maxillary nerve. Identifiers. Latin. rami nasales posteriores superiores (mediales [1] et laterales [2]) Anatomical terms of neuroanatomy. [ edit on Wikidata] 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 ...
The human nose is the first organ of the respiratory system. It is also the principal organ in the olfactory system. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two.
The nasopalatine nerve (also long sphenopalatine nerve [1] : 496 ) is a nerve of the head. It is a sensory branch of the maxillary nerve (CN V 2) that passes through the pterygopalatine ganglion (without synapsing) and then through the sphenopalatine foramen to enter the nasal cavity, and finally out of the nasal cavity through the incisive canal and then the incisive fossa to enter the hard ...
Sensory innervation to the head and neck. The external nasal nerve can be seen emerging from beneath the nasal bone (see tip of black arrow). The external nasal nerve is the terminal branch of the anterior ethmoidal nerve (its continuation beyond the inferior border of the nasal bone).
Nerves of septum of nose. Right side. (Nasociliary is rightmost yellow line.) The nasociliary nerve is a branch of the ophthalmic nerve (CN V 1) (which is in turn a branch of the trigeminal nerve (CN V) ). It is intermediate in size between the other two branches of the ophthalmic nerve, the frontal nerve and lacrimal nerve.

The nasal cycle is an alternation in both time and between left and right sides, with the total resistance in the nose remaining constant. The asymmetric airflow may have some benefit to overall olfactory sensitivity. [7] In patients with a fixed septal deviation and intermittent nasal obstruction, the interplay of the nasal cycle becomes ...
The nasal cartilages associate with other cartilage structures of the nose or with bones of the facial skeleton. These associations create vent-like structures within the nose so that air can flow from the nasal cavity to the lungs or vice versa. Therefore, the nasal cartilages are structures that aid the body in respiratory functions to intake oxygen or expire carbon dioxide.
Internal nasal branches of infraorbital nerve. Details. From. infraorbital nerve. Identifiers. Latin. rami nasales interni nervi infraorbitalis. TA98. A14.2.01.062.
The Inferior posterior nasal branches of greater palatine nerve are small nerves which largely supply the posterior aspect of the nasal cavity. They pass through small foramina in the palatine canal to supply the lateral walls of the nasal cavity - including the superior, middle, and inferior nasal concha. These nerves run alongside the lateral ...
