No, the choanae are the same as the internal nares, just posterior to the nasal meatuses.

Medullary Cavity. Answer for canal-like structure in the bone is : MEATUS.
urethral meatus, The urethra is the tube leading from the bladder to the meatus to discharge urine outside the body.
The opening of the urethra is the external urethral orifice.
The passageways are called the inferior meatus, the middle meatus and the superior meatus.
No, external auditory meatus and external acoustic meatus refer to the same structure, which is the ear canal that leads from the outer ear to the eardrum.
Meati (plural) for superior, middle and inferior meatus.

The plural of meatus is meatuses or meatus - both forms are accepted.
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.
A meatus is a tubular opening or passage in the body.
Medullary Cavity. Answer for canal-like structure in the bone is : MEATUS.
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.
Any passage or opening leading to the interior of the body is known as a meatus. The external opening through which urine passes out of the body is called the urinary meatus.
