Cranial bones contain air spaces. These air spaces are known as skeletal pneumaticity. Bird bones are all filled with air spaces.
Air-filled spaces in bones are called sinuses. These are hollow cavities within the bones that help to reduce the bone's weight while maintaining strength. The most well-known sinuses are the paranasal sinuses, found in the skull bones surrounding the nasal cavity.
During a mastoidectomy, the mastoid air cells located in the mastoid bone are removed. These air cells are typically removed to treat chronic ear infections or other diseases that affect the mastoid bone which houses these cells.
Air, fat, muscle, blood, liver, bone. The order is based on increasing radiodensity, with air being the least dense and bone being the most dense.
The petrous part of the temporal bone encloses the structures of the inner ear. Inside the tympanic cavity within the petrous part is the middle ear. The external acoustic canal ends at the tympanic membrane, which leads to the inner ear. Mastoid air cells within the mastoid process are connected to the tympanic cavity.
Ah, I see you're curious about the slim long bone beneath the ear. That would be the jawbone, also known as the mandible. It's a strong and important bone that helps us with tasks like chewing and speaking. Just like in painting, every detail, no matter how small, plays a vital role in creating the beauty of the whole picture.
Not necessarily. Scoria and pumice are forms of volcanic glass that contain air spaces, while obsidian, another volcanic glass, contains minimal air spaces if any.
tissue
Yes. Porous soil contains more air spaces between the particles, which is needed by burrowing animals such as worms. Water tends to fill these spaces, but even wet soil and sand may contain small air pockets.

the spongy layer has alot of air spaces so gases can diffuse in and out of the leaf easily
An air-filled bony cavity is a hollow space within a bone that contains air. These cavities are found in certain bones like the sinuses of the skull, where they help to reduce the weight of the bone and resonate sound.
It contains air spaces (aerenchyma) within the cells of the petiole
Yes, soil contains air in the pore spaces between soil particles. This air is crucial for the survival of soil-dwelling organisms and for the exchange of gases needed for plant roots to carry out respiration.
It's the same thing as a hollow bone. That's one of the characteristics birds posse than enables them to fly (if their bones had the same weight as ours, they wouldn't be able to lift). Some dinosaurs had the same type of bones. Hope it helped.

Plenum
A hollowbone is basically a bone with air pockets inside at the center, instead of bone tissue. This type of bone is usually found in birds.
