| superior frontal gyrus | A broad convolution running in an anteroposterior direction on the medial edge of the convex surface and of each frontal lobe. Synonym: gyrus frontalis superior, marginal gyrus, superior frontal convolution. (05 Mar 2000) |
|---|---|
| superior frontal sulcus | A sagittal fissure on the superior surface of each frontal lobe of the cerebrum starting from the precentral sulcus; it forms the lateral boundary of the superior frontal convolution. Synonym: sulcus frontalis superior. (05 Mar 2000) |
| inferior frontal convolution | A broad convolution on the convexity of the frontal lobe of the cerebrum between the inferior frontal sulcus and the sylvian fissure; divided by branches of the sylvian fissure into three parts: pars (opercularis) basilaris, triangular part, and orbital part; the first two constitute a portion of the frontal operculum. Synonym: gyrus frontalis inferior, inferior frontal convolution. (05 Mar 2000) |

Synonym: gyrus frontalis inferior, inferior frontal convolution. (05 Mar 2000) |
| inferior frontal sulcus | A sagittal fissure on the lateral convex surface of each frontal lobe of the cerebrum demarcating the middle from the inferior frontal gyrus. Synonym: sulcus frontalis inferior. (05 Mar 2000) |
| epilepsy, frontal lobe | Epileptic seizures arising from the frontal lobe characterised by simple partial, complex partial, secondary generalised seizures, or combinations of these. The seizures, which are short in duration, may occur several times a day, mostly during sleep. Affected individuals usually have prominent motor manifestations which are tonic or postural, complex gestational automatisms at the onset, and fall to the ground when the discharge is bilateral. Status epilepticus is a frequent complication. (12 Dec 1998) |
| frontal | Belonging to the front part; being in front; especially. <anatomy> . Of or pertaining to the forehead or the anterior part of the roof of the brain case; as, the frontal bones. Origin: Cf. F. Frontal. 1. Something worn on the forehead or face; a frontlet; as: An ornamental band for the hair. The metal face guard of a soldier. 2. A little pediment over a door or window. 3. A movable, decorative member in metal, carved wood, or, commonly, in rich stuff or in embroidery, covering the front of the altar. Frontals are usually changed according to the different ceremonies. 4. <medicine> A medicament or application for the forehead. 5. <anatomy> The frontal bone, or one of the two frontal bones, of the cranium. Frontal hammer or helve, a forge hammer lifted by a cam, acting upon a "tongue" immediately in front of the hammer head. Origin: F. Frontal, fronteau, OF. Frontel, frontal, L. Frontale an ornament for the forehead, frontlet. See Front. Source: Websters Dictionary (01 Mar 1998) |
| frontal area | 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 artery | <anatomy, artery> Origin, ophthalmic; distribution, anterior portion of scalp; anastomoses, branches of supraorbital. Synonym: arteria supratrochlearis, arteria frontalis, frontal artery. (05 Mar 2000) |
| frontal belly of occipitofrontalis muscle | <anatomy> The anterior belly of the occipitofrontalis muscle. See: occipitofrontalis muscle. Synonym: venter frontalis musculi occipitofrontalis, frontalis muscle. (05 Mar 2000) |
| frontal border | 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 branch of superficial temporal artery | <anatomy, artery> Terminal branch of superficial temporal artery (with parietal branch) supplying anterolateral scalp and underlying musculature, periosteum, and outer table of cranium; anastomosis: across midline with contralateral partner; supratrochlear and supraorbital arteries. Synonym: ramus frontalis arteriae temporalis superficialis. (05 Mar 2000) |
| 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 crest | A ridge arising at the termination of the sagittal sulcus on the cerebral surface of the frontal bone and ending at the foramen caecum. Synonym: crista frontalis. (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) |
