CA III Midterm

Question 1

recording of electrical activity in the brain, whose cells emit distinct patterns of rhythmic electrical impulses

Answer 1

electroencephalography (EEG)

Question 2

recording of electrical signals (action potentials) that occur in a muscle when it is at rest and during contraction to assess nerve damage

Answer 2

electromyography (EMG)

Question 3

needle puncture of the spinal cavity to extract spinal fluid for diagnostic purposes, introduce anesthetic agents into the spinal canal, or remove fluid to allow other fluids to be injected; aka spinal puncture or spinal tap

Answer 3

lumbar puncture

Question 4

test that measures the speed at which impulses travel throughout a nerve

Answer 4

nerve conduction velocity (NCV)

Question 5

series of chemical, microscopic, and microbial tests used to diagnose disorders of the CNS. including viral and bacterial infections, tumors, and hemorrhage

Answer 5

cerebrospinal fluid (CSF) analysis

Question 6

radiography of the blood vessels after introduction of a contrast medium

Answer 6

angiography

Question 7

radiography of the blood vessels of the brain after injection of a contrast medium

Answer 7

cerebral angiography

Question 8

imaging technique achieved by rotating an x-ray emitter around the area to be scanned and measuring the intensity of the transmitted rays from different angles

Answer 8

computed tomography (CT)

Question 9

diagnostic radiological examination of the spinal canal, nerve roots, and spinal cord after injection of a contrast medium into the spinal canal

Answer 9

myelography

Question 10

scan using CT to record the positrons emitted from a radiopharmaceutical and produce a cross-sectional image of metabolic activity in body tissues to determine the presence of a disease

Answer 10

positron emission tomography (PET)

Question 11

imaging procedure using high frequency sound waves that display the reflected echoes on a monitor

Answer 11

ultrasound (US)

Question 12

US technique used to study intracranial structures of the brain and conditions that cause a shift in the midline structures of the brain

Answer 12

echoencephalography

Question 13

technique that exposes abnormal tissue to extreme cold to destroy it

Answer 13

cryosurgery

Question 14

precise method of locating and destroying sharply circumscribed lesions on specific, tiny areas of pathological tissue in deep-seated structures of the CNS

Answer 14

stereotaxic radiosurgery

Question 15

partial destruction of the thalamus to treat intractable pain, involuntary movements, or emotional disturbances

Answer 15

thalamotomy

Question 16

transection of a nerve tract in the brainstem or spinal cord

Answer 16

tractotomy

Question 17

technique that cuts a circular opening into the skull to reveal brian tissue and decrease intracranial pressure

Answer 17

trephination
