• Anatomic Terminology • 1/ Anatomic position • Erect, face forward, feet together, arms at sides with palms forward

• 2/Plane • Flat surface passed through the body or a portion of th body Longitudinal planes • Coronal • Sagittal Horizontal plane • Transverse Position

1 Coronal Plane. 2 Median Sagittal Plane. 3 Axial Plane

• 3/ Directional Terms lateral anterior cephalad cephalic superior cranial Posterior Anterior inferior caudal caudad distal Proximal Lateral Medial

4/ Joint Movement Terms • ABDUCT ADDUCT

• FLEXION EXTENSION

INVERSION EVERSION

ROTATION vs. CIRCUMDUCTION PRONATION vs. SUPINATION

5/ Body Position Terms • Describe the overall placement of the body Erect "upright" Position when the Sagittal and coronal planes of the body are perpendicular to the horizon.

• Recumbent "lying down" • Position when the transverse plane of the body is perpendicular to the horizon

• decubitus vs. recumbent • general meanings are the same "LYING DOWN" • but in radiography, decubitus has a special meaning DECUBITUS patient is lying down & the x-ray beam is parallel to the horizon
