| What is the plane that divides the body into equal anterior and posterior halves? | Midcoronal plane (MCP) |
| What is the plane that divides the body axially into superior and inferior portions? | Transverse/horizontal plane |
| What positioning term refers to the body's physical position, i.e. recumbent, erect, prone, supine, etc.? | Radiographic position |
| What positioning term describes the path of the CR i.e. PA, AP? | Radiographic projection |
| What positioning term describes the body part as seen by the IR and is infrequently used? | Radiographic view |
| What term describes lying down in any position? | Recumbent |
| What term describes lying on back, face up? | Supine |
| What term describes lying on abdomen, face down? | Prone |
| What term describes lying supine, prone, or lateral, using a horizontal CR? | Decubitus |
| What position is described as erect/upright/standing or sitting up facing the IR? | Anterior position |
| What position is described as erect/upright/standing or sitting up with back toward the IR? | Posterior position |
| True of False. The oblique position can be achieved in the erect or recumbent position? | True |
| Name the position. Body rotated, with right anterior aspect nearest the IR. | RAO/Right Anterior Oblique |
| Name the position. Body rotated, with left anterior aspect nearest the IR. | LAO/Left Anterior Oblique |
| Name the position. Body rotated, with right posterior aspect nearest the IR. | RPO/Right Posterior Oblique |
| Name the position. Body rotated, with left posterior aspect nearest the IR. | LPO/Left Posterior Oblique |
| Name the body habitus. 5%, body large and heavy, bony framework thick short and wide, high lungs and heart, stomach transverse, colon/ large bowel peripheral, gall bladder high and lateral. | Hypersthenic |
| Name the body habitus. 10%, body slender and light, bony framework delicate, thorax long and narrow, stomach low and long ("fish hook"), colon large bowel low, medial and redundant, gallbladder low and medial. | Asthenic |
| Name the body habitus. 50%, build average and athletic, similar to hypersthenic, but modified by elongation of abdomen and thorax. | Sthenic |
| Name the body habitus. 35%, somewhat slighter, less robust, similar to asthenic but stomach, intestines, and gallbladder situated higher in abdomen. | Hyposthenic |
