Medical Terminology 6, 7 & 8

Front 1

Bone scan

Back 1

Involves the intravenous injection of a radioscope, which is absorbed by the bone tissue. After 3 hours the skeleton is scanned with a gamma camera moving from one end of the body to the other. Detects the area of the radioactive concentration and converst the radioactive image to a screen where the concentrations show up as a pinpoint dots cast in the image of a skeleton.

Front 2

Bone density evaluation

Back 2

Process of removing a small sample of bone marrow from a selected site with a needle for the purpose of examining the specimen under a telescope.

Front 3

dual photon absorptiometry

Back 3

Noninvasive procedure that involves beaming a minimal amount of radiation through the bones. A computer then evaluates the amount of radiation absorbed by the bones and summarizes the findings, which are then interpreted by the physician.

Front 4

dual energy x-ray absorptiometry (DEXA)

Back 4

Noninvasive procedure that measures bone density. An x-ray machine generates the energy protons that pass through the bones.

Front 5

muscle biopsy

Back 5

Extractions of the specimen of muscle tissue, through either a biopsy needle or an incisional biopsy, for the purpose of examining it under a microscope.

Front 6

electromyography

Back 6

Process of recording the strength of the contraction of a muscle when it is stimulated by an electric current.

Front 7

arthrocentesis

Back 7

Surgical puncture of a joing with a needle for the purpose of withdrawing fluid for analysis.

Front 8

arthrography

Back 8

Process of x-raying the inside of a joint after a contrast medium (substance that makes the inside of the joint visible) has been injected into the joint.

Front 9

arthroplasty

Back 9

Surgical repair of a joint.

Front 10

Arthroscopy

Back 10

Visualization of the interior of a joint using an endoscope.

Front 11

rheumatoid factor

Back 11

A blood test that measures the presence of unusual antibodies that develop in a number of connective tissue diseases.

Front 12

Erythrocyte sed rate (ESR)

Back 12

Blood test that measures the rate at which erythrocytes settle in the bottom of the test tube filled with unclotted blood.

Front 13

Babinski's Reflex

Back 13

Tested by stroking the sole of the foot. Begins at midheel and moving upward and lateral to the toes. Positive result occurs when there is dorsiflexion of the great toe and fanning of the other toes.

Front 14

cerebral angiography

Back 14

Visualization of the cerebral vascular system via x-ray after the injection of the radiopaque contrast medium into an arterial blood vessel.

Front 15

CT scan of the brain

Back 15

Computerized tomographyis the analysis of a 3 dimensional view of brain tissue obtained as x-ray bones pass through successful horizontal layers of the brain.

Front 16

craniotomy

Back 16

Surgical procedure that makes an opening into the skull.

Front 17

echoencephalography

Back 17

Ultrasound used to analyze the intercranial structure of the brain.

Front 18

electroencephalography

Back 18

Measurement of electrical activity produced by the brain and recorded through electrodes placed on the scalp.

Front 19

laminectomy

Back 19

Surgical removal of the bony arches from one or more vertebrae to relieve pressure from the spinal cord.

Front 20

lumbar puncture

Back 20

Involves the insertion of a hollow needle and stylet into the subarachnoid space, generallly between the third and fourth lumbar vertebrae below the level of the spinal cord under strict aseptic technique.

Front 21

MRI of the brain

Back 21

Noninvasive scanning procedure provides visualization of fluid, and tissue, and bony structures without the use of radiation.

Front 22

Myelography

Back 22

Introduction of contrast medium into the lumbar subarachnoid space through a lumbar puncture in order to visualize the spinal cord and vertebral cord through x-ray examination.

Front 23

Positron Emission Tomography

Back 23

Produces computerized radiographic images of various body structures when radioactive substances are inhaled or injected.

Front 24

Romberg Test

Back 24

Used to evaluate cerebullar function and balances.

Front 25

Transcutaneous electrical nerve stimulation

Back 25

Form of cutaneous stimulation for pain relief that supplies electrical impulses to the nerve endings of a nerve close to the pain site.
