Module 1 Review Flashcards
Kinematics
involves terms which describe the body’s movements
Kinetics
involves the study of forces which produce motion or maintain equilibrium
What are the four types of motion?
With reference to kinematics.
- rotation
- oscillation
- reciprocating
- translation
know the difference between them
What are the two types of translation?
- rectilinear
- curvilinear
What is general motion?
combination of rotary and translatory motions
rotation of an object about an axis while axis moves through space
Types of translatory joint movements:
- compression
- distraction
- gliding
What 3 characteristics do all vectors possess?
- point of application
- action line and direction
- magnitude
Where is the COG of the human body when erect?
anterior (slightly) to S2
Stability is easier to be achieved when the BOS is-
larger/wider
The lower the COG, the greater the-
stability
Friction Force
results in opposition to linear movement between two surfaces
Shear Forces
results in linear movement (sliding) between two contacting surfaces
Where is the axis in a first class lever?
between force and resisitance
What are first class levers best designed for?
balance and stability
What is an example of a first class lever?
seesaw
Where is the resistance in a second class lever?
between muscle force and axis
What are second class levers best used for?
power
What is an example of a second class lever?
wheelbarrow
Where is the force in located in a third class lever?
between resistance and axis
What are third class levers best designed for?
ROM and speed
The body consists majority of what types of levers?
third
Torque Equation
force x distance
moment of force
How many cranial nerve pairs are there?
12
How many spinal nerve pairs are there?
31
