The superior labial branches (labial branches), the largest and most numerous, descend behind the Quadratus labii superioris, and are distributed to the skin of the upper lip, the mucous membrane of the mouth, and labial glands.

The levator labii superioris (or quadratus labii superioris) is a broad sheet, the origin of which extends from the side of the nose to the zygomatic bone.

Its medial fibers form the angular head

The upper lip covers the anterior surface of the body of the maxilla. It is referred to as the vermillion.

It is raised by the Levator labii superioris.

The mucous membranes (or mucosae; singular: mucosa) are linings of mostly endodermal origin, covered in epithelium, and are involved in absorption and secretion. They line various body cavities that are exposed to the external environment and internal organs.

The labial glands are situated between the mucous membrane and the Orbicularis oris, around the orifice of the mouth.

They are circular in form, and about the size of small peas; their ducts open by minute orifices upon the mucous membrane.

The facial nerve is the seventh (VII) of twelve paired cranial nerves. It emerges from the brainstem between the pons and the medulla, and controls the muscles of facial expression, and taste to the anterior two-thirds of the tongue.

Cranial nerves are nerves that emerge directly from the brain in contrast to spinal nerves which emerge from segments of the spinal cord. Although thirteen cranial nerves in humans fit this description, twelve are conventionally recognized.

The trigeminal nerve (the fifth cranial nerve, also called the fifth nerve or simply V) is responsible for sensation in the face. It is similar to the spinal nerves C2–S5, which are responsible for sensation in the rest of the body.

The ophthalmic nerve is one of the three branches of the trigeminal nerve, the fifth cranial nerve. Like the maxillary branch of the trigeminal nerve, the ophthalmic branch carries sensory fibers only.

The lacrimal nerve is the smallest of the three branches of the ophthalmic.

It sometimes receives a filament from the trochlear nerve, but this is possibly derived from the branch which goes from the ophthalmic to the trochlear nerve.

The frontal nerve is the largest branch of the ophthalmic, and may be regarded, both from its size and direction, as the continuation of the nerve.

It enters the orbit through the superior orbital fissure, and runs forward between the Levator palpebræ superioris and the

The supraorbital nerve is a terminal branch of the frontal nerve.

It passes through the supraorbital foramen, and gives off, in this situation, palpebral filaments to the upper eyelid.

The nasociliary nerve is a branch of the ophthalmic nerve. It is intermediate in size between the two other main branches of the ophthalmic nerve, the frontal nerve and the lacrimal nerve, and is more deeply placed.

The long root of the ciliary ganglion usually arises from the nasociliary between the two heads of the lateral rectus muscle. It is also called the nasociliary nerve's communicating branch to the ciliary ganglion.
..... Click the link for more information.

The long ciliary nerves, two or three in number, are given off from the nasociliary, as it crosses the optic nerve.

They accompany the short ciliary nerves from the ciliary ganglion, pierce the posterior part of the sclera, and running forward between it and the choroid,

The infratrochlear nerve is given off from the nasociliary just before it enters the anterior ethmoidal foramen.

It runs forward along the upper border of the medial rectus, and is joined, near the pulley of the superior oblique, by a filament from the supratrochlear nerve.

The posterior ethmoidal nerve is a branch of the nasociliary nerve.

It passes through the posterior ethmoidal foramen, with the posterior ethmoidal artery.

It carries sensory information from the sphenoid sinus and posterior ethmoidal air cells.

The anterior ethmoidal nerve is a nerve which provides sensory branches to the nasal cavity.^[1]

The ciliary ganglion is a parasympathetic ganglion located in the posterior orbit. It measures 1- 2 millimeters in diameter and contains approximately 2,500 neurons^[1]. Preganglionic axons from the Edinger-Westphal nucleus form synapses with these cells.

The branches of the ciliary ganglion are the short ciliary nerves.

These are delicate filaments, from six to ten in number, which arise from the forepart of the ganglion in two bundles connected with its superior and inferior angles; the lower bundle is the larger.

The middle meningeal nerve (meningeal or dural branch) is given off from the maxillary nerve directly after its origin from the semilunar ganglion

It accompanies the middle meningeal artery and supplies the dura mater.

The zygomatic nerve (temporomalar nerve; orbital nerve) is a branch of the maxillary nerve (a trigeminal nerve branch) that enters the orbit and helps to supply the skin over the zygomatic and temporal bones.

The zygomaticotemporal nerve or zygomaticotemporal branch (temporal branch) is derived from the maxillary branch of the trigeminal nerve (Cranial nerve 5). It runs along the lateral wall of the orbit in a groove in the zygomatic bone, receives a branch of communication from
