Different Body Planes
| Question | Answer |
|---|---|
| Divides the entire body or a body part into right and left segments. The plane passes vertically through the body from front to back | Sagittal Plane |
| A specific sagittal plane that passes through the midline of the body and divides it into equal right and left halves | Midsagittal Plane |
| divides the entire body or a body part into anterior and posterior segments. The plane passes through the body vertically from one side to the other | Coronal Plane/Midaxillary Plane |
| specific coronal plane that passes through the midline of the body, dividing it into equal anterior and posterior halves | Midcoronal Plane |
| This plane divides the body into superior and inferior portions. | Horizontal Plane/Transverse Plane/Cross-sectional Plane |
| An oblique plane can pass through a body part at any angle among the three previously described planes | Oblique Plane |
| What is the Importance of Body Plane? | Planes are used in radiographic positioning to center a body part to the image receptor (IR) or central ray and to ensure that the body part is properly oriented and aligned with the IR. |
| What are the Two Special Planes? | 1. Ineriliac Plane 2. Occlusal Plane |
| It transects the pelvis at the top of the iliac crests at the level of the fourth lumbar spinous process | Interiliac Plane |
| formed by the biting surfaces of the upper and lower teeth with the jaws closed | Occlusal Plane |
| What are the 2 great cavities if the Torso? | 1. Thoracic Cavity 2.Abdominopelvic Cavity |

| What are the 4 major types of Body Habitus? | 1. Sthenic 2. Hyposthenic 3. Asthenic 4. Hypersthenic |
| Frequency of Sthenic | 50% |
| Frequency of Hyposthenic | 35% |
