| P face | Method of specimen preparation for the electron microscope in which rapidly frozen tissue is cracked so as to produce a fracture plane through the specimen. The surface of the fracture plane is then shadowed by heavy metal vapour, strengthened by a carbon film and the underlying specimen is digested away, leaving a replica that can be picked up on a grid and examined in the transmission electron microscope. The great advantage of the method is that the fracture plane tends to pass along the centre of lipid bilayers and it is therefore possible to get en face views of membranes that reveal the pattern of Integral membrane proteins. The E face is the outer lamella of the plasma membrane viewed as if from within the cell, the P face the inner lamella viewed from outside the cell. Fracture planes also often pass along lines of weakness such as the interface between cytoplasm and membrane, so that outer and inner membrane surfaces can be viewed. Further information about the structure can be revealed by freeze etching. Extremely rapid freezing followed by deep etching has allowed the structure of the cytoplasm to be studied without the artefacts that might be introduced by fixation. (18 Nov 1997) |

| hippocratic face | Facies hippocratica, a pinched expression of the face, with sunken eyes, concavity of cheeks and temples, relaxed lips, and leaden complexion; observed in one close to death after severe and prolonged illness. Synonym: hippocratic face. (05 Mar 2000) |
| dish face | A facial malformation characterised by protuberant forehead, depressed nose and maxilla, and prominent chin. Synonym: dish face. (05 Mar 2000) |
| E face | In freeze fracture the plasma membrane cleaves between the acyl tails of membrane phospholipids, leaving a monolayer on each half of the specimen. The E face is the inner face of the outer lipid monolayer. From within the cell this is the view that you would have of the outer half of the plasma membrane if the inner layer could be removed. The complementary surface is the P face (the inner surface of the inner leaflet of the bilayer). E stands for ectoplasmic, P for protoplasmic: not terms that are in common usage! (18 Nov 1997) |
| transverse vein of face | <anatomy, vein> A tributary of the superficial temporal or retromandibular veins, anastomosing with the facial vein. Synonym: vena transversa faciei, transverse vein of face. (05 Mar 2000) |

| face-bow | <dentistry, equipment> A wire caliper-like device used to record the relationship of the jaws to the temporomandibular joints. The resulting record can then be used to create a cast or model of the maxilla to the opening and closing axis of the articulator. They consists of two metal parts attached together. The inner part is shaped like a horseshoe and is inserted in the mouth and connects to the buccal tubes. The outer part has two curves which go around the face, and connect to the headgear. An elastic neck band is placed around the back of the neck and attaches to the outer bow of the headgear. Completing the apparatus is a plastic safety strap that is placed over the neck band and onto the outer bow of the headgear. Synonym: hinge-bow, kinematic face-bow. (21 Jun 2000) |
