Lecture 2: Anatomical Orientation Flashcards
Anatomical Position
Picture of a person when structure is being described,
Standing upright, feet flat, arms at sides,
Palms, eyes, and face forward,
Left/right in reference to subject, not observer
Anterior/Ventral
Front,
Torso
Posterior/Dorsal
Back,
Torso
Superior
Toward the head,
Torso
Inferior
Toward the feet,
Torso
Lateral
Away from body midline,
Torso,
Extremities
Medial
Toward body midline,
Torso,
Extremities
Proximal
Near point of attachment,
Extremities
Distal
Far from point of attachment,
Extremities
Unilateral
One side affected/included,
Left or Right
Bilateral
Both sides affected/included,
Left and Right
Contralateral
Opposite side affected,
Ex: stroke patients
Deep
Away from body surface
Superficial
Toward body surface
Supine
Lying face up
Prone
Lying face down
Coronal Plane
Front/back division (frontal)
Sagital Plane
Left/right division
Transverse Plane
Upper/lower division (horizontal)
Flexion
Bending movement that results in decrease of the angle in a joint by bringing bones together
Extension
Opposite of flexion,
Straightening movement that results in an increase of the angle in a join by moving bones apart
Plantar Flexion
Bottom of foot flexion,
Pointing toes down (inferior),
Standing on toes
Dorsal Flexion/Dorsiflexion
Top of foot flexion,
Pulling toes up (superior),
Standing on heels
Abduction
Lateral movement away from the midline of the trunk (shoulder/hip)
Adduction
Movement medially toward the midline of the trunk
Lateral Flexion
Lateral bending only of the head or trunk
Elevation
Shoulder (scapulae),
Jaw (TMJ),
Superior movement,
Ex: Shrugging, closing jaw, etc
Depression
Shoulder (scapulae),
Jaw (TMJ),
Inferior movement,
Ex: Opening jaw
Protraction
Mandible anterior,
Jaw (TMJ)
Retraction
Mandible posterior,
Jaw (TMJ)
Eversion
Plantar laterally (out, pronation), Ankle
Inversion
Plantar Medially (in, supination), Ankle
Ulnar Deviation
Medial bone of forearm,
Wrist
Radial Deviation
Lateral bone of forearm,
Wrist
Rotation
Left and Right,
Head, neck, trunk
External (lateral) Rotation
Away from midline (shoulder/hip)
