Canal (anatomy)

canalcanaliscanals
The infraorbital canal is a canal found at the base of the orbit that opens on to the maxilla.
Infraorbital canal

Infraorbital groove

Sulcus infraorbitalis
It is continuous with the infraorbital groove and opens onto the maxilla at the infraorbital foramen.
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.

Orbit (anatomy)

orbitorbitseye socket
The infraorbital canal is a canal found at the base of the orbit that opens on to the maxilla. One of the canals of the orbital surface of the maxilla, the infraorbital canal, opens just below the margin of the orbit, the area of the skull containing the eye and related structures.
The bony walls of the orbital canal in humans do not derive from a single bone, but a mosaic of seven embryologically distinct structures: the zygomatic bone laterally, the sphenoid bone, with its lesser wing forming the optic canal and its greater wing forming the lateral posterior portion of the bony orbital process, the maxillary bone inferiorly and medially which, along with the lacrimal and ethmoid bones, forms the medial wall of the orbital canal.

Infraorbital nerve

infra-orbital nerveinfraorbital portion
The infraorbital nerve and infraorbital artery travel through the canal.
After the maxillary nerve enters the infraorbital canal, the nerve is frequently called the infraorbital nerve.

Infraorbital foramen

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

Maxilla

The infraorbital canal is a canal found at the base of the orbit that opens on to the maxilla. One of the canals of the orbital surface of the maxilla, the infraorbital canal, opens just below the margin of the orbit, the area of the skull containing the eye and related structures.

Infraorbital artery

Anterior superior alveolar nerve

Before exiting, the anterior superior alveolar nerve, middle superior alveolar nerve and corresponding arteries will branch off.

Sciuromorpha

Traditionally, the term has been defined on the basis of the shape of the infraorbital canal.

Geomyoidea

Geomyoids are most noticeably characterized by the position of the infraorbital canal.

Maxillary sinus

The infraorbital canal usually projects into the cavity as a well-marked ridge extending from the roof to the anterior wall; additional ridges are sometimes seen in the posterior wall of the cavity and are caused by the alveolar canals.

Panthera blytheae

However, current evidence shows that the species has a number of features common in other Panthera species, including a "frontoparietal suture located at the postorbital constriction", and an "absence of an anterior bulge overhanging the infraorbital canal".

Platacanthomyidae

Oriental dormice
They can be distinguished from both the family Spalacidae and the Eumuroida (all non-spalacid and non-platacanthomyid muroids), by the distinct shape of their infraorbital canal and by the presence of multiple openings in the palate of the skull.

Magnuviator

On the underside of the jaw, the palatine bone uniquely bears an opening near the front end that extends forward into the skull to connect to the infraorbital canal.

Sciurognathi

Alternatively, some texts group rodents into three suborders on the basis of the shape of the infraorbital canal.

Infraorbital vein

vein
Accompanied by the infraorbital artery and the infraorbital nerve, it passes posteriorly through the infraorbital foramen, infraorbital canal, and infraorbital groove.

Diatomys

The infraorbital canal is enlarged, presumably allowing for the passage of the medial masseter muscle as with other hystricomorphs.

Respiratory system of the horse

breathingEquine respiratory systemnormal anatomy
Maxillary sinuses: Within the maxilla, above the tooth roots. Each is divided into two components, the Rostral maxillary sinus in front and the Caudal maxillary sinus behind. They do not communicate. In addition, each of these is subdivided into a medial (inside) and lateral (outside) component, by an incomplete bone wall that carries the infraorbital canal containing nerves and blood vessels. The close proximity to the tooth roots mean that as the teeth erupt with age, the maxillary sinuses become larger.
