UTC Medical Terminology & Anatomy 2 — Questions and Answers
Question 1: The term 'echogenicity' refers to which property of tissue in ultrasound imaging?
- The ability of tissue to absorb sound waves
- The ability of tissue to reflect sound waves back to the transducer (Correct answer)
- The speed at which sound travels through tissue
- The density of tissue measured in Hounsfield units
Correct answer: The ability of tissue to reflect sound waves back to the transducer
Echogenicity describes how strongly a tissue reflects ultrasound waves back to the transducer, producing a signal on the image.
Question 2: Which anatomical plane divides the body into anterior and posterior sections?
- Sagittal plane
- Transverse plane
- Coronal plane (Correct answer)
- Oblique plane
Correct answer: Coronal plane
The coronal (frontal) plane divides the body into anterior (front) and posterior (back) portions.
Question 3: The prefix 'hepato-' refers to which organ?
- Kidney
- Spleen
- Liver (Correct answer)
- Pancreas
Correct answer: Liver
The prefix 'hepato-' is derived from Greek 'hepar,' meaning liver, as seen in terms like hepatomegaly.
Question 4: What does the term 'anechoic' describe in an ultrasound image?
- A structure that produces strong echoes
- A structure with no internal echoes, appearing black (Correct answer)
- A structure with mixed echogenicity
- A structure that attenuates sound completely
Correct answer: A structure with no internal echoes, appearing black
Anechoic structures transmit sound without producing echoes and appear completely black on ultrasound, as seen with simple fluid-filled cysts.
Question 5: The term 'nephro-' refers to which structure?
- Urinary bladder
- Ureter
- Kidney (Correct answer)
- Adrenal gland
Correct answer: Kidney
The prefix 'nephro-' derives from Greek 'nephros,' meaning kidney, as used in nephrology and nephrolithiasis.
Question 6: Which directional term means closer to the point of attachment or origin?
- Distal
- Lateral
- Proximal (Correct answer)
- Inferior
Correct answer: Proximal
Proximal means nearer to the point of attachment or origin, as opposed to distal which means farther away.
Question 7: The suffix '-itis' in medical terminology typically indicates:
- Surgical removal
- Inflammation (Correct answer)
- Abnormal enlargement
- Disease or condition
Correct answer: Inflammation
The suffix '-itis' denotes inflammation, as in appendicitis (inflammation of the appendix) or cholecystitis (inflammation of the gallbladder).
