How does Flexion occur?
Reducing the angle between the bones of a limb at a joint: muscles contract, moving the joint into a bent position
What are examples of flexion?
Bending the elbow
Bicep curl
How does Extension occur?
Straightening a limb to increase the angle at the joint
What is an example of extension?

How does Dorsi-Flexion occur?

What is an example of dorsi-flexion?
Toes upwards when hurdling
How does Plantar-Flexion occur?

Toes pointed when diving in the pike position
How does Lateral Flexion occur?
The movement of bending sideways
What is an example of lateral flexion?

How does horizontal flexion and extension occur?

What is an example of horizontal flexion and extension?
Bending and straightening of the elbow when it is out in front of you

Involves movement beyond the normal anatomical position in a direction opposite to flexion
What is an example of hyper extension?
