1. cerebellum A 60-year old patient displays ataxic stance and gait, as well as loss of motor
coordination due to a vascular lesion in the central nervous system. Where is this
lesion likely to be located?
2. caudal Where is the occipital lobe located with respect to the parietal?
3. frontal A 41-year old male presents to the ER with paralysis involving the left arm and
hand. Imaging shows a small lesion in his cerebral cortex. The lesion is located in
what lobe of the brain?
4. corpus callosum A sagittal MRI of your brain is located at, or immediately adjacent to, the midline.
Which of the following spaces or structures would characterize this particular
plane of section in the MRI of your brain?
5. nuclei Collections of nerve cell bodies inside the CNS are called:
6. frontal The MRI of a 27 year old woman shows a meningioma impinging on the gyrus
rectus in axial and coronal MRI. This most likely represents an olfactory groove
meningioma. This lesion is impinging which of the following lobes of the cerebral
hemisphere?
7. occipital lobe Which is the primary area for receiving visual impulses?
8. cauda equina The collections of anterior and posterior nerve roots that occupy the lumbar
cistern are collectively known as which of the following?
9. filtration of blood Formation of cerebrospinal fluid involves:
through choroid
endothelial cells
10. subarachnoid he- Red blood cells present in CSF could be indicative of:
morrhage
11. Which structure connects the lateral ventricle to the third ventricle?

intraventricular
foramina of
Monro
12. lateral foramina Cerebrospinal fluid (CSF) enters the subarachnoid space via which of the following
of Luschka structures?
13. aqueduct of In a patient with non-communicating hydrocephalus, a tracer dye was injected
Sylvius into the right lateral ventricle and the dye was not detected in the lumbar CSF. A
CT scan showed dilation of both cerebral ventricles and 3rd ventricles, but not in
the 4th ventricle. Based on this information in this patient, obstruction of CSF flow
may be at which of the following locations in the brain?
14. non-communi- This CT belongs to a 2-year-old girl with ependymoma (tumor) in the 4th ventricle.
cating What type of hydrocephalus will be diagnosed?
15. arachnoid granu- A 13 year-old girl with recent onset of headaches, nausea, and cognitive difficulties
lations is diagnosed with communicating (non-obstructive) hydrocephalus. The most
likely location to cause this condition is:
16. pineal gland Circumventricular organs are highly vascularized structures that are permeable
to various substances in the blood. An example of a secretory circumventricular
organ is the:
17. dendrite The principal region of the neuron for receiving information is the:
18. Perikaryon What is the cell body of a neuron called?
19. motor neuron Which type of neurons transmit impulses through PNS to ganglia or effector cell?
20. 99.9% What percentage of neurons in the body are interneurons?
