Maxillary Bone Flashcards
1. Identify features of the maxilla including the zygomatic process, frontal process, orbital border, maxillary sinus, and inter-maxillary suture 2. Identify the infaorbital foramen and infraorbital groove 3. Identify with how many bones each maxilla articulates
Oddly-shaped bone that is fused at the midline via the inter maxillary suture
Maxilla
This process of the maxilla is the upward projection portion between the nasal and lacrimal bones. It articulated with the frontal bone
Frontal Process of Maxilla
This plate is the anterior part of the maxilla where it helps form part of the floor of the orbit
Orbital Plate of Maxilla
This foramen is important because of a branch of the maxillary division of CN V exits the maxilla to provide sensory innervation to the cheek.
Infraorbital Foramen
located right below the eye
This suture connects the 2 sides of the maxilla
Intermaxillary suture
From an inferior view, the maxilla articulates with these 2 bones
Zygomatic and palatine bones
From sagittal view of the skull, the maxilla articulates with these 3 bones to form part of the nasal cavity
Inferior Nasal Concha
Vomer
Ethmoid
This sinus is a hollow space within the maxillary bone located above the teeth and below the cheekbones
Maxillary sinus
Largest paranasal sinus lined with mucus, which drains into the nasal cavity
Maxillary sinus
This sinus can cause a spread of infection to the orbit because it lies near
Maxillary sinus
Has a groove (infraorbital groove) where a branch of the maxillary nerve (V2 of CN V) runs into the floor of the orbit
Orbital Process of the Maxilla
This nerve runs behind the inferior orbital rim and comes out onto the face via infraorbital foramen
V2 of CN V
T/F: The maxilla articulates with bones of the Viscero and Neurocranium
