What is the function of the maxillary bone?
The maxilla has several main functions, including: holding the top teeth in place. making the skull less heavy. increasing the volume and depth of your voice.
What is the role 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 does infraorbital mean?
: situated beneath the orbit the infraorbital prominence of the cheekbones.
What is the infraorbital sulcus and what does it become?
infraorbital groove The groove on the orbital surface of the maxilla that runs forward to become the infraorbital canal. The infraorbital nerve runs in the groove and canal to exit through the infraorbital foramen on the front of the skull just below the orbit.
What are features of the maxillary bone?
Each maxillary bone has the shape of a pyramid, it’s base adjacent to the nasal cavity, its apex being the zygomatic process, and its body constituting the maxillary sinus. [3] The maxilla connects with surrounding facial structures through four processes: alveolar, frontal, zygomatic and palatine.
What is the maxillary?
Maxillae are a pair of bones that form the dominant portion of the face. Functionally, the maxillae hold the tooth roots and form most of the nasal aperture and floor, most of the hard palate, and the floors of the orbits.
What passes through infraorbital foramen of maxilla?
skeletal structure of face 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.
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 is infraorbital?
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. The canal may reside entirely in the maxillary sinus, suspended from the sinus roof by a mesentery.
Where is the infraorbital region?
The infraorbital region is a component of the midface and can be defined as the anatomical area between the nasal aperture and the zygomatic bone below the inferior rim of the orbit and above the roots of the maxillary canine and premolars (Fig.
What does the maxillary nerve supply?
In sum, the maxillary nerve innervates the skin of the lower eyelid, the prominence of the cheek, the alar part of the nose, part of the temple, and the upper lip (Figures 2.2 and 2.3).
Where does maxillary nerve enter orbit?
inferior orbital fissure
It innervates skin on the cheek prominence. 3) The floor of the orbit: After exiting the pterygopalatine fossa through the inferior orbital fissure, the maxillary nerve enters the orbit as infraorbital nerve which is its terminal branch.
Where is the infraorbital foramen located in the 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. It transmits the infraorbital artery and vein, and the infraorbital nerve, a branch of the maxillary nerve.
What is the function of the maxilla bone?
The function of the maxilla is to provide protection of the face, support of the orbits, hold the top half of the teeth in place, and form the floor of the nose.
Where does the intermaxillary suture of the maxilla form?
The maxillary bones on each side join in the middle at the intermaxillary suture, a fused line that is created by the union of the right and left ‘halves’ of the maxilla bone, thus running down the middle of the upper jaw.
Is the maxilla part of the orbital fissure?
The maxilla, along with several other bones, forms the borders of the inferior orbital fissure in the floor of the orbit (Figure 1). This fissure transmits several vessels and nerves, including the maxillary nerve (a branch of cranial nerve 5 or trigeminal nerve) or its continuation, the infraorbital nerve.
