The Musculo-Skeletal System and Movement Analysis
Planes, axes and sagittal plane joint actions
- 3 things to know
- Paper 1
Overview
The sagittal plane and transverse axis, flexion, extension and hyperextension, plantar flexion and dorsiflexion, applied to kicking, sprinting, a bicep curl, a squat and a somersault.
What you need to know
Answer each one before you reveal it.
Define flexion, extension, hyperextension and plantar flexion.
What is the sagittal plane?
Questions from this subtopic
Each one with the model answer underneath.
- 1
What is the sagittal plane?
Model answer
The sagittal plane is a vertical plane that divides the body into left and right halves.
- 2
Which axis is paired with movement in the sagittal plane?
Model answer
Movement in the sagittal plane occurs about the transverse axis. The transverse axis runs horizontally from side to side through the body.
- 3
Which joint actions occur in the sagittal plane?
Model answer
Flexion, extension and hyperextension occur in the sagittal plane. Plantar flexion and dorsiflexion at the ankle also occur in the sagittal plane.
- 4
Define flexion.
Model answer
Flexion is a decrease in the angle between the bones at a joint.
- 5
Define extension and hyperextension.
Model answer
Extension is an increase in the angle between the bones at a joint. Hyperextension is an increase beyond 180 degrees, past the straight position.
- 6
What is plantar flexion?
Model answer
Plantar flexion is the ankle movement that points the toes away from the shin. Plantar flexion increases the angle at the ankle.
