Presentation on theme: "Body Regions & Anatomical Terminology"— Presentation transcript:
1 Body Regions & Anatomical Terminology Objective 1: Identify and utilize anatomical positions, planes, and directional terms.Objective 2: Demonstrate body movements.
2 Anatomical Position Arms down by side Palms up Head and eyes forward Legs parallel, feet together
3 Anatomical Planes Frontal Plane (Coronal Plane) Sagittal Plane Divides the body into front and back portions.Sagittal PlaneDivides the body into right and left portions.Midsagittal – body is divided into EQUAL right and left portionsTransverse Plane (Horizontal Plane)Dividing the body into upper and lower portions
4 Anatomical Position & Directions Terms of position and direction to describe the position of one body part relative to another, usually along one of the three major body planesAnterior – a structure being more in front than another structure of the bodyPosterior – a structure being more in back than another structure in the body
5 Anatomical Position & Directions Superior – refers to a structure being closer to the head or higher than another structure in the bodyInferior – refers to a structure being closer to the feet or lower than another structure in the body
6 Anatomical Position & Directions Medial – refers to a structure being closer to the midline or median plane of the body than another structureLateral – refers to a structure being farther away from the midline than another structure of the body
7 Anatomical Position & Directions Proximal – refers to a structure being closer to the root of the limb than another structure in that limbDistal – refers to a structure being further away from the root of the limb than another structure in that limbReference to extremities only
8 Anatomical Positions & 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
9 Anatomical Positions & Directions VentralTowards the front/bellyYou Vent out o your nose and mouth.DorsalTowards the backLike the Dorsal fin of a dolphin.
10 Ventral – Black Dorsal – White Humans are bipedal, we walk on two legs, therefore our Ventral side / Dorsal side flips at our lower extremities. Ventral – Black Dorsal – WhiteVentral – Black Dorsal – White
11 Anatomical Positions & 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
13 Movements Flexion Extension Hyperextension Bending 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.
15 Movements Adduction Moving a body part towards the midline of the body AbductionMoving a body part away from the midline of the body
16 Movements Pronation Turning the arm or foot downward Supination (palm or sole of the foot - down)SupinationTurning the arm or foot upward(palm or sole of the foot - up)
17 Movements Retraction Protraction Elevation Depression Moving a part backwardProtractionMoving a part forwardElevationRaising a partDepressionLowering a part
18 Movements Rotation Circumduction External rotation Internal rotation Turning on a single axisCircumductionTri-planar, circular motion at the hip or shoulderExternal rotationRotation of the hip or shoulder away from the midlineInternal rotationRotation of the hip or shoulder toward the midline
19 MovementsLateral FlexionSide-bending left or right
20 Movements of the Foot Inversion Eversion Dorsiflexion Plantarflexion Turning the sole of the foot inwardEversionTurning the sole of the foot outwardDorsiflexionAnkle movement bringing the foot towards the shinPlantarflexionAnkle movement pointing the foot downward
21 Movements 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.
