Where is the frontal nerve located?
The frontal nerve enters the orbit through the superior orbital fissure, above the muscles of the eyeball, and passes anterior on the levator palpebrae superioris. The frontal nerve divides into two branches, although the point of division is highly variable.
What does the frontal nerve innervate?
The two branches of the frontal nerve provide sensory innervation to the skin of the forehead, mucosa of the frontal sinus (an air sinus), and the skin of the upper eyelid.
What is the distribution of the trigeminal nerve?
The spinal nucleus of the trigeminal nerve has a pontomedullary distribution, extending along the full length of the medulla oblongata (from the caudal end of the main sensory nucleus of the trigeminal nerve) to the proximal spinal cord (about the second or third cervical segment).
What is the path of the trigeminal nerve?
The ophthalmic, maxillary, and mandibular branches of the trigeminal nerve leave the skull through 3 separate foramina: the superior orbital fissure, the foramen rotundum, and the foramen ovale, respectively. (See the image below.)
Where does lacrimal nerve come from?
The lacrimal nerve is the smallest of the main branches that arise from the ophthalmic nerve. Occasionally it will receive a fiber from the trochlear nerve. The lacrimal nerve then passes into the orbit through the superior orbital fissure, specifically its lateral part.
What nerve stimulates the frontal belly?
The vagus is the longest nerve of the autonomic nervous system in the human body and comprises sensory and motor fibers….

What nerves are in your forehead?
Sensory innervation of the forehead and anterior scalp is supplied by the supraorbital and supratrochlear nerves, being branches of the ophthalmic division of the trigeminal nerve. The supraorbital nerve and vessels emerge from the supraorbital foramen or notch and continue superiorly.
What nerve controls lacrimal?
Nerve supply The lacrimal gland is innervated by the lacrimal nerve, which is the smallest branch of the ophthalmic nerve, itself a branch of the trigeminal nerve (CN V). After the lacrimal nerve branches from the ophthalmic nerve it receives a communicating branch from the zygomatic nerve.
Where does the lacrimal nerve end?
It enters the lacrimal gland and gives off several filaments, which supply the gland and the conjunctiva. Finally it pierces the orbital septum, and ends in the skin of the upper eyelid, joining with filaments of the facial nerve.
