Chapter 01: Orientation to the Structure and Imaging of the Central Nervous System Haines: Fundamental Neuroscience for Basic and Clinical Applications, 6th Edition Test Bank MULTIPLE CHOICE 1. A 66-year-old man presents with paralysis of the upper and lower extremities on the right and paralysis of most movement of the left eye. Which of the following represents the best “localizing sign” in this patient? a. Paralysis of the right upper extremity b. Paralysis of the right lower extremity c. Paralysis of upper and lower extremities d. Paralysis of most eye movements on the left e. Sensory deficits on the right side ANS: D Long tract signs, such as motor and sensory losses of the extremities, could indicate a lesion at many different levels of the neuraxis. However, these tracts pass through the midbrain. Significant deficits of eye movement in this patient indicate a lesion of the oculomotor nerve, the nucleus of which is located in the midbrain and the root of which exits the midbrain. In fact, the corticospinal tract is quite close to the root of the oculomotor nerve in anteromedial areas of the mesencephalon. 2. A patient presents to the emergency department with a sensory deficit involving the same side of the face and body. This would most likely suggest a lesion in which of the following structures? a. Cerebral hemisphere b. Brainstem c. Cervical spinal cord d. Lumbosacral spinal cord e. Peripheral nerve roots ANS: A In general, sensory and/or motor deficits located on the same side of the face and body signify damage to a cerebral hemisphere. Lesions of the brainstem usually result in alternating deficits or crossed deficits (face/head one side, body opposite side), whereas damage to the spinal cord will result in deficits of the body below the lesion, with sparing of the head and/or face. 3.
