Cisternen Flashcards
(18 cards)
What is the location of the Cisterna magna?
Between cerebellum and dorsal medulla
Also known as the cerebellomedullary cistern.
What are the main contents of the Cisterna magna?
- CSF
- Vertebral arteries
- Posterior inferior cerebellar artery (PICA)
- Cranial nerves IX, X, XI
CSF stands for cerebrospinal fluid.
Where is the Pontine cistern located?
Anterior to the pons
Also referred to as the prepontine cistern.
What are the main contents of the Pontine cistern?
- Basilar artery
- Abducens nerve (VI)
- Pontine perforators
The abducens nerve is involved in eye movement.
What is the Interpeduncular cistern’s location?
Between cerebral peduncles (midbrain)
This cistern is crucial for various neural connections.
What does the Interpeduncular cistern contain?
- Oculomotor nerves (III)
- Basilar bifurcation
- Posterior cerebral arteries (PCA)
- Superior cerebellar arteries (SCA)
The oculomotor nerve is responsible for eye movement and pupil response.
Where is the Ambient cistern located?
Lateral to the midbrain (connecting interpeduncular & quadrigeminal)
This cistern plays a role in cerebrospinal fluid circulation.
What are the main contents of the Ambient cistern?
- Trochlear nerve (IV)
- PCA
- SCA
- Basal vein of Rosenthal
The trochlear nerve is also involved in eye movement.
What is the location of the Quadrigeminal cistern?
Posterior to the midbrain tectum (colliculi)
Also known as the superior cistern.
What are the main contents of the Quadrigeminal cistern?
- Great cerebral vein (of Galen)
- Pineal gland
- PCA branches
- SCA branches
The great cerebral vein drains blood from the brain.
Where is the Chiasmatic cistern located?
Around optic chiasm
The optic chiasm is where the optic nerves cross.
What are the main contents of the Chiasmatic cistern?
- Optic nerves and chiasm
- Anterior cerebral arteries (ACA)
- Anterior communicating artery
The anterior communicating artery connects the left and right anterior cerebral arteries.
What is the Suprasellar cistern’s location?
Above sella turcica, near pituitary
The sella turcica is a bony structure at the base of the skull.
What are the main contents of the Suprasellar cistern?
- Optic chiasm
- Pituitary stalk
- Circle of Willis (ACA, ICA, PCA)
The Circle of Willis is a critical arterial structure supplying blood to the brain.
Where is the Cisterna lamina terminalis located?
Anterior to third ventricle, near lamina terminalis
This cistern is associated with important vascular structures.
What does the Cisterna lamina terminalis contain?
- Anterior communicating artery
- ACA segments
The anterior communicating artery is key in cerebral circulation.
What is the location of the Cistern of the lateral cerebral fossa?
Within the lateral sulcus
Also known as the Sylvian cistern.
What are the main contents of the Cistern of the lateral cerebral fossa?
- Middle cerebral artery (MCA)
- Superficial middle cerebral vein
The MCA supplies a large portion of the lateral aspect of the cerebral hemisphere.
