The external nasal nerve passes inferior-ward through the lateral nasal wall. It provides sensory innervation to the area of skin of the nose between the nasal bones superiorly and the tip of the nose inferiorly (excluding the alar portion surrounding the external nares). [1]
Since both the short and long ciliary nerves carry the afferent limb of the corneal reflex, one can test the integrity of the nasociliary nerve (and, ultimately, the trigeminal nerve) by examining this reflex in the patient. Normally both eyes should blink when either cornea (not the conjunctiva, which is supplied by the adjacent cutaneous ...
The nasal dorsum also known as the nasal ridge is the border between the root and the tip of the nose, which in profile can be variously shaped. [17] The ala of the nose (ala nasi, "wing of the nose"; plural alae) is the lower lateral surface of the external nose, shaped by the alar cartilage and covered in dense connective tissue. [1]
Both crus come together to form an oval tip at each nostril. Both sides of the major alar cartilages merge together to form a notch at the tip, which is referred to as the apex of the nose. With the formation of the medial and lateral walls within the nares, the major alar cartilages function to hold open each naris.
The nasalis muscle is a sphincter-like muscle of the nose. It has a transverse part and an alar part. It compresses the nasal cartilages, and can "flare" the nostrils. It can be used to test the facial nerve (VII), which supplies it.
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 ...
Seeing how the nose is the most prominent feature on a person’s face since it sits right between one’s eyes, Arbeau reveals it can be a common way for spirits of the deceased, angels, guides ...
The infraorbital nerve provides sensory innervation to the skin of the lower eyelid, [2] the side of the nose, [2] the moveable part of nasal septum, [citation needed] the anterior cheek, [citation needed] and part of the upper lip. [2] It does not provide motor supply to any muscles. [citation needed]
