1Medical Terminology Anatomical Position, Directional Terms and Movements
2What we will cover... Content Objectives Language Objectives Students will be able to gain a better understanding and application of medical terminology in relation to Anatomical Planes, Directions and Movements.Language ObjectivesStudents will be able to define basic anatomical terms and apply those terms when dissecting.Students will be able to compare and contrast the differences between directional terms and terms associated with movement.
4HistoryDuring the Renaissance (“Rebirth”) the study of human life and medicine began to flourish.Scientist, Doctors and Artist would experiment and practice on the dead and incarcerated.Cadavers were positioned flat on their backs, thus making it easier to draw and reference from that position.Many artist such as Leonardo da Vinci began to study, draw and diagram the human body.
5Anatomical Position Standing erect, with palms and feet facing forward Is the standard reference point in which all positions, movements, and planes are described
6Positions and Directions Terms of position and direction describe the position of one body part relative to another, usually along one of the three major body planes
7Positions and Directions SuperiorRefers to a structure being closer to the head or higher than another structure in the bodyInferiorRefers to a structure being closer to the feet or lower than another structure in the body
8Positions and Directions AnteriorRefers to a structure being more in front than another structure in the bodyPosteriorRefers to a structure being more in back than another structure in the body
9Positions and Directions MedialRefers to a structure being closer to the midline or median plane of the body than another structure of the bodyLateralRefers to a structure being farther away from the midline than another structure of the body
10Positions and Directions RootDistal(Reference to the extremities only)Refers to a structure being further away from the root of the limb than another structure in the limbProximalRefers to a structure being closer to the root of the limb than another structure in that limbRoot
11Distal / Proximal Cont.When you divide the skeleton into Axial (Blue) and Appendicular (Yellow) you can better understand the extremities and their roots.ProximalDistalRoot
12Positions and Directions SuperficialRefers to a structure being closer to the surface of the body than another structureDeepRefers to a structure being closer to the core of the body than another structure
13Positions and Directions VentralTowards the front or bellyYou Vent out or your nose and mouth.DorsalTowards the backLike the Dorsal fin of a dolphin.
14Positions and Directions ProneLying face downLike a Pro Baseball player sliding into Home.SupineLying face upLying on your spine and you can have soup poured into your mouth.UnilateralPertaining to one side of the bodyBilateralPertaining to both sides of the body
15Anatomical PlanesFixed lines of reference along which the body is often divided or sectioned to facilitate viewing of its structuresAllow one to obtain a three-dimensional perspective by studying the body from different views
16Anatomical Planes Sagittal plane The plane dividing the body into right and left portionsMidsagittal or median are names for the plane dividing the body into equal right and left halves
17Anatomical Planes Frontal plane The plane dividing the body into front and back portionsAlso called the Coronal plane
18Anatomical Planes Transverse plane The horizontal plane dividing the body into upper and lower portionsAlso called the Horizontal plane
21MovementsFlexionBending a joint or decreasing the angle between two bonesIn the Fetal Position we are flexing our jointsExtensionStraightening a joint or increasing the angle between two bonesIn the Anatomical Position we are extending our jointsHyperextensionExcessive extension of the parts at a joint beyond anatomical position.
23Movements Adduction Moving a body part towards the midline of the body AbductionMoving a body part away from the midline of the body
24Movements Pronation Turning the arm or foot downward (palm or sole of the foot - down)ProneSupinationTurning the arm or foot upward(palm or sole of the foot - up)Supine
25Movements Retraction Moving a part backward Protraction Moving a part forwardElevationRaising a partDepressionLowering a part
26Movements Rotation Turning on a single axis Circumduction Tri-planar, circular motion at the hip or shoulderInternal rotationRotation of the hip or shoulder toward the midlineExternal rotationRotation of the hip or shoulder away from the midline
27MovementsLateral FlexionSide-bending left or right
28Movements of the Foot Inversion Turning the sole of the foot inward EversionTurning the sole of the foot outwardDorsiflexionAnkle movement bringing the foot towards the shinPlantarflexionAnkle movement pointing the foot downward
29Movements of the Wrist & Thumb Radial DeviationMovement of the wrist towards the radius or lateral side.Ulnar DeviationMovement of the wrist towards the ulna or medial side.OppositionMovement of the thumb across the palm of the hand.
