| facial hemiatrophy of Romberg | Atrophy of one half of the face which is sometimes progressive, and is of unknown cause. (12 Dec 1998) |
| anterior facial vein | <anatomy, vein> A continuation of the angular vein at the medial angle of the eye. It passes diagonally downward and outward, joining with the retromandibular vein below the border of the lower jaw before emptying into the internal jugular vein. Synonym: anterior facial vein, vena facialis anterior, vena facialis. (05 Mar 2000) |
|---|---|
| area of facial nerve | <anatomy, nerve> The area in the fundus of the internal acoustic meatus superior to the transverse crest through which the facial nerve passes to enter the facial canal. Synonym: area nervi facialis. (05 Mar 2000) |
| atypical facial neuralgia | Periodic pain in any region of the face, teeth, tongue, and occasionally in the occipital or shoulder area, which lasts several minutes to several days but has no trigger point and lacks the paroxysmal character of tic douloureux. Synonym: atypical facial neuralgia. (05 Mar 2000) |
| Broca's facial angle | The angle formed by the intersection at the biauricular axis of lines drawn from the supraorbital point and the alveolar point. Synonym: Broca's angles. (05 Mar 2000) |
| buccal branches of facial nerve | <anatomy, nerve> Motor branches of the facial nerve distributed to buccina or muscle and other muscles of facial expression below orbit and above chin. Synonym: rami buccales nervi facialis. (05 Mar 2000) |
| ganglion of facial nerve | The sensory ganglion of the facial (7th cranial) nerve. The geniculate ganglion cells send central processes to the brainstem and peripheral processes to the taste buds in the anterior tongue, the soft palate, and the skin of the external auditory meatus and the mastoid process. (12 Dec 1998) |
| velo-cardio-facial syndrome | <syndrome> Also known as shprintzen syndrome, this more than is a congenital malformation (birth defect) syndrome with cleft palate, heart defect, abnormal face, and learning problems. The condition is therefore called the velo-cardio-facial (vcf) syndrome. (the velum is the soft palate). Other less frequent features include short stature, small-than-normal head (microcephaly), mental retardation, minor ear anomalies, slender hands and digits, and inguinal hernia. The cause is usually a microdeletion in chromosome band 22q11.2, just as in digeorge syndrome. Vcf and digeorge syndromes are different clinical expressions of essentially the same chromosome defect. Of essentially the same chromosome defect. (12 Dec 1998) |
| geniculum of facial canal | The bend in the facial canal linking the medial and lateral crura of the horizontal port of the canal and corresponding to the location of the geniculate ganglion of the facial nerve. Synonym: geniculum canalis facialis. (05 Mar 2000) |
| geniculum of facial nerve | <anatomy, nerve> A rectangular bend of the facial nerve in the facial canal where it turns posterior in the medial wall of the middle ear (external geniculum), complex loop of facial nerve fibres around the abducens nucleus (internal geniculum). Synonym: geniculum nervi facialis. (05 Mar 2000) |
| marginal mandibular branch of facial nerve | <anatomy, nerve> Branch of facial nerve which parallels the mandibular margin innervating risorius muscle and muscles of lower lip and chin. Synonym: ramus marginalis mandibulae nervi facialis. (05 Mar 2000) |
| genu of facial canal | A sharp bend in the facial canal where the geniculate ganglion is located. (05 Mar 2000) |
