Neuroanatomy Flashcards
The anterior cerebral artery perfuses which section of the brain?
Medial aspect of the
- frontal lobe
- anterior portion of the parietal lobe.
Regions of the brain supplied by the anterior cerebral arteries
Medial aspects of the frontal lobe and anterior parietal lobe
Regions of the brain supplied by the middle cerebral arteries
Cortex of lateral frontal lobe, some parietal lobe and temporal lobe.
Regions of the brain supplied by the posterior cerebral arteries
Inferior and medial temporal and occipital lobes
Superior sagittal sinus
- Location
- Drainage
- Runs along the falx cerebri
- Drains into transverse sinuses bilaterally
Superior sagittal sinus
- Location
- Drainage
- Runs along the superior edge falx cerebri
- Drains into transverse sinuses bilaterally
Inferior sagittal sinus
- location
- drainage
Located along the inferior edge of the falx cerebri
Drains into straight vein, receiving a connection from the great cerebral vein (Vein of Galen)
Inferior sagittal sinus
- location
- drainage
Located along the inferior edge of the falx cerebri
Drains into straight vein, receiving a connection from the great cerebral vein (Vein of Galen)
- Forms confluence of sinuses before draining into transverse sinuses
Cavernous sinus receives blood from?
Superficial middle cerebral vein
Ophthalmic arteries (superior and inferior)
Cavernous sinus drainage
From the superior and inferior petrosal veins.
Superior drains into the transverse sinus.
Inferior drains into the internal jugular vein
Structures that pass through the lateral wall of the cavernous sinus.
Superior-to-inferior:
- Oculomotor nerve (CN3)
- Trochlear nerve (CN4)
- Ophthalmic nerve (CN5)
- Maxillary nerve (CN55)
Structures that pass through the medial wall of the cavernous sinus?
Abducens nerve (CN6)
Internal carotid artery
