Directional Terms & Movements Flashcards
Superior
Structure is closure to the vertex of the cranium.
Cranial
Structure is closest to the cranium.
Inferior
Structure is nearer the sole of the foot.
Caudal
Structure closest to the coccyx.
Posterior
Structure closest to the back/spine.
Anterior
Structure is closest to the front/sternum.
Rostral
Structure closest to the frontal lobe of the brain.
Medial
Structure that is closest to the median plane.
Lateral
Structure furthest from the median plane.
Dorsum
Superior portion of any anterior protruding body part. (I.e top of hand and top of foot)
Palmar
Inferior part of any anteriorly protruding body part. (I.e palms and soles)
Proximal
Structure closest to the limb attachment site
Distal
Structure furthest from the limb attachment site.
Flexion
Bending or decreasing an angle from its initial degree (up to 0).
Extension
Straightening or increasing an angle from its initial degree. (Up to 180).
Dorsiflexion
Flexion of the ankle joint. Moving the toes and foot superiorly.
Plantarflexion
Extension of the ankle joint. Moves the toes and foot inferiorly.
Abduction
Moving away from the midline/median plane (laterally).
Adduction
Moving towards the midline/median plane (medially)
Lateral flexion
Abduction of the trunk and head.
Circumduction
Circular movement around a joint.
- consists of abduction/abduction ; flexion/extension.
Medial rotation
Brings the anterior surface towards the longitudinal axis (median plan of structure)
Lateral rotation
Brings anterior surface away from the longitudinal axis (median plane).
Pronation
- Arms: rotates radius medially (palms face posteriorly).
- Foot: lowers median margin of the foot. Combo of eversion and abduction.
Supination
- Arms: rotates the radius laterally (palms face anteriorly).
- Foot: raises median margin of the foot. Combo of inversion and addiction.
Eversion
Foot: Rotates the ankle joint laterally; soles face away from the median plane.
Similar to pronation
Inversion
Foot: Rotates the ankle joint medially; soles face medially toward the median plane.
Opposition
Moves the 1st digit (thumb) towards the rest of the digits (usually touches 5th digit (pinky)).
Reposition
Moves the 1st digit (thumb) back to its anatomical resting position.
Protrusion
Moves a part anteriorly.
Retrusion
Moves a part posteriorly.
Elevation
Moves a part superiorly.
Depression
Moves a part inferiorly.
