What does the zygomatic nerve control?

What does the zygomatic nerve control?

(2) The pterygopalatine group includes the zygomatic nerve, which provides sensory innervation to the temporal and lateral zygomatic region, and the sphenopalatine branches, which help to innervate the mucosa of the maxillary sinus, upper gums, upper molars, and mucous membranes of the cheek.

What does the zygomatic branch of the facial nerve innervate?

The zygomatic branch – innervating the middle part of the face. The buccal branch – innervating the cheek muscles, including the buccinator muscle. The mandibular branch – innervating muscles of the lower part of the face.

What does the lacrimal nerve do?

Function. The lacrimal nerve provides sensory innervation to the lacrimal gland, conjunctiva of the lateral upper eyelid and superior fornix, the skin of the lateral forehead, scalp and lateral upper eyelid.

What nerve Innervates lacrimal glands?

trigeminal nerve
The lacrimal gland receives sensory, parasympathetic, as well as sympathetic innervation. The lacrimal nerve, from the ophthalmic branch of the trigeminal nerve provides sensory innervation to the gland.

Where does the lacrimal nerve pass?

Inside the lacrimal gland, the lacrimal nerve goes off a few small fibers to the gland itself but also to the skin of the upper eyelid. It then passes into the orbital septum and terminates in the skin of the upper eyelid, where it will ramify with branches of the facial nerve.

Where does the lacrimal nerve originate?

the pterygopalatine ganglion
Originating from the pterygopalatine ganglion, these communicating fibers consist of postganglionic parasympathetic secretomotor axons for the lacrimal gland (Shankland, 2001a).

How long does it take for the 7th cranial nerve to heal?

Natural Healing Time Expect no noticeable signs of healing before about four to six months after the damage occurs. Everyone is different it might take more or less time, but the majority of the healing that will occur on its own will be in the first year.

Where does the zygomatic nerve enter the lacrimal gland?

In the orbit it runs along the upper border of the lateral rectus, with the lacrimal artery, and communicates with the zygomatic nerve, a branch of the maxillary nerve. It enters the lacrimal gland and gives off several filaments, which supply sensory innervation to the gland and the conjunctiva.

What does the zygomatic nerve innervate?

The zygomatic nerve emerges from the inferior orbital fissure and courses superiorly on the lateral orbital wall. Current dogma indicates that postganglionic parasympathetic fibers from the facial nerve (CNVII) run in this nerve, branch off in the lateral orbit, and enter the lacrimal nerve to provide secretomotor innervation to the lacrimal gland.

Is the lacrimal nerve visible?

Nerves of the orbit, the lacrimal nerve is visible, labelled over the eye. The lacrimal nerve is the smallest branch of the ophthalmic nerve (V 1 ), itself a branch of the trigeminal nerve (CN V). The other branches of the ophthalmic nerve are the frontal nerve and nasociliary nerve.

What nerve anastomoses with the lacrimal nerve?

The lacrimal nerve anastomoses with the trochlear nerve and the orbital branch of the maxillary nerve. Some of these terminal branches enter the lacrimal gland; others extend to the lateral aspect of the superior eyelid.
