and the external acoustic meatus are two names for the same structure.
Where do maxillary sinuses drain?
The maxillary sinuses drain into the middle meatus of the nasal cavity through the semilunar hiatus.

What is the pleural of meatus?
The plural of meatus is meatuses or meatus - both forms are accepted.
What is the nasal conchae?
The nasal conchae are three pairs of bony projections in the nasal cavity. They are generally curved inferomedially with each roofing a groove or meatus. It helps to filter, heat and moisten inhaled air and minimize heat and moisture loss from the body during exhalation.

It's an intricate network of bones, cartilage plates, cells and nerve endings.
What is a meatus?
A meatus is a tubular opening or passage in the body.
Are your tear ducts connected to your sinuses?
Yes, tear ducts are connected to the sinuses through a system of small passages. The tear ducts drain tears from the eyes into the nasal cavity, specifically through the nasolacrimal duct, which empties into the inferior nasal meatus. This connection is why your nose may run when you cry, as excess tears can flow into the nasal passages.
Does the respiratory system warm air as it enters the body?
Yes it does. The nose is designed with conchae or turbinates that provide a pathway, meatus, that causes the air to touch the walls as it passes through. The nasal cavity is highly vascular, hence nose bleeds, that warm the air as it passes by.
