Neuroanatomy Flashcards
What part of the brain lies in the anterior cranial fossa
Frontal lobe
Which part of the brain lies in the middle cranial fossa
Temporal lobe
Which part of the brain lies in the posterior cranial fossa
Cerebellum
What part of the brain lies above the sphenoid bone
Hypothalamus
Which part passes through foramen magnum
Medulla
What happens if CSF circulation is blocked by a tumour
Expansion of ventricles causing hydrocephalus
Where is CSF in ventricular system made
Choroid plexus
Which part of the ventricular system relates to cerebral hemisphere
Lateral ventricle
Which part of the ventricular system relates to the diencephalon
Third ventricle
What part of the ventricular system relates to the midbrain
Cerebral aqueduct
Which part of the ventricular system relates to the pons and medulla
Fourth ventricle
Why can the circle of Willis maintain perfusion of the brain even if there is blockage in one part of the structure
The structure is a circular connection of blood vessels so the blood coming up from one of the arteries can flow in either direction around the circle and avoid any blockage or narrowing of blood vessels
What artery supplies the primary motor cortex for the face
Middle cerebral artery
What artery supplies the primary cortex for the arm
Middle cerebral artery
What artery supplies the primary motor cortex for the foot and leg
Anterior cerebral artery
