Coronal Section - head/sinusesYou selected: frontal sinusThe frontal air sinuses lie within the frontal bone of the forehead. The sinuses connect with the nasal passageways, and are involved in warming and moistening air destined for the lungs. Eating ice cream and other frozen foods rapidly cools the air in the frontal sinuses, triggering pain receptors, and producing that 'brain freeze' feeling. Approximate 3% of the population lacks frontal air sinuses.tongue | eye | nasal turbinates | maxillary sinus | frontal sinus | frontal lobe | olfactory_bulb | Information Module Name: 1704_head Module Title: Coronal Section - head/sinuses Image Info: Coronal section (1704) Visible Human Project Created by: Lynn Bry Contact Email:bryl@medicine.wustl.edu Last modified: January 23rd, 1997.
