Maxilla

In human anatomy, the infraorbital foramen is an opening in the maxillary bone of the skull located below the infraorbital margin of the orbit.
The Infraorbital foramen

Infraorbital artery

suborbital arteryinfraorbitalinfraorbital branch
It transmits the infraorbital artery and vein, and the infraorbital nerve, a branch of the maxillary nerve.
The infraorbital artery is an artery in the head that branches off the maxillary artery, emerging through the infraorbital foramen, just under the orbit of the eye.

Orbit (anatomy)

orbitorbitseye socket
In human anatomy, the infraorbital foramen is an opening in the maxillary bone of the skull located below the infraorbital margin of the orbit.
There is a supraorbital foramen, an infraorbital foramen, a superior orbital fissure, an inferior orbital fissure and the optic canal, each of which contains structures that are crucial to normal eye functioning.

Infraorbital vein

vein
It transmits the infraorbital artery and vein, and the infraorbital nerve, a branch of the maxillary nerve.
Accompanied by the infraorbital artery and the infraorbital nerve, it passes posteriorly through the infraorbital foramen, infraorbital canal, and infraorbital groove.

Infraorbital nerve

infra-orbital nerveinfraorbital portion
It transmits the infraorbital artery and vein, and the infraorbital nerve, a branch of the maxillary nerve.
This nerve innervates (sensory) the lower eyelid, upper lip, and part of the nasal vestibule and exits the infraorbital foramen of the maxilla.

Maxillary nerve

maxillarymaxillary divisionpalatine nerve
It transmits the infraorbital artery and vein, and the infraorbital nerve, a branch of the maxillary nerve.
It then emerges on the face through the infraorbital foramen and terminates by dividing into palpebral, lateral nasal and labial branches.

Infraorbital canal

orbital canal
Forming the exterior end of the infraorbital canal, the infraorbital foramen communicates with the infraorbital groove, the canal's opening on the interior side.
It is continuous with the infraorbital groove and opens onto the maxilla at the infraorbital foramen.

Infraorbital groove

Sulcus infraorbitalis
Forming the exterior end of the infraorbital canal, the infraorbital foramen communicates with the infraorbital groove, the canal's opening on the interior side.
Also not to be confused with the infraorbital canal, into which the groove enters, nor the infraorbital foramen, which is the canal's opening on the other side.

Skull

In human anatomy, the infraorbital foramen is an opening in the maxillary bone of the skull located below the infraorbital margin of the orbit.

Infraorbital margin

In human anatomy, the infraorbital foramen is an opening in the maxillary bone of the skull located below the infraorbital margin of the orbit.

Trigeminal nerve

The ramifications of the three principal branches of the trigeminal nerve—at the supraorbital, infraorbital, and mental foramen—are distributed on a vertical line (in anterior view) passing through the middle of the pupil.

Supraorbital foramen

Mental foramen

Woodland jumping mouse

woodland jumping
Representatives of the family Dipodidae are found in the northern regions of the Old and New Worlds, and are characterized by very large infraorbital foramen, and, in one of the two North American genera, Zapus, by four upper cheek teeth.

Zygomatic plate

Squirrels (family Sciuridae) tend to have broad zygomatic plate that extend above the infraorbital foramen.

Wabulacinus ridei

W. ridei is known from a right maxillary fragment (QMF 16851) containing molars one and two to the anterior section of the infraorbital foramen that was dorsal to the third molar.

Hystricognathi

The masseter medialis (a jaw muscle) passes partially through the infraorbital foramen and connects to the bone on the opposite side.

Crested porcupine

The skull is specific in many ways; first, the infraorbital foramen is greatly enlarged so portions of the masseter extend through it and attach from the frontal side surface of the snout.

Anterior superior alveolar nerve

The anterior superior alveolar branch (anterior superior dental branch), of considerable size, is given off from the maxillary nerve (the second branch of the trigeminal nerve or cranial nerve V, abbreviated V 2 ) just before its exit from the infraorbital foramen; it descends in a canal in the anterior wall of the maxillary sinus, and divides into branches which supply the incisor and canine teeth.

Asiatic lion

About half of Asiatic lions' skulls from the Gir forest have divided infraorbital foramina, whereas African lions have only one foramen on either side.

Eumuroida

nonburrowing formsother Muroidea
Norris et al. (2004) noted that two characters can be used to define the Eumuroida: the infraorbital foramen is V-shaped and extends to the roof of the palate, and the incisive foramina are medium to large in size.

Squalius malacitanus

S. malacitanus differs from its cogenerate species by having 7–8 branched rays in its dorsal fin, 8 branched rays in the anal lateral line; the number of scale rows above its lateral line; possessing 3 scale rows below its lateral line; 38 vertebrae, 21 abdominal, and 17 caudal; large fourth and fifth infraorbital bones; maxilla without a pointed anterior process; the middle of its frontal bone being narrow, as well as its neurocranium bone; the lower branch of its pharyngeal bone is rather long; and the shortness of the inferior lamina of its urohyal bone.
