| narrow-angle glaucoma | angle-closure glaucoma |
| neck-shaft angle | <orthopaedics> The angle formed by the meeting of a line drawn through the shaft of the femur with one passing through the long axis of the femoral neck; normally it is about 127 |
| sternal angle | The angle between the manubrium and the body of the sternum at the manubriosternal junction. Marks the level of the second costal cartilage (rib) for counting ribs or intercostal spaces. Denotes level of aortic arch, bifurcation of trachea, and T4/T5 intervertebral disc. Synonym: angulus sterni, Louis' angle, Ludwig's angle, manubriosternal junction. (05 Mar 2000) |
| sternoclavicular angle | The angle formed by the junction of the clavicle with the sternum. (05 Mar 2000) |
| subpubic angle | The angle formed between the inferior rami of the pubic bones. In the female, the angle approximates that angle between the widely extended thumb and index finger (90 |

| Daubenton's angle | An angle formed by the junction, at the opisthion, of lines coming from the basion and from the projection in the median plane of the lower border of the orbits. See: Daubenton's line, Daubenton's plane. Synonym: angulus occipitalis ossis parietalis, occipital angle of parietal bone. (05 Mar 2000) |
