The alae of the nose are supplied by nasal branches of CN V 2, the infraorbital nerve, and internal nasal branches of infraorbital nerve that supply the septum and the vestibule. [46] [13] The maxillary sinus is supplied by superior alveolar nerves from the maxillary and infraorbital nerves.

General sensory innervation is by branches of the trigeminal nerve (V 1 and V 2): Nasociliary nerve (V 1) Anterior ethmoidal nerve from the nasociliary nerve (V 1) Posterior nasal branches of maxillary nerve (V 2) The nasal cavity is innervated by autonomic fibers.
Lateral wall of nasal cavity; the three nasal conchæ have been removed. (Sphenoidal sinus visible at upper right, in dark circle.) Nose and nasal cavities. (Sphenoid sinus labeled at upper right.) The sphenoid sinus is a paired paranasal sinus occurring within the body of the sphenoid bone.
The ( medial and lateral) posterior superior nasal nerves are branches of the maxillary nerve (CN V2) [3] : 496 that arise in the pterygopalatine fossa from pterygopalatine ganglion [3] : 369–370 and pass through the sphenopalatine foramen into the nasal cavity [3] : 496 to innervate the nasal septum (the medial nerves), and the ...
The frontal sinuses, superior to the eyes, in the frontal bone, which forms the hard part of the forehead. They are innervated by the ophthalmic nerve (CN V1). [2] The ethmoidal sinuses, which are formed from several discrete air cells within the ethmoid bone between the nose and the eyes.

The olfactory bulb transmits smell information from the nose to the brain, and is thus necessary for a proper sense of smell. As a neural circuit, the glomerular layer receives direct input from afferent nerves, made up of the axons from approximately ten million olfactory receptor neurons in the olfactory mucosa, a region of the nasal cavity.
The olfactory mucosa is the neuroepithelialial mucosa [1] lining the roof and upper parts of the septum and lateral wall of the nasal cavity [1] [2] which contains bipolar neurons of the primary receptor neurons of the olfactory pathway, as well as supporting cells.
Frontal sinus. Outline of bones of face, showing position of air sinuses. Frontal sinus is shown in green. The frontal sinuses are one of the four pairs of paranasal sinuses that are situated behind the brow ridges. Sinuses are mucosa -lined airspaces within the bones of the face and skull.
