| The supraorbital torus is lost in most modern humans, and ridging above the orbits in general is very reduced. |
| The supratrochlear nerve exits along the upper border of the orbit, approximately 1 cm medial to the supraorbital foramen. |
| With the patient looking directly ahead, palpate the supraorbital notch above the midline pupil in the mid-to-lower eyebrow. |
| Either mechanical tapping or electrical stimulation of the supraorbital regions may evoke the blink reflex. |
| During my dissection, I found that the muscle had a broad-based origin from near the midline to the supraorbital notch. |
| The posterior edge of the frontal is bilobate owing to the strongly notched exit of the supraorbital canal on to the parietal. |
