Ethmoidal cells

Anatomy The ethmoid bone gets its name from the ethmoid plate (lamina cribrosa), which like a sieve has numerous holes and is found in the facial skull (viscerocranium). The ethmoid bone (Os ethmoidale) is a bony structure between the two eye sockets (orbitae) in the skull. It forms one of the central structures of the … Ethmoidal cells

Swelling of the ethmoidal cells | Ethmoidal cells

Swelling of the ethmoidal cells In a healthy state, particles and germs in the mucus are transported by the cell movement, the cilia beat, towards the exit (ostium, ostiomeatal unit). During an inflammation of the ethmoid cells (sinusitis ethmoidalis) the mucosa (respiratory ciliated epithelium) of the ethmoid cells can swell. This swelling can close the … Swelling of the ethmoidal cells | Ethmoidal cells

Nasal mucosa

Anatomy The nasal mucosa is a thin layer of tissue that lines our nasal cavities from the inside. It is made up of certain skin cells, which have about 50 – 300 short brush-like nasal hairs, the so-called cilia. In addition, glands for secretion formation and venous plexuses for air flow regulation are embedded in … Nasal mucosa

Sinus frontalis (frontal sinus)

The frontal sinus (Sinus frontalis) belongs like the maxillary sinus, sphenoidal sinus and the ethmoid cells to the paranasal sinuses (Sinus paranasales). It represents an air-filled cavity in the bone that forms the forehead and, like the other parts of the paranasal sinuses, it can also become inflamed, which is known as sinusitis (see below). … Sinus frontalis (frontal sinus)

Nasal septum

Synonyms Nasal septum, septum nasi Anatomy The nasal septum divides the main nasal cavities into a left and a right side. The nasal septum thus forms the central boundary of the nostrils (nares). The nasal septum forms the externally visible shape of the nose with a posterior bony (vomer and lamina perpendicularis ossis ethmoidalis), a … Nasal septum

Maxillary sinus

Introduction The maxillary sinus (Sinus maxillaris) is the largest paranasal sinus in pairs. It is of very variable shape and size. The floor of the maxillary sinus often shows protrusions, which are caused by the roots of the small and large posterior teeth. The maxillary sinus is air-filled and lined with ciliated epithelium. There is … Maxillary sinus
