Frontal
Abduction and adduction
Star jumps splits in gymnastics

Transverse
Rotation
Gymnastics pivots

Question 5

What are the planes and axis combinations?

Answer 5

Tranverse plane
Longitudinal axis
= rotational

Sagittal plane
Transverse axis
= flexion extension

Frontal plane
Sagittal axis
= abduction adduction

Answer 6

Hinge
Elbow knee ankle

Ball and socket
