| Distal | farthest from the point of attachment or origin |
| Posterior (dorsal) | back of body part |
| Proximal | nearer to the point of attachment or origin |
| Caudad | parts away from the head of the body; toward the feet |
| Cephalad | parts toward the head of the body; away from the feet |
| External | outside of the body |
| Internal | inside of the body |
| Superior | nearer the head or situated above |
| Inferior | nearer the feet or situated below |
| Parietal | the wall or lining of the body cavity |
| Visceral | the covering of the organs |
| Central | mid area or main part of an organ |
| Palmar | palms of the hand |
| Plantar | sole of feet |
| Dorsum | anterior, or top of the foot or the back of the hand |
| Lateral (direction) | away from the midplane of the body or away from the middle of the body part |
| Peripheral | at or near the surface, edge or outside of another body part (think PERImeter) |
| Ipsilateral | parts are on the same side of the body |
| Contralateral | parts are on the opposite side of the body (think CONTRAdiction) |
| Deep | far from the surface |
| Superficial | near the skin surface |
| Medial | toward the midplane of the body or toward the middle of the body part |

| Notch | indentation into border of a bone |
| Sinus | recess, groove, cavity, or hollow space |
| Sulcus | furrow or trench |
| Projection (positioning) | the path of the CR as it exits the xray tube, passing through the patient to the IR |
| Position | overall posture of the patient or general body position |
| View | the body part as seen by the IR; exact opposite projection |
| Method | a specific radiologic position developed by an individual |
| AP | CR enters the anterior surface and exits the posterior |
| PA | CR enters the posterior surface and exits the anterior |
| Axial | longitiudnal angle o the CR of 10 degrees or more |
| Tangential | CR directed along the outer margin of a curved body surface |
| Lateral (positioning) | CR enters one side of the body, passing transversely along the coronal plane |
| Oblique | CR enters from a side angle, entrance and exits surface still specific |
| Abduction | movement of a part away from the central axis of the body |
| Adduction | movement of a part toward from the central axis of the body |
| Extension | straightening of a joint |
| Flexion | bending of a joint |
