Anatomical terms of neuroanatomy

The posterior ethmoidal nerve is a nerve of the orbit around the eye. It is a branch of the nasociliary nerve from the ophthalmic nerve (CN V1). It supplies sensation to the sphenoid sinus, the ethmoid sinus, and part of the dura mater in the anterior cranial fossa.

Contents

Structure

The posterior ethmoidal nerve is a branch of the nasociliary nerve, itself a branch of the ophthalmic nerve (CN V1), itself a branch of the trigeminal nerve (CN V). [1] It passes through the posterior ethmoidal foramen, with the posterior ethmoidal artery. [2] It gives branches to the sphenoid sinus and the ethmoid sinus. [1] It also gives a branch to supply part of the dura mater in the anterior cranial fossa. [3] [4]

Variation

The posterior ethmoidal nerve is absent in a significant proportion of people. [5] This may be around 30%.

Function

The posterior ethmoidal nerve supplies sensation to the sphenoid sinus and the ethmoid sinus. [1] It also supplies sensation to part of the dura mater in the anterior cranial fossa. [3] [4]

Other animals

The posterior ethmoidal nerve is present in other animals, including horses. [6] [7] Headshaking can sometimes be treated with analgesia or neurectomy of the posterior ethmoidal nerve. [7]

<span class="mw-page-title-main">Paranasal sinuses</span> Group of four paired air-filled spaces that surround the nasal cavity

Paranasal sinuses are a group of four paired air-filled spaces that surround the nasal cavity. The maxillary sinuses are located under the eyes; the frontal sinuses are above the eyes; the ethmoidal sinuses are between the eyes and the sphenoidal sinuses are behind the eyes. The sinuses are named for the facial bones in which they are located.

<span class="mw-page-title-main">Sphenoid bone</span> Bone at the front of the skull

The sphenoid bone is an unpaired bone of the neurocranium. It is situated in the middle of the skull towards the front, in front of the basilar part of the occipital bone. The sphenoid bone is one of the seven bones that articulate to form the orbit. Its shape somewhat resembles that of a butterfly or bat with its wings extended.

<span class="mw-page-title-main">Nasal cavity</span> Large, air-filled space above and behind the nose in the middle of the face

The nasal cavity is a large, air-filled space above and behind the nose in the middle of the face. The nasal septum divides the cavity into two cavities, also known as fossae. Each cavity is the continuation of one of the two nostrils. The nasal cavity is the uppermost part of the respiratory system and provides the nasal passage for inhaled air from the nostrils to the nasopharynx and rest of the respiratory tract.

<span class="mw-page-title-main">Orbit (anatomy)</span> Cavity or socket of the skull in which the eye and its appendages are situated

In anatomy, the orbit is the cavity or socket of the skull in which the eye and its appendages are situated. "Orbit" can refer to the bony socket, or it can also be used to imply the contents. In the adult human, the volume of the orbit is 30 millilitres, of which the eye occupies 6.5 ml. The orbital contents comprise the eye, the orbital and retrobulbar fascia, extraocular muscles, cranial nerves II, III, IV, V, and VI, blood vessels, fat, the lacrimal gland with its sac and duct, the eyelids, medial and lateral palpebral ligaments, cheek ligaments, the suspensory ligament, septum, ciliary ganglion and short ciliary nerves.

<span class="mw-page-title-main">Superior orbital fissure</span> Foramen in the skull allowing for passage of cranial nerve

The superior orbital fissure is a foramen or cleft of the skull between the lesser and greater wings of the sphenoid bone.

The foramen spinosum is a hole located in the greater wing of the sphenoid. It is located posterolateral to the foramen ovale and anterior to the sphenoidal spine. It allows the passage of the middle meningeal artery, middle meningeal vein and usually the meningeal branch of the mandibular nerve.

<span class="mw-page-title-main">Ophthalmic nerve</span> Sensory nerve of the face

The ophthalmic nerve (V1) is a sensory nerve of the face. It is one of three divisions of the trigeminal nerve (CN V). It has three branches that provide sensory innervation to the eye, the skin of the upper face, and the skin of the anterior scalp.

<span class="mw-page-title-main">Nasociliary nerve</span> Branch of the ophthalmic nerve

The nasociliary nerve is a branch of the ophthalmic nerve (CN V1) (which is in turn a branch of the trigeminal nerve (CN V)). It is intermediate in size between the other two branches of the ophthalmic nerve, the frontal nerve and lacrimal nerve.

<span class="mw-page-title-main">Superior ophthalmic vein</span> Vein of the orbit around the eye

The superior ophthalmic vein is a vein of the orbit that drains venous blood from structures of the upper orbit. It is fromed by the union of the angular vein, and supraorbital vein. It passes backwards within the orbit alongside the ophthalmic artery, then exits the orbit through the superior orbital fissure to drain into the cavernous sinus.

The sphenoid sinus is a paired paranasal sinus occurring within the within the body of the sphenoid bone. It represents one pair of the four paired paranasal sinuses. The pair of sphenoid sinuses are separated in the middle by a septum of sphenoid sinuses. Each sphenoid sinus communicates with the nasal cavity via the opening of sphenoidal sinus. The two sphenoid sinuses vary in size and shape, and are usually asymmetrical.

<span class="mw-page-title-main">Zygomatic nerve</span> Nerve of the face

The zygomatic nerve is a branch of the maxillary nerve, itself a branch of the trigeminal nerve. It travels through the orbit and divides into the zygomaticotemporal and the zygomaticofacial nerve. It provides sensory supply to skin over the zygomatic bone and the temporal bone. It also carries postganglionic parasympathetic axons to the lacrimal gland. It may be blocked by anaesthetising the maxillary nerve.

<span class="mw-page-title-main">Anterior ethmoidal artery</span>

The anterior ethmoidal artery is a branch of the ophthalmic artery in the orbit. It exits the orbit through the anterior ethmoidal foramen alongside the anterior ethmoidal nerve. It contributes blood supply to the ethmoid sinuses, frontal sinuses, the dura mater, lateral nasal wall, and masal septum. It issues a meningeal branch, and nasal branches.

<span class="mw-page-title-main">External nasal nerve</span>

The external nasal nerve is a terminal branch of the anterior ethmoidal nerve. The trigeminal nerve branches into three nerves, one of which is the ophthalmic nerve, which itself has three branches, one of which is the nasociliary nerve. One of the terminal branches of the nasociliary nerve is the anterior ethmoidal nerve. The anterior ethmoidal nerve divides into a lateral nasal branch and medial nasal branch.The medial nasal branch after giving off sensory branches to the anterior and upper parts of the nasal septum, emerges from beneath the inferior nasal margin to form the external nasal nerve. The external nasal nerve provides sensory innervation to the skin of the external nose to the tip.
