Skeletal Flashcards
3 portions of Temporal
- Squamous
- Tympanic
- Petrous
of bones in Skull

Vomler
Forms inferior portion of nasal septum w/ perpendicular plate of ethmoid bone
TMJ articulates at:
Squamous part of Temporal bone
Zygomatic Arch
zygomatic process of temporal (squamous) + temporal process of zygomatic bone
Sphenoid Foramen
- Ovale (mand. nerve)
- Spinosum (meningeal)
- Rotundum (max. nerve)
- Lacerum (internal carotid)
Ethmoid Bone
Also helps connect cranium to facial.

Temporal: Squamous Portion
TMJ :
Articular fossa
Articular eminence
Postglenoid fossa
Temporal: Typanic Portion
External acoustic meatus Petrotypanic fissure (separates petrous portion)
Temporal: Petrous Portion
Mastoid process Styloid process Stylomastoid foramen Internal acoustic meatus Carotid canal
Sphenoid Bone
[Butterfly]
Helps connects cranial skeleton to facial skeleton tissue
Christa galli
Ethmoid
Vertical midline continuation of perpendicular plate -. Meninges brain attachment
Cribiform plate
Ethmoid
Horizontal - allows for passage of olfactory nerves
Nasolacrimal duct
Lacrimal + Maxilla
Skull Fossae
Temporal - whole temporal bone,
Infratemporal - contains pterygoid muscle
Pterygopalatine - come shaped, deep
muscles, blood vessels and nerves
