| epidural block | An obstruction in the epidural space; used inaccurately to refer to epidural anaesthesia. (05 Mar 2000) |
|---|---|
| exit block | Inability of an impulse to leave its point of origin, the mechanism for which is conceived as an encircling zone of refractory tissue denying passage to the emerging impulse. (05 Mar 2000) |
| fascicular block | A condition based on the concept that the left branch of the bundle of His provides two of three major fascicles of a system of conduction, of which the right bundle branch constitutes the third, for the transmission of the cardiac impulse from the atrium above to the ventricles below the A-V node; block may occur in any or all fascicles, all three together producing complete A-V block. See: hemiblock. (05 Mar 2000) |
| unidirectional block | Block that prevents passage of an impulse when it approaches from one direction but not from the other, as when block in the A-V node prevents anterograde conduction to the ventricles while retrograde conduction to the atria remains intact. (05 Mar 2000) |
| field block | Regional anaesthesia produced by infiltration of local anaesthetic solution into tissues surrounding an operative field. (05 Mar 2000) |
| field block anaesthesia | Conduction anaesthesia in which small nerves are not anaesthetised individually, as in nerve block anaesthesia, but instead are blocked en masse by local anaesthetic solution injected to form a barrier proximal to the operative site. (05 Mar 2000) |
| first degree A-V block | See: atrioventricular block. (05 Mar 2000) |

| 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) |
| 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) |
| 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) |
| genu of facial canal | A sharp bend in the facial canal where the geniculate ganglion is located. (05 Mar 2000) |
| glandular branches of facial artery | <anatomy, artery> Branches of facial artery to the submandibular gland. Synonym: rami glandulares arteriae facialis. (05 Mar 2000) |
