part 4: apply your knowledge

1. a soccer player kicks a ball by straightening the knee.

■ flexion ■ extension ■ abduction ■ rotation

1. a dancer spins on one foot.

■ flexion ■ extension ■ rotation ■ supination

Explanation:

Table Completion

Each movement is matched to its standard anatomical joint action and movement type based on human kinesiology definitions.

1. Frontal plane movements involve side-to-side motion; arm abduction fits this.
2. Rotational movements occur around the longitudinal (vertical) axis of a body part.
3. Abduction (moving away from midline) and adduction (moving toward midline) are direct opposite movements.

1. Straightening a joint is defined as extension.
2. Spinning around a vertical axis is rotational movement.

Answer:

Movement Description	Joint Action	Type of Movement
2. Straightening your knee to stand up	Knee Extension	Sagittal Plane Movement
3. Lifting your arm out to the side	Shoulder Abduction	Frontal Plane Movement
4. Lowering your arm back to your side	Shoulder Adduction	Frontal Plane Movement
5. Turning your head left and right	Cervical Rotation	Transverse Plane Movement
6. Turning your palm to face upward	Forearm Supination	Transverse Plane Movement
7. Pointing your toes downward	Ankle Plantarflexion	Sagittal Plane Movement
8. Rolling the sole of your foot inward	Foot Inversion	Frontal Plane Movement
