Soc 21: Planes And Lever Systems Flashcards
What is a plane?
A plane is a theoretical division of the body that are used to describe movement in the body.
How many planes are there?
3
Name the three planes?
Sagittal plane
Frontal plane
Transverse plane
Where is the sagittal plane and what does it result in as well- what types of movement can be made?
It divides the body from top to bottom(vertically), resulting in a left side and a right side- flexion and extension.
Where is the frontal plane and what does it result in as well- what types of movement can be made?
It divides the body from top to bottom (vertically), but front and back sections- adduction and abduction.
Where is the transverse plane and what does it result in as well- what types of movement can be made?
It divides the body across the middle (horizontally), giving a top section (superior) and a bottom section (inferior)- rotation.
What is an axis?
An axis is an imaginary line at right angles to the plane, where the body rotates or spins.
What axis is at 90° to the sagittal plane?
Frontal axis
What axis is at 90° to the frontal plane?
Sagittal axis
What axis is at 90° to the transverse plane?
Vertical axis
Give one example as to when a movement is made around the sagittal plane and the frontal axis? (Describe how the body moves).
Forward roll in gymnastics which results in a piked or tucked somersault.
You move forward, with your left and right sides both moving in the same direction- in the sagittal plane
Your body bends on a line that runs horizontally from side to side around your frontal axis.
Give one example as to when a movement is made around the frontal plane and the sagittal axis? (Describe how the body moves)
When somebody performs a cartwheel it is done on the frontal plane and around the sagittal axis.
You move sideways, from right to left or left to right- in the frontal plane.
Your body rotates around a line that runs along from the front to the back of your body- around your sagittal axis.
Give one example as to when a movement is made around the transverse plane and the vertical axis? (Describe how the body moves)
When a trampolinist does a twist they travel in the transverse (horizontal) plane around the vertical axis.
The key movement is around one spot (like a hula-hoop around the body) in the transverse plane.
They twist around an invisible line that runs from head to toe- around the vertical axis.
The sagittal plane (flexion and extension)=?
The frontal axis (flexion and extension)- Front somersault.
The frontal pane (abduction and adduction)=?
The sagittal axis (abduction and adduction)- Cartwheel
