Radiological Anatomy
the study of the structure and function of the
body using radiographic techniquesan important part of anatomy; the sooner you
learn to identify normal structures onradiographs, the easier it is for you torecognize disease and injuries

Anatomical Position
8/10/2019 DGENAN2 L101 Introduction to Anatomy II 2014
10/24
Anatomical PlanesMedian plane imaginary verticalplane passing longitudinally
dividing the body into right andleft halves
Sagittal planes vertical planesparallel to the median plane
Coronal planes imaginaryvertical planes perpendicularto the median plane, dividingthe body into front and backportions
Horizontal planes perpendicularto both median and coronalplanes dividing the body intoupper and lower parts

Sections of the body
Longitudinal sections along the long axis of thebody and may be cut in median, sagittal andcoronal planes
Transverse sections slices of the bodyperpendicular to its long axis
Oblique sections slices that are not cut along the
anatomical planes; they slant or deviate fromthese planes

Terms of Relationship
Superior (cranial) nearer to head
inferior (caudal) nearer to feet
Anterior (ventral) nearer to front
Posterior (dorsal) nearer to back
medial nearer the median plane
lateral farther from the median plane

Terms of RelationshipProximal nearer to the trunk or point of origin
Distal Farther from the trunk or point of origin
Superficial nearer to or on the surface
Deep farther from the surface
external (outer) toward or on the exterior
internal (inner) toward or in the interior
central nearer or toward the center
peripheral farther or away from the center
