Question | Answer |
---|---|
Product Liability | having legal responsibility for failure of the product |
Reliability | the probability of satisfactory operation of the product in a given environment over a specified time interval |
Design | translation of a concept into a producible satisfactory salable product |
Data | information used a basis for reasoning or decision making |
Case Study | broad based analysis of an engineering problem |
Appendicular | 126 bones of upper and lower extremities |
Axial skeleton | 80 bones of skull, spinal column, ribs, sternum and hyoid bone |
Joint | bone meets bone, held together by ligaments; synovial fluid lubricates |
Ball and socket joint | moveable such as hip and shoulder joints; sphere head of one bone fits into socket of another bone |
Gliding joint | example would be between vertebrae, surfaces are almost planes such as metacarpals; difference is in the shape of two bones |
Hinge joint | movement in 1 direction, unilateral joint, example knee joint or elbow |
Diarthroses | joints with free movement |
Syntharthroses | joints with no movement; example might be sutures of skull |
Condylarthrosis | a joint like the knee formed by a rounded bone at the extremity of a bone |
Biocompatibility | use of various materials to replace human components without adverse results |
Saddle joint | biaxial synovial joint in which the double motion is affected by opposition of two surfaces as in the thumb |
Orthopedic implant | device inserted to repair orthopedic injury or diseases |
Atrium | chambers of the heart where blood is received from body before going to ventricles |
Ventricle | chambers in the heart receiving blood from atrium on same side, pumps blood into arteries |
bicuspid valve | located between L atrium and L ventricle; also known as mitral valve |
mitral valve | located between L atrium and L ventricle, controls blood flow |
semilunar valve | half moon shaped valve which prevents blood from flowing back into heart |
artery | muscular walled and elastic walled blood vessel that carries oxygenated blood from heart to body |
capillary | smallest of the body's blood vessels |
tricuspid valve | controls blood flow from R atrium to R ventricle |
atrioventricular valve | prevents return of blood to the atrium |
P wave | first upward wave in an ECG which indicates the atrial depolarization |
T wave | 3rd wave in an ECG which indicates ventricular repolarization |
Sinoatrial node | pacemaker of the heart |
Pacemaker | electronic device which is surgically implanted into the pt. heart and chest to regulate heartbeat |
Pericardium | membranous sac surrounding the heart and major blood vessels connected to it |
Pulse | rate at which the heart beats, rhythmic contraction and expansion of arteries with each beat of the heart |
Nanotechnology | a branch of science and engineering devoted to design and production of extremely small electronic devices and circuits built from atoms and molecules |
Stent | slender rod, thread, or catheter inserted into a tubular structure such as a blood vessel to provide support during or after anastomosis |
QRS Complex | the 2nd wave of an ECG and it is associated with the depolarization of the ventricles |
Myocardial infarction | result of permanent damage to an area of heart muscle |
ECG | electrocardiogram, test which records the electrical activity of the heart, shows abnormal rhythm and heart muscle damage |
