Review of Anatomy

What is Anatomy?

the science of the structure and function ofthe body

it is concerned with the study of living humanbeings


5/24

Review of Anatomy

Surface Anatomy

it is the visualization in the minds eye ofstructures that lie beneath the skin


6/24

Review of Anatomy

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

Review of Anatomy

! Medical Terminologies! internationally accepted Latin terms from the Nomina

Anatomica

!

eponyms! anatomical position! anatomical planes! sections of the body! terms of relationship! terms of comparison! terms of movement

Anatomical Position


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


11/24

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


12/24

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


13/24

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

Review of Anatomy

! Fascial planes! Head!

Neck! Potential Spaces! Head! Neck

! Skull and brain! Orbit! Ears!

Face and Nose! Oral Cavity & Pharynx! Larynx! Neck

Based on regions of Head and Neck


22/24

! discussing head and neck anatomy byregions

! convenient! easier to relate the structures with its function!

incorporate developmental anatomy andembryology

! better to understand radiological anatomy
