What does the zygomatic nerve innervate?

(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.

Where does the maxillary nerve innervate?

In sum, the maxillary nerve innervates the skin of the lower eyelid, the prominence of the cheek, the alar part of the nose, part of the temple, and the upper lip (Figures 2.2 and 2.3).

Which nerve provides motor innervation of the face?

facial nerve
The facial nerve provides motor innervation of facial muscles that are responsible for facial expression, parasympathetic innervation of the glands of the oral cavity and the lacrimal gland, and sensory innervation of the anterior two-thirds of the tongue.

What is the function of the maxillary nerve?

The maxillary nerve is the second branch of the trigeminal nerve, which originates embryologically from the first pharyngeal arch. Its primary function is sensory supply to the mid-third of the face.

Is the zygomaticus major innervated by the facial nerve?

Zygomaticus major is innervated by the zygomatic and buccal branches of facial nerve (CN VII). Learning the anatomy of over 600 muscles can be a daunting task. Ease your studies, master examinable subjects in your upcoming anatomy exams and become efficient using Kenhub’s muscle anatomy and reference charts!

How does the zygomatic nerve compensate for missing nerve fibers?

Either branch of the zygomatic may be absent or smaller than normal, in which case the other branch compensates by carrying the additional nerve fibers. The area usually supplied by the zygomatic branch (skin of the zygomatic region) may be supplied instead by the infraorbital nerve.

Where does the zygomatic nerve enter the orbit?

The zygomatic nerve arises in the pterygopalatine fossa. It enters the orbit by the inferior orbital fissure, and divides at the back of that cavity into two branches, the zygomaticotemporal nerve and zygomaticofacial nerve, which exit the orbit using identically named foramina.

Is the zygomatic nerve in the ciliary ganglion?

Zygomatic nerve. Nerves of the orbit, and the ciliary ganglion. (Zygomatic nerve labeled at bottom center.) The zygomatic nerve ( temporomalar nerve; orbital nerve) is a branch of the maxillary nerve (CN V 2, itself a branch of the trigeminal nerve) that enters the orbit and helps to supply the skin over the zygomatic and temporal bones .
