What is the significance of the Pterion?
|
fusion of 4 cranial bones and is easily fx. Ant. br. of Middle Meningeal A. runs through here so can be damaged. What is this area of fusion called?
|
|
|
What bones make up the Asterion?
|
Fusion site of these bones is called what: Occiptal, temporal, parietal?
|
|
|
Identify the layers and spaces of the Meninges (sup. to deep).
|
Epidural space (potential)
Dura: periosteal layer, Dural Venous Sinuses, meningeal layer Subdural Space (potential) Arachnoid Subarachnoid space (real- CSF) Pia Brain Intercerebral Space |
|
|
Name the Midline dural sinuses and describe where they are. Locate them on netter 103/104.
|
*these all create groove in cranial fossa
Superior Sagittal Sinus- begins in crista galli and ends near internal occipital protuberance at confluence Straight Sinus- runs inferoposteriorly along line of attachment of cerebral falx to tentorium cerebelli where it joins confluence Inferior Sagittal Sinus: runs in inferior concave free border of the falx cerebelli and ends in the straight sinus Occipital Sinus- lies in attached border of falx cerebri and ends superiorly in confluence Confluence of Sinuses- where sup. sagittal, straight, occipital, and transverse sinuses meet in post. cranium. |
|
|
Name the Paired dural sinuses and locate them on netter 103/104.
|
Transverse Sinus
Sigmoid sinus--> int. jugular V. Cavernous Sinus Sup. Petrosal sinus--> beginning of sigmoid sinus Inferior Petrosal sinus--> end of sigmoid sinus Sphenoparietal sinus Intercavernous sinus (ant/post) |
|
|
What structures are in the cavernous sinus?
|
Internal Carotid A.
CN III (Occulomotor N.) CN IV (Trochlear N.) CN V1 (Opthalmic N.) CN V2 (Maxillary N.) CN VI (Abducens N.) |
|
|
What is the order of flow in the sinuses?
|
Confluence-->
Transverse--> Sigmoid--> Jugular V |
|
