| The nerves we are going to examine are the overorbital and infraorbital ramifications of the trigeminus. |
| Evidence for therapsid fur centers on the presence of infraorbital pits and ridges in some lower Triassic cynodonts. |
| The infraorbital canal may be shifted laterally as far as the suture between the maxilla and zygomatic bones. |
| The opening of the infraorbital canal is sunk into a vacuity that penetrates the rostrum. |
| The one feature diagnostic of the order is the presence of a bony bar, or stay, beneath the eye, an extension of the second infraorbital bone. |
| Fourteen days after presentation the macaw was anesthetized for trephination of the infraorbital sinuses. |
