Which bone has the infraorbital foramen?
Which bone has the infraorbital foramen?
maxillary bone
The infraorbital foramen is located in the maxillary bone. It is the anterior opening of the infraorbital canal, which is the anterior continuation of the infraorbital groove, which course through the floor of the orbit.
Where can I find infraorbital foramen?
The infra-orbital foramen is located above the zygomatic process of the maxilla, about 2–3 cm from the median vertical line of the face. This orifice is more important than the supra-orbital foramen (Fig. 16.6).
Which artery reaches the face through the infraorbital foramen?
the maxillary artery
Infraorbital artery (IOA) is the branch of the maxillary artery. It appears in pterygopalatone fossa as a branch of third part of maxillary artery. It enters the orbit through inferior orbital fissure traveling anteriorly through infraorbital groove and infraorbital canal.
What is the functions of infraorbital foramen?
The infraorbital foramen are a pair of external foramina of the skull which are visible anteriorly on the skull. Foramen (foramina is plural), are holes in the human body which allow other structures to pass through. In the case of the skull, foramina permit the passage of arteries, veins and nerves.
What nerve exits the infraorbital foramen?
maxillary nerve
The infraorbital nerve is a branch of the maxillary nerve, itself a branch of the trigeminal nerve (CN V). It travels through the orbit and enters the infraorbital canal to exit onto the face through the infraorbital foramen….

What is the purpose of infraorbital foramen?
In human anatomy, the infraorbital foramen is an opening in the maxillary bone of the skull located below the infraorbital margin of the orbit. It transmits the infraorbital artery and vein, and the infraorbital nerve, a branch of the maxillary nerve.
What bone is the maxilla?
upper jaw
The maxilla is the bone that forms your upper jaw. The right and left halves of the maxilla are irregularly shaped bones that fuse together in the middle of the skull, below the nose, in an area known as the intermaxillary suture. The maxilla is a major bone of the face.
Where is the infraorbital artery located and where does it supply blood to?
It supplies the lower eyelid and lacrimal sac, and it anastomoses with the angular artery and the dorsonasal artery. While in the infraorbital canal, the infraorbital artery supplies the inferior rectus and inferior oblique muscles and sends some branches to the maxillary sinus and to the teeth of the upper jaw.
What is infraorbital foramen?
The infraorbital foramen, an opening into the floor of the eye socket, is the forward end of a canal through which passes the infraorbital branch of the maxillary nerve, the second division of the fifth cranial nerve.
