Biomedical Engineering Exam 1
Questions & Answers (Grade A+)
What is biomedical engineering? -
correct answer ✅The application of principles of engineering,
math & physical science to problems in biology and medicine
Problems in BME? (2) -
correct answer ✅- modeling of normal or abnormal physiology
- research and design of instrumentation and machines for medical
diagnosis or therapy
BME branches (5) -
correct answer ✅- biomaterials
- biomechanics
- biomedical imaging
- biosensors and instrumentation
- tissue engineering
Biomaterials -
correct answer ✅Development of devices which are used to
enhance life processes (ex: biological/artificial heart)
,Biomedical Engineering Exam 1
Questions & Answers (Grade A+)
Biomechanics -
correct answer ✅The use of engineering or physics principles to
understand the performance of an organism
Biomedical imaging -
correct answer ✅The development and improvement of imaging
devices (ex: x-rays, MRIs, CAT scans, ultrasound
Biosensors and instrumentation -
correct answer ✅The development of sensors and data collection
systems to monitor and provide feedback on human body
processes (ex: contact lenses monitoring blood glucose levels for
diabetes)
Tissue engineering -
correct answer ✅development of mechanisms to regrow tissues,
mostly through provision of environments in which tissues may
grow (ex: through use of stem cells, 3D printing)
What was the first prosthetic to be used, where/when was it found
and when is it from? -
correct answer ✅Around 1,000 B.C. in Thebes Egypt - in 2002
, Biomedical Engineering Exam 1
Questions & Answers (Grade A+)
German archaeologists uncovered 3000 yr old mummy with a
wooden prosthetic tied to foot to serve as big toe
(thought more for aesthetic reasons rather than functional, but
found wear marks on bottom showing use)
What was the first documented biomedical instrument, who
developed it, when and why? -
correct answer ✅The stethoscope developed by Rene Laennec in
1816 because he didn't want to place his ear onto a young women's
bare chest so he used a rolled up newspaper --> inspired his
invention
Who developed electrophysiology, when and what did they do? -
correct answer ✅in 1848 Hermann von Helmholtz applied eng.
principles to a problem in physiology and determined resistance of
muscle and nervous tissue to direct current (before development of
lightbulb) - later led to EMG
When and who were X-rays invented by? How? -
correct answer ✅In 1895 Wilhelm Roentgen discovered cathode-
ray tube could make a paper coated in barium platinocyanide glow,
