The skull is formed by the __________ and _________ bones. | cranium, facial |
How many cranial bones are there? | 8 |
What are the cranial bones? | 2 parietal, 2 temporal, frontal, occipital, sphenoid, ethmoid |
The articulation between the parietal bones and frontal bone anteriorly is the: | coronal suture |
Where right and left parietal bones meet superiorly is the: | sagittal suture |
Where parietal bones meet the occipital bone posteriorly is the: | lambdoid suture |
Where parietal and temporal bones meet is the: | squamosal or squamous suture |
What are the four major regions of the temporal bones? | Squamous, Tympanic, Mastoid, Petrous |
The _________ bones form most of the superior and lateral aspects of the skull. | parietal |
The _________ bones form the inferiolateral aspects of the skull and parts of the cranial floor. | temporal |
The _________ bone forms most of the skull's posterior wall and base. | occipital |
The _________ bone is a butterfly shaped bone that spans the width of the middle cranial fossa and articulates with all other cranial bones. | sphenoid |
The _________ bone forms the anterior portion of the cranium. | frontal |
The _________ bone forms most of the bony area between the nasal cavity and the orbits. | ethmoid |
The _________ bones are tiny irregularly shaped bones that appear within sutures. AKA sutural bones. | wormian |
There are ____ facial bones. | 14 |
Only the ______ and ______ are unpaired facial bones. | mandible, vomer |
The _______ is the largest, strongest bone of the face. | mandible |
The names of the paired facial bones are: | maxillae, zygomatics, nasals, lacrimals, palatines, inferior conchae |
The _________ bones are irregularly shaped bones that form the prominences of the cheeks and the inferolateral margins of the orbits. | zygomatic |
The ________ is a plow-shaped bone that forms part of the nasal septum. | vomer |
The _______ bones are thin medially fused bones that from the bridge of the nose. | nasal |
The _______ bones contribute to the medial walls of the orbit and contain a deep groove called the _______ fossa that houses the ________ sac. | lacrimal |
The _______ bones are two bone plates that form portions of the hard palate, the posterolateral walls of the nasal cavity, and a small part of the orbits. | palatine |
The _______ _______ _______ are paired, curved bones in the nasal cavity that form part of the lateral walls of the nasal cavity. | inferior nasal conchae |
