A sinus is an air cavity in bone.
The prominent bony ridges on the lateral walls of the nasal cavity are called the turbinates or nasal conchae. They help increase the surface area of the nasal cavity to facilitate warming, humidifying, and filtering of the air before it reaches the lungs.
The pelvic cavity is partially enclosed by the bony pelvis and contains the reproductive organs, bladder, and rectum.
The most protective body cavity is the cranial cavity, which houses and protects the brain. The skull surrounds the brain providing a strong bony structure and a layer of cerebrospinal fluid acts as a cushion to protect the brain from impact and injury.
The bony landmarks are: iliac crest (a good place to put you hands on), anterior superior iliac spine (that "bump" you can feel on either side of your stomach if it is flat), symphysis pubis (between the legs), sacral promontory which you can not feel but is above the leaf shaped tail bone called the sacrum. Plus the lower ribs and end of the sternum.
The glenoid cavity is a shallow depression on the scapula where the head of the humerus articulates to form the shoulder joint. The acromion is a bony process of the scapula that forms the point of the shoulder and articulates with the clavicle to stabilize the shoulder joint.
The bony nasal cavity is made up of the hard palate and the palatine process of the maxilla. The nasal cavity is made up of the rest of the nasal sinuses and includes the bony nasal cavity.
NAME THE VENTRAL CAVITY THAT HAS NO BBONY PROTECTION
rib cage
The palate is defined as the combination of the hard and soft palate. The hard palate, the anterior bony portion, separates the oral cavity from the nasal cavity.
is the auditory portion of the ear. It is a spiral-shaped cavity in the bony labyrinth.
The prominent bony ridges on the lateral walls of the nasal cavity are called the turbinates or nasal conchae. They help increase the surface area of the nasal cavity to facilitate warming, humidifying, and filtering of the air before it reaches the lungs.

my history teacher says its a septum .. i don't know if that's how you spell it though :)
An antrostomy is an incision and drainage of the antrum, a bodily cavity, especially one with bony walls such as the sinuses.
The pelvic cavity is partially enclosed by the bony pelvis and contains the reproductive organs, bladder, and rectum.
The most protective body cavity is the cranial cavity, which houses and protects the brain. The skull surrounds the brain providing a strong bony structure and a layer of cerebrospinal fluid acts as a cushion to protect the brain from impact and injury.
The bony ridges that warm the air as it travels through the nasal cavity are called turbinate bones or nasal conchae. They help to increase the surface area of the nasal cavity to aid in warming, humidifying, and filtering incoming air before it reaches the lungs.
