@atomedgeanatomy: Did you know that you have built-in air pockets in your skull? They're called paranasal sinuses. There are four main pairs: frontal (forehead), maxillary (cheeks), ethmoid (between the eyes), and sphenoid (deep behind the nose). They lighten the weight of your skull, warm and humidify the air you breathe, and add resonance to your voice. They also produce mucus to trap dust and pathogens... and yes, they’re the reason your face feels heavy and pressurized during a sinus infection.. #anatomy #medicalanimation #paranasalsinuses #sinusesdraining #anatomystudy
