Directional and Anatomical Location Terminology

Sports Medicine Injuries Learning Targets
  • Unit 1 Anatomical Directions and Movement
    Terminology
  • I can define terminology used to describe
    anatomical locations.
  • I can differentiate between the cardinal
    anatomical planes.
  • I can define terminology used to describe
    anatomical movements.
  • I can describe anatomical locations using correct
    medical terminology.
  • I can apply anatomical movement terminology to
    specific anatomical actions.

3
Anatomical Position
  • Anatomical position
  • Standard reference point
  • Body standing erect (upright)
  • Facing forward
  • Arms at side
  • Palms and toes directed forward

4
Reference Positions
  • Fundamental position
  • Similar to anatomical position
  • Arms more relaxed
  • Palms face inward
  • Relative angle
  • Included angle between two segments

5
Cardinal Planes
  • Sagittal
  • Left and right halves
  • Mediolateral axis
  • Midsagittal plane
  • Frontal (coronal)
  • Front and back halves
  • Anteroposterior axis
  • Transverse (horizontal)
  • Upper and lower halves
  • Longitudinal axis
  • Many other planes exist

6
  • Cranial / Superior
  • Caudal / Inferior

7
  • Anterior
  • Posterior

8
  • Ventral
  • Dorsal

9
  • Superficial
  • Deep

10
  • Medial
  • Lateral

11
  • Distal
  • Proximal

12
  • Ipsilateral on the same side
  • Contralateral on opposite sides

13
Flexion Extension
  • Flexion
  • Decreasing joint angle
  • Extension
  • Increasing joint angle
  • Hyperflexion
  • Flexion beyond normal range
  • Hyperextension
  • Extension beyond normal range

14
Abduction Adduction
  • Abduction
  • Moving away from midline
  • Adduction
  • Moving toward midline
  • Hyperabduction
  • Abduction past 180 point
  • Hyperadduction
  • Adduction past 0 point

15
Movement Descriptors
  • Circumduction
  • Movement in a conic fashion
  • Combination of flex, ext, abd, add, IR, ER

16
Movement Descriptors
  • Inversion
  • Lift medial edge of foot
  • Eversion
  • Lift lateral edge of foot

17
Movement Descriptors
  • Plantarflexion
  • Increase angle between foot and shank
  • Dorsiflexion
  • Decrease angle between foot and shank

18
Movement of the Scapulae
  • Elevation raising the scapula (shrug)
  • Depression lowering the scapula

19
Movement of the Scapulae
  • Protraction move scapulae apart
  • Retraction move scapulae together

20
Movement of the Scapulae
  • Upward rotation bottom of scapula moves away
    from trunk
  • Downward rotation return to normal

21
Other Movement Descriptors
  • Horizontal adduction
  • Combination of flexion and adduction
  • Horizontal abduction
  • Combination of extension and abduction

22
Other Movement Descriptors
  • Rotation
  • Medial (internal) or lateral (external)
  • Right/left for head and trunk
  • Shoulder or hip

23
Other Movement Descriptors
  • Medial/Internal Rotation rotation of the bone
    inward around the long axis of the bone

24
Other Movement Descriptors
  • Lateral/External Rotation rotation of the bone
    outward around the long axis of the bone

25
Specialized Movement Descriptors
  • Lateral Flexion
  • Head or trunk only
  • Example head tilts sideways

26
Specialized Movement Descriptors
  • Supination turn palms frontward
  • Pronation turn palms backward
  • Radial flexion hand toward thumb
  • Ulnar flexion hand toward little finger
  • Opposition Thumb to little finger

27
Movement Descriptors of the Foot
  • Plantarflexion
  • Increase angle between foot and shank
  • Dorsiflexion
  • Decrease angle between foot and shank
  • Inversion
  • Lift medial edge of foot
  • Eversion
  • Lift lateral edge of foot

28
Pronation and Supination of the Foot
  • Pronation and supination of the feet are not the
    same as inversion and eversion
  • Pronation of the foot
  • Dorsiflexion at the ankle
  • Eversion in the tarsals
  • Abduction of the forefoot
  • Supination of the foot
  • Plantarflexion at the ankle
  • Inversion in the tarsals
  • Adduction of the forefoot

29
Specialized Movement Descriptors
  • Anterior Tilt
  • Posterior Tilt
  • Lateral Tilt

30
Degrees of Freedom
  • Degree of freedom
  • Number of planes in which a joint has the ability
    to move
  • 1 degree of freedom
  • Uniaxial
  • Example Elbow
  • 2 degrees of freedom
  • Biaxial
  • Example Wrist
  • 3 degrees of freedom
  • Triaxial
  • Example Shoulder
