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 appl...

7 fundamental measures of dimensional quantity - (s) -- mechanical h (m) - mechanical (kg) -- mechanical odynamic temperature - kelvin (K) ric current - ampere (A) osity - candela (cd) 7. amount of substance - mole (mol) 3 physical realities - Inertia Gravity Contact Properties of M...

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 func...

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...

3 articulations form synovial joints - - gleno-humeral (GH joint = the main "ball and socket" / enarthrosis) - sterno-clavicular (also 3 DoF, 2 significant, 1 limited) - acromio-clavicular (also 2 DoF, all 3 limited) 2 shoulder motion components - - scapulo-humeral (GHJ movement) - scapulo-t...

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 Ac...

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 ...

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 ...
