| gyrus frontalis inferior | 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) |
| gyrus frontalis medius | 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) |
| gyrus frontalis superior | 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) |
| musculus frontalis | See: occipitofrontalis muscle. (05 Mar 2000) |
| polus frontalis cerebri | The most anterior promontory of each cerebral hemisphere. Synonym: polus frontalis cerebri, frontal pole. (05 Mar 2000) |
| crista frontalis | 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) |
| hyperostosis frontalis interna | <radiology> Overgrowth of bone at the inner table of the frontal bone, usually bilateral and symmetrical, chiefly in females greater than 35 y.o., no clinical siginificance, unknown aetiology, irregular cortical thickening of the frontal area, spares areas occupied by superior sagital sinus and venous channels, may be 1 cm or thicker, occasionaly extends to parietal bones and orbital roofs, hyperostosis calvariae diffusa: variant of HFI: more diffuse thickening of vault (involving both tables) see: increased skull thickness (12 Dec 1998) |
| sinus frontalis | One of the paired, but seldom symmetrical, air spaces located between the inner and outer compact layers of the frontal bone. (12 Dec 1998) |
| spina frontalis | S, nasalis ossis frontalis. (05 Mar 2000) |
| spina nasalis ossis frontalis | A projection from the centre of the nasal part of the frontal bone, which lies between and articulates with the nasal bones and the perpendicular plate of the ethmoid. Synonym: spina nasalis ossis frontalis. (05 Mar 2000) |
| squama frontalis | The broad curved portion of the frontal bone forming the forehead. Synonym: squama frontalis. (05 Mar 2000) |
| nervus frontalis | <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) |
| norma frontalis | The outline of the skull viewed from in front. Synonym: norma anterior, norma frontalis. (05 Mar 2000) |
| sulcus frontalis inferior | 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) |
