The inferior concha is the largest of the nasal conchae and can easily be seen when looking into the anterior opening of the nasal cavity. Fatal drug overdoses have spiked in recent years. Each nasal bone has four bones, which form joints: The zygomatic arch is the bony arch on the side of skull that spans from the area of the cheek to just above the ear canal. Research confirms that good moods are contagious. The largest region of each of the palatine bone is the horizontal plate. Cleft palate affects approximately 1:
How many individual bones contribute to the facial skeleton? The palatine bones form the posterior portion of the roof of the mouth, part of the orbits, and part of the inferior wall of the nasal cavity. The Autonomic Nervous System The ethmoid bone and lacrimal bone make up much of the medial wall and the sphenoid bone forms the posterior orbit. Additional causes vary, but prominent among these are automobile and motorcycle accidents.

The middle fossa extends from the lesser wing of the sphenoid bone anteriorly to the petrous ridge posteriorly. View this animation to see how a blow to the head may produce a contrecoup counterblow fracture of the basilar portion of the occipital bone on the base of the skull. From anterior to posterior, the fossae increase in depth. It raises your eyebrows and helps you frown. Additional causes vary, but prominent among these are automobile and motorcycle accidents. The small superior nasal concha is well hidden above and behind the middle concha.

A blow to the lateral side of the head may fracture the bones of the pterion. Your frontalis muscle runs vertically along your forehead. The frontal sinus is the most anterior of the paranasal sinuses. Projecting downward are the medial and lateral pterygoid plates. Metabolism and Nutrition On the lateral side of the brain case, above the level of the zygomatic arch, is a shallow space called the temporal fossa.
