| Question | Answer |
|---|---|
| Main axis of the body, consists of head, neck, and trunk | Axial region |
| Region that consists of the limbs | Appendicular region |
| Portion of the axial region, consists of thorax, abdomen, pelvis, and perineum | Trunk |
| Plane that lies vertically and divides the body into anterior and posterior parts | Frontal (coronal) plane |
| Plane that runs horizontally from right to left, dividing the body into superior and inferior parts. (Cross-section) | Transverse (horizontal) plane |
| Vertical plane that divides the body into right and left parts. | Sagittal plane |
| Specific sagittal plane that lies exactly in the midline | Median or midsagittal plane |
| Sagittal planes offset from the midline | Parasagittal plane |
| Diagonal plane between horizontal and vertical | Oblique |
| Anatomical position | Stand erect Feet together (about 6 in apart) Face forward Upper extremities to the side Palms forward |
| Lying on the back | Supine |
| Lying on stomach | Prone |
| Toward the head or upper part of structure | Superior (cranal) |
| Away from head end or toward lower part of structure | Inferior (caudal) |
| Toward the front of the body | Anterior (ventral) |
| Toward or at the back of the body | Posterior (Dorsal) |
| Toward or at the midline of the body | Medial |
| Away from the midline of the body | Lateral |
| Between a more medial and a more lateral structure | Intermediate |
| Closer to the origin of the body part | Proximal |
| Farther from the origin of a body part | Distal |
| Toward or at the body surface | Superficial (external) |
| Away from the body surface, more internal | Deep (internal) |
| On the same side | Ipsilateral |
| On opposite sides | Contralateral |
