| frontal cortex | Cortex of the frontal lobe of the cerebral hemisphere, originally, the entire cortical expanse anterior to the central sulcus, including the agranular motor and premotor cortex (Brodmann's areas 4 and 6), the dysgranular cortex (area 8), and the granular frontal (prefrontal) cortex anterior to the latter, now more often refers to the granular frontal (prefrontal) cortex. Synonym: frontal area. (05 Mar 2000) |

| frontal eminence | The most prominent portion of the frontal bone on either side. Synonym: tuber frontale, eminentia frontalis, frontal tuber. (05 Mar 2000) |
| frontal fontanel | A diamond-shaped membranous interval at the junction of the coronal, sagittal, and metopic sutures where the frontal angles of the parietal bones meet the two ununited halves of the frontal bone. Synonym: fonticulus anterior, bregmatic fontanel, frontal fontanel. (05 Mar 2000) |

| frontal lobe epilepsy | A localization-related epilepsy with seizures originating in the frontal lobe. A variety of clinical syndromes exist depending on the exact localization of seizures and clinical semiology of the seizure type. Frontal lobe epilepsies have been divided into several specific syndromes including the syndrome of supplementary motor seizures, cingulate seizures, anterior frontal polar region seizures, orbital frontal seizures, dorsolateral seizures, opercular seizures, and seizures of the motor cortex.

| frontal margin | Edge of a bone which articulates with the frontal bone. See: frontal border of parietal bone, frontal border of sphenoid bone. Synonym: margo frontalis, frontal margin. (05 Mar 2000) |
| frontal nerve | <anatomy, nerve> A branch of the ophthalmic nerve which divides within the orbit into the supratrochlear and the supraorbital nerves. Synonym: nervus frontalis. (05 Mar 2000) |
| frontal notch | A small notch, sometimes a foramen, on the orbital margin of the frontal bone medial to the supraorbital notch. Synonym: incisura frontalis. (05 Mar 2000) |
| frontal plane | A vertical plane at right angles to a sagittal plane, dividing the body into anterior and posterior portions. Synonym: frontal plane. (05 Mar 2000) |
