Planes and Movement (EXAM 1) Flashcards
Sagittal Plane
- Divides body into right and left halves
- Forward and backward motions (flexion, extension)
- Rotary motion in sagittal plane occurs around a coronal axis
Frontal Plane
- Divides body into front and back halves
- Side-to-side movements or lateral/medial movements (abduction, adduction, radial/ulnar deviation, lateral flexion, inversion, eversion, and flexion & extension of thumb)
- Rotary motion in frontal plane occurs around an anterior-posterior axis
Traverse (horizontal) Plane
- Divide body into upper and lower halves
- Movements occur parallel to ground (rotary motions, horizontal abduction/adduction)
- Rotary motion occurs around a longitudinal or vertical axis
Flexion
Movement in the sagittal plane, from anatomical position
Extension
Movement in the sagittal plane, back to anatomical position
Abduction
Movement in the frontal plane, away from the midline of the body or segment
Adduction
Movement in the frontal plane, toward the midline of the body or segment
External rotation
Movement in the transverse plane, reference point turns away from midline or reference point of the body
Internal rotation
Movement in the transverse plane, reference point turns toward the midline or reference point on the body
Horizontal abduction
Movement in the transverse plane, away from the midline of the body (used for hip and shoulder)
Horizontal adduction
Movement in the transverse plane, toward the midline of the body
Lateral flexion
Movement in the frontal plane, away from the midline of the body (neck/trunk)
Inversion
Foot movement, reference segment moves toward midline
Eversion
Foot movement, reference segment moves away from midline
Supination
- Foot movement (triplanar) combination of inversion, horizontal adduction and plantar flexion (all referenced to the calcaneus)
- Forearm movement - turning the palm of the hand up
