- Cerebrospinal Fluid
- The ventricles
- The meninges
Answer: The meninges
- What separates the motor and sensory strips?
- The Sagittal Fissure
- The Sylvian Fissure
- The Central Sulcus

3. The interconnecting blood vessels at the base of the brain make up:
- The Circle of Milford
- The Circle of Willis
- The Carotid Exchange
- The Blood Circle
Answer: The Circle of Willis
4. The Artery of Adamkiewicz is:
- A major feeder vessel to the spinal cord
- A major branch of the Iliac Arteries
- A major feeding vessel to the kidneys
- A major blood vessel supplying the brain
Answer: A major feeder vessel to the spinal cord
5. The C8 nerve root exits the spinal cord:
- Above the T1 vertebrae
- Above the C8 vertebrae
- Below the C8 vertebrae
- There is no C8 nerve root: Remember, nerve roots C1-7 exit above there respective 1 / 4
vertebrae. Between C7 and T1 exits C8, so all nerve roots below C8 exit below their respective vertebrae.
Answer: Above the T1 vertebrae
6. The nerve roots that extend below the spinal cord make up the:
- Conus Medularis
- Cauda Equina
- Filum Terminale
- Spina Bifida
Answer: Cauda Equina
- The Tibial and Common Peroneal nerves form from what nerve?
- Femoral
- Saphenous
- Sural
- Sciatic
Answer: Sciatic
8. Stimulation of the Peroneal nerve is perfomed:
- Across the head of the Fibula
- Across the Medial Malleolus
- Across the Lateral Malleolus
- In the medial third of the antecubital space
Answer: Across the head of the Fibula
9. Lower motor neurons primarily exit the spinal cord through:
- The dorsal columns
- The dorsal nerve roots
- The dorsal root ganglia
- The ventral nerve roots
Answer: The ventral nerve roots
- What main descending tract in spinal cord is monitored by Motor Evoked Potentials?
- Rubrospinal
- Corticospinal 2 / 4
- Tectospinal
- Corticobulbar
Answer: Corticospinal
- What anatomical area is associated with the "motor strip"?

d. somatosensory cortex, grey matter: motor cortex, ventral horn
- Muscles providing gross motor control, such as the gastrocnemius, tend to be easy to
obtain when running TcMEP because....
- The motor unit has a large ratio of neuron to muscle fibers
- The devotion of the homunculus to those muscles
