what do lever systems do
they help the body to move
1 of 28
what is the lever arm
the bone or body part being moved about a point
it is shown as a straight line
2 of 28
what is the fulcrum
the joint where the lever arm pivots
it is shown as a triangle
3 of 28
what is the effort
it is the force applied by muscles to the lever arm
it is shown as an arrow
4 of 28
what is the load
it is the pull against the muscles to the lever arm eg: something being lifted
it is shown as a square or an arrow
5 of 28
what is a first class lever
it is the load and the effort at opposite ends of the lever and the fulcrum in the middle
6 of 28
what are the first class lever for
elbow exstention
7 of 28
what is a second class lever
it is the fulcrum and the effort at opposite ends of the lever and the load in the middle
8 of 28
what are the second class lever for
planter flexion and dorsiflexion at the ankle when standing
9 of 28
what is a third class lever
it is the fulcrum and the load at opposite ends of the lever and the effort in the middle
10 of 28
what are the third class lever for
elbow flexion and flexion and extension in the shoulder, hip and knee
11 of 28
what do levers have
mechanical advantage
12 of 28
what is the distance between the fulcrum and the effort called
the effort arm
13 of 28
what is the distance between the fulcrum and the load called
weight(resistance) arm
14 of 28
formula for mechincal advantage
effort arm/weight
15 of 28
what is a plane movement
it is an imaginary flat surface which runs through the body
16 of 28
what are the different types of planes
sagittal, transverse and frontal
17 of 28
what does the sagittal plane do
divides the body into left and right sides
18 of 28
what does the transverse plane do
dives the body into top and bottom
19 of 28
what does the frontal plane do
divides the body into front and back
20 of 28
what is an axis of movement
it is an imaginary line that runs through the body
21 of 28
what are the 3 types of axis
sagittal, longitudinal and transverse
22 of 28
what does the longitudinal axis do
runs through the body top to bottom
23 of 28
what does the transverse axis do
runs through the body left to right
24 of 28
what does the sagittal axis do
runs through the body front to back
25 of 28
what plane and axis would you use for flexion and extension eg: summersaults or a forward roll
sagittal plane and transverse axis
26 of 28
what plane and axis would you use for abduction or adduction eg: cartwheel
frontal plane and sagittal axis
27 of 28
what plane and axis would you use for rotation eg: full twist
transverse plane and longitudinal axis
28 of 28
