| frontal border of parietal bone | The margin of the parietal bone that articulates with the frontal bone. Synonym: margo frontalis ossis parietalis. (05 Mar 2000) |
| frontal border of sphenoid bone | The margin of the greater wing of the sphenoid bon that articulates with the frontal bone. Synonym: margo frontalis ossis sphenoidalis. (05 Mar 2000) |
| frontal process of zygomatic bone | The process of the zygomatic bone which extends upward to form the lateral margin of the orbit and articulates with the frontal bone and greater wing of the sphenoid bone. Synonym: frontosphenoidal process, processus frontalis ossis zygomatici. (05 Mar 2000) |
| jugular notch of occipital bone | The notch in the occipital bone which forms one boundary of the jugular foramen. Synonym: incisura jugularis ossis occipitalis. (05 Mar 2000) |
| jugular notch of temporal bone | The notch in the temporal bone which forms one boundary of the jugular foramen. Synonym: incisura jugularis ossis temporalis. (05 Mar 2000) |
| nasal bone | Either of two small elongated rectangular bones that together form the bridge of the nose. (12 Dec 1998) |
| nasal surface of palatine bone | The nasal surface of the perpendicular lamina of the palatine bone that forms part of the lateral wall of the nasal cavity, the nasal surface of the horizontal lamina of the palatine bone that forms part of the floor of the nasal cavity. Synonym: facies nasalis ossis palatini. (05 Mar 2000) |

| median frontal sulcus | A relatively shallow sagittal fissure of the brain dividing the middle frontal convolution into an upper and lower part; this sulcus is found only in humans and anthropoid apes; at its anterior extremity it bifurcates, the two branches spreading out laterally and constituting the frontomarginal sulcus. Synonym: median frontal sulcus, sulcus frontalis medius. (05 Mar 2000) |
| middle frontal convolution | A convolution on the convexity of each frontal lobe of the cerebrum running in an anteroposterior direction between the superior and inferior frontal sulci. Synonym: gyrus frontalis medius, middle frontal convolution. (05 Mar 2000) |
| middle frontal gyrus | A convolution on the convexity of each frontal lobe of the cerebrum running in an anteroposterior direction between the superior and inferior frontal sulci. Synonym: gyrus frontalis medius, middle frontal convolution. (05 Mar 2000) |
