What is the classification of the temporal bone?
By Isabella Harris
What is the classification of the temporal bone?
Each temporal bone fracture was classified according to the traditional (longitudinal, transverse, or oblique) and new (otic capsule sparing or otic capsule involving) classification schemes. Longitudinal fractures were defined as fractures running parallel to the petrous pyramid.
What are features of the temporal bone?
They are highly irregular bones with extensive muscular attachments and articulations with surrounding bones. There are a number of openings and canals in the temporal bone through which structures enter and exit the cranial cavity. The temporal bone also houses the structures forming the middle and inner ear.
What structures are found in the temporal bone?
The temporal bone consists of four parts— the squamous, mastoid, petrous and tympanic parts….Borders
- Occipitomastoid suture.
- Squamosal suture.
- Sphenosquamosal suture.
- Zygomaticotemporal suture.
What bones does the temporal bone articulate with?
The temporal bone articulates anteriorly with the sphenoid bone, above with the parietal bone, and posteriorly with the occipital bone. The zygomatic process of the squamosal part has an anterior and a posterior root between which, on the lower surface, is located the mandibular canal.
What are the boundaries of the temporal fossa?
Summary
- Superiorly and posteriorly – superior temporal line.
- Inferiorly – zygomatic arch.
- Anteriorly – frontal process of the zygoma and zygomatic process of the frontal bone.
Which portion of the temporal bone houses the structures of the internal ear quizlet?
Terms in this set (35) supra-orbital margin. Which portion of the temporal bone houses the structures of the internal ear? sinuses.
How many bones does the temporal bone articulate with?
The temporal bones are divided into the squamosal, mastoid, tympanic, styloid, and petrous segments. Each articulates with the zygomatic bone (zygomaticotemporal suture), sphenoid bone (sphenosquamosal suture), parietal bone (parietosquamous suture), and occipital bone (occipitomastoid suture).
Which portion of the temporal bone houses the structures of the internal ear?
The correct answer is (B): petrous. The petrous area of the temporal bone forms part of the cranial base. The middle and inner ear structures are…
Which bones does the temporal bone articulate with?
What foramina are present in the temporal bone?
Skull
| Bone | Cranial fossa | Foramina |
|---|---|---|
| temporal | middle cranial fossa | carotid canal |
| temporal | posterior cranial fossa | internal acoustic meatus |
| temporal | posterior cranial fossa | jugular foramen |
| temporal | posterior cranial fossa | stylomastoid foramen |
What structure is superior wall of temporal fossa?
The temporal fossa is bounded by a few anatomical landmarks, anteriorly the frontal process of the zygomatic bone, superiorly and posteriorly the temporal lines, and inferiorly the zygomatic arch.
