The right and left maxillae are the principal bones of the
facial skeleton
the orbital floor
the lateral wall of the
nasal cavity
the greater anterior part of the
hard palate
the lower margin of the nasal aperture
the intermaxillary suture
The body
The frontal processes
The Zygomatic processes
The alveolar processes
The palatine processes
The maxillary air sinus
a large pyramid-shaped cavity lined with mucous
membrane
The anterior surface
the facial skeleton below the infra-orbital margin
the infra-orbital foramen
The medial edge of the anterior surface formed the
lateral and inferior boundary of the anterior nasal
cavity.
The orbital surface
the medial part of the floor of the orbit
laterally with the zygomatic bone
medially with the orbital plate of the ethmoid bone and the
lacrimal bone
the infra-orbital groove and canal
The infratemporal surface
the anterior wall of the pterygopalatine fossa medially and
the infratemporal fossa laterally.
one or more foramina for the
posterior superior vessels and
nerves to maxillary tubercle
The posterior surface
convex surface that contains foramen for transmits
superior alveolar nerve and blood vessel
The pterygomaxillary fissure
The nasal surface
the anterior part of the lateral wall of the nasal cavity
and has a rough a rough area behind for articulation
with the perpendicular plate of the palatine bone
The greater palatine canal
In front of the arc for the palatine bone there is a large opening,
which leads into the maxillary sinus
Above the opining the ethmoidal bulla and uncinate process
encroach on the upper part of the opening.
The nasolacrimal duct
The anterior boundary is continuous below with the conchal
crest for the anterior part of the inferior conchae.
Medially the nasolacrimal groove is closed in by processes of
the lacrimal bone and the inferior conchae.
The frontal process
a thin flattened projection, which extends upwards
and articulates with the frontal bone
laterally with the nasal bone
medially with the lacrimal and ethmoidal bones
The lateral edge forms the medial margin of the orbital
cavity
The posterior part of this process is hollowed out and this
together with the hollow on the lacrimal bone forms the
lacrimal groove.
The medial surface forms the upper anterior part of the
lateral wall of the nasal cavity.
The zygomatic process
projects laterally from the upper lateral part of the body
and articulates with the zygomatic bone.
The alveolar process
The canine eminence
The incisive fossa
The canine fossa
The palatal process
projects medially at the junction of the body with the
alveolar process and articulate by a suture with the
corresponding palatal process of the opposite side.
their posterior margins articulate with the horizontal
processes of the palatine bone.
Above, the median crest formed by the fusion of the two
palatal processes of the maxillae
behind with the vomer
in front with the septal cartilage
The incisive fossa
a small triangular depression in the hard palate behind the
central incisor teeth.
The fossa leads upwards into a canal in each palatine
process.
