| cephalic pole | The head end of the foetus. (05 Mar 2000) |
| cephalic presentation | Presentation of any part of the foetal head, usually the upper and back part as a result of flexion such that the chin is in contact with the thorax in vertex presentation; there may be degrees of flexion so that the presenting part is the large fontanel in sincipital presentation, the brow in brow presentation, or the face in face presentation. Synonym: head presentation. (05 Mar 2000) |
| cephalic reflexes | Reflex's associated with the cranial nerves. (05 Mar 2000) |
| cephalic tetanus | A type of local tetanus that follows wounds to the face and head; after a brief incubation (1-2 days) the facial and ocular muscles become paretic yet undergo repeated tetanic spasms. The throat and tongue muscles may also be affected. Synonym: cerebral tetanus, head tetanus, hydrophobic tetanus, rose cephalic tetanus, Rose's cephalic tetanus. (05 Mar 2000) |
| cephalic triangle | A triangle on the cranium formed by lines connecting the metopion, the pogonion, and the occipital point. (05 Mar 2000) |
| cephalic vein | <anatomy, vein> Arises at the radial border of the dorsal venous rete of the hand, passes upward in front of the elbow and along the lateral side of the arm; it empties into the upper part of the axillary vein. Synonym: vena cephalica. (05 Mar 2000) |
| cephalic version | Version in which the foetus is turned so that the head presents; can be external cephalic version or internal cephalic version. See: external cephalic version, internal cephalic version. (05 Mar 2000) |
| cephalin | A term formerly applied to a group of phosphatidic esters resembling lecithin but containing either 2-ethanolamine or l-serine in the place of choline; these are now known as phosphatidylethanolamine and phosphatidylserine.

| cephaline | Denoting members of the protozoan suborder Cephalina (order Eugregarinida), characterised by bodies divided into chambers (anterior protomerite and posterior deutomerite, or anterior epimerite, protomerite, and terminal deutomerite); all are parasites of invertebrates. (05 Mar 2000) |
