6. Anatomical Planes Planes relate to the body’s position in space
Frontal (coronal) plane
Transverse (horizontal) plane
Sagittal plane
Frontal plane
The frontal (coronal) plane is vertical and extends from one side of the body to the other.
Transverse plane The transverse (horizontal) plane is horizontal and divides the body into upper and lower segments.
Sagittal plane
The sagittal (median) plane is vertical and extends from the front of the body to the back.

7. Depict an exercise among each of the planes.
Frontal
Transverse
Sagittal planes

13. Terms Used to Describe Movement
Flexion
Extension
Try flexing and extending different body parts

14. Terms Used to Describe Movement
Plantar flexion is specific to the ankle joint. It occurs when you point your toes (e.g., when you stand on your tip toes).
Dorsiflexion occurs when you bend the ankle to bring the top of your foot closer to your shin.

15. Terms Used to Describe Movement
Abduction
Adduction

16. Terms Used to Describe Movement
Supination is rotating the wrist such that the palm of your hand is facing forward (e.g., when you catch a softball underhanded with one hand).
Pronation occurs in the opposite direction.
Supination = holding a try of “soup”

17. Terms Used to Describe Movement
Inversion is associated with the ankle joint. It is a result of standing on the outer edge of your foot (e.g., when you twist your ankle).
Eversion is a result of standing on the inner edge of your foot.

18. Terms Used to Describe Movement
External rotation results when you twist or turn a body part outward from the midline (eg., turning your toes outward).
Internal rotation results when you twist or turn a body part inward towards the midline.

Elevation
Depression

20. Terms Used to Describe Movement
Circumduction is a combination of flexion, extension, abduction, and adduction. An example of this movement occurs when a softball pitcher throws a ball with a “windmill” action.
