Cavernous Armpit

**Cavernous sinus** is an anatomical formation, which is a cavity at the upper wall of the nasal cavity in the lateral parts of the facial skull. On the sides it is limited by the eye sockets, and below by the cranial cavity and eye sockets. The superior edge of the cavernous sinus forms the superior wall of the nasal cavity. On the sides of the cavity, the pterygoid processes located there are attached at the junction with the body of the sphenoid bone.

The cavity (cavernous formation) is lined from the inside with a mucous membrane (on the side - by the internal carotid artery). The entrance to the cavernous sinus lies anteriorly and superiorly, and opens in the superior nasal meatus. In an adult, this sinus has an abundant blood supply, its walls pulsate due to fairly large arterial trunks and are richly vascularized. Down the sinus cavity communicates with the nasal cavity, where its openings open, as well as the lymph nodes. From this sinus, through veins up to 17 mm in diameter, blood flows directly into the internal jugular vein system.

Speaking about pathology, it should be said that abnormalities in the development of the body can lead to inflammation of the upper paranasal sinuses. Thus, organ pathology often leads to the development of diseases and conditions such as sinusitis: ethmoiditis,
