The cell bodies of first order sensory neurons are found here
DRG
This is the major descending pathway controlling voluntary movement of the limbs
Lateral corticospinal tract
This type of cerebral oedema results from disruption of the BBB
Vasogenic oedema
The 3 major cerebral arteries supplying the cerebral hemispheres are these
ACA, MCA, PCA
This cranial nerve provides the afferent limb of the corneal reflex, while this cranial nerve provides the efferent limb
CNV1 and CNVII
Fibers of the corticospinal tract, corticobulbar tract, and many sensory pathways all pass through this white matter structure
Internal capsule
This type of TBI has a “lens” shape on CT and typically arises from laceration to the middle meningeal artery
Epidural/Extradural haematoma
This artery supplies the lateral pons where cranial nerves VII and VIII are located
AICA
A patient has tongue deviation toward the left when protruding the tongue but no weakness of facial expression. Name the affected cranial nerve AND what brainstem subdivision it arises from
CNXII, Medulla
This part of the basal ganglia excites the GPi in the indirect pathway, increasing inhibition of the thalamus
Subthalamic nucleus (STN)
In the pathway of cytotoxic oedema, the influx of ions into the presynaptic neuron causes excessive release of this neurotransmitter, which in turn releases an excess of what ion?
Glutamate and calcium
A patient has contralateral leg weakness with relatively spared arm and face strength. This artery is most likely occluded.
ACA
A patient suffers a fracture of the T10 vertebrae and examination shows weakness of the left leg, loss of vibration and proprioception on the left below T10 and loss of pain and temperature sensation on the right side. What part of the spinal cord is affected?
Left half (Brown Sequard Syndrome)
A patient has an intention tremor, dysmetria, and impaired heel-to-shin testing on the right side after suffering a stroke. What part of the brain is affected (including side affected)
Right cerebellar hemisphere
A patient develops ascending weakness and areflexia one week after a viral infection. This immune-mediated neurological disorder is the most likely diagnosis
Guillain-barre syndrome (acute inflammatory demyelinating polyneuropathy)
A patient presents with ptosis, a dilated pupil, and a "down-and-out" eye caused by compression from an aneurysm of this artery
Posterior communicating artery (PCom)
