Cervical

Flexion

Bending the joint resulting in a decrease of angle; moving the spine Forward; the neck moves toward the chest.
Cervical Spine Flexion

Extension / Hyperextension

Straightening the joint resulting in an increase of angle; moving the spine back; the neck moves away from the chest.
Cervical Spine Extension / Hyperextension

Lateral Flexion (Abduction)

Lateral movement away from the midline of the body; moving the spine to the side (left or right); the neck moves toward the shoulder.
Cervical Spine Lateral Flexion (Abduction)

Reduction (Adduction)

Return to the anatomical position from lateral movement; straightening the neck from lateral flexion.
 

Rotation

Rotary movement around the longitudinal axis of the bone; turning the spine to the side (right or left); the neck turns toward the shoulder.
 

Thoracic, Lumbar

Flexion

Bending the joint resulting in a decrease of angle; moving the spine forward; the thorax moves toward the pelvis.
Spinal Flexion

Extension / Hyperextension

Straightening the joint resulting in an increase of angle; moving the spine back; the thorax moves away from the pelvis.
Spinal Extension / Hyperextension

Lateral Flexion (Abduction)

Lateral movement away from the midline of the body; moving the spine to the side (left or right); the thorax moves to the side toward the pelvis.
Spinal Lateral Flexion (Abduction)

Reduction (Adduction)

Return to the anatomical position from lateral movement; straightening the spine from lateral flexion.
 

Rotation

Rotary movement around the longitudinal axis of the bone; turning the spine to the side (right or left); the thorax rotates to one side.
Spinal Rotation
