Define the difference between kinematics and kinetics  Kinematic - positional history - how a rigid body moves (how fast, when, where) Kinetics - energy,work and force - why it moves Difference between velocity and acceleration  Velocity vector - rate of change of displacement and distance Acceleration vector - rate of change of velocity Define work  The transfer of energy from one body to another Define power  The rate of work - the product of force + velocity Define...

How are connective tissues classified?  By the packing of collagen and the mechanical properties determined by ECM Describe structure of collagen  Molecules made of protein triple helix, fibres made of many molecules (like mini ropes), high tensile stiffness+strength Describe the passive LD response of cortical bone  Linearly elastic initially (Hook'es Law) + somewhat ductile Describe the LD response of cortical bone  Stiffer/tougher under compression than tension or sh...

Mechanisms of Head Injury  Loading can be direct or indirect (via neck = "whiplash") Direct loading can be Blunt = large contact area ⇒lower stress Focal / Sharp = small contact area ⇒higher stress Loading causes acceleration(F = m · a) and strain(σ= E · ε)of skull and brain Depending on exact mechanics, may hurt twice because of acceleration and subsequent deceleration Strain of brain and intracranial vessels  Strain of brain & intracranial vessels determined by ...

Intra-cellular (autobaric) loads  generated by the movement of organelles, cytoskeletal components, and the flow of fluids within the cell Para-cellular loads  - transmitted from cell to cell - directly or via ECM e.g. myofibre to tenocyte External Load Generation  forces or moments applied to organism from outside Compressive loads are ...  transmitted from ECM to cell membrane Tensile loads are...  transmitted from ECM to cytoskeleton by direct transmembrane p...

Define physical activity according to the lecture. How is it measured?  Physical activity is defined as any force exerted by skeletal muscles resulting in energy usage above resting levels. It's measured in volume (amount of energy expended) and intensity (rate of energy expenditure). What are the key components of health mentioned in the lecture?  The key components of health include physical, mental, social, and spiritual well-being. What is the difference between well-being...

autosomal dominant  inheritance pattern of a dominant allele on an autosome autosomal recessive  two copies of an abnormal gene must be present in order for the disease or trait to develop heterozygous  having two different alleles for a trait homozygous  having two identical alleles for a trait incomplete dominance  case in which one allele is not completely dominant over another, the phenotypes get mixed together (ex: pink) the phenotypes varies continuously with l...

what are the components of health?  physical, social, mental, spiritual, How does WHO define health? and the 2 important points  a state of complete physical, mental, and social well-being and not merely the absence of disease - holistic (many components to health) - implies capacity to function, enjoy, and perform WHO's definition measures disease over health? T or F  T What are quantitative indicators of disease?  - mortality (death rate/life span) - morbidity (...

What is articulation + what does it do  The contact between segments (contact patches between bones) + it contains relative motion of segments through contact and reaction force (compression) Differentiate between a join and a joint  A join constrains relative motion of segments through tension, a joint is a set of articulated bones + tissues - 2,3,4 bones involved What does it mean to have 6 DoF?  Can move in 3 orthogonal translations + 3 orthogonal rotations Segmental v...

What is weight used to calculate?  - nutirional status  - calculate medication dosages Edema  Retaining fluid What can changes in weight be a sign of?  Disease When are you supposed to monitor weight?  - Measure at the same time of day -measure with same type of clothes on and no shoes - always measure with empty bladder What do vital signs tell us?  Heart rate Blood pressure Temperature Respirations Pain is referred to as..... for inquiry mail me @ Best...

Which is protein? Muffins, Apple, hamburger, Ice Cream Which is a dairy product? Jell-O, Oranges, Ginger Ale, Ice Cream  Hamburger and Ice Cream What is necessary to know when thickening liquids for a resident?  Checks the orders of consistency, thicken all liquids on tray, add thicker gradually, let sit for 1 to 2 minutes to assure right consistency Calculate the intake of patient fluids 8 oz of coffee 12 oz of jello 6 oz of yogurt 4 oz of ice cream  720 ml  8 x 30 =...
