| symphysis intervertebralis | The union between adjacent vertebral bodies composed of the nucleus pulposus, annular ligament, and the anterior and posterior longitudinal ligaments. Synonym: symphysis intervertebralis. (05 Mar 2000) |
| symphysis mandibulae | The fibrocartilaginous union of the two halves of the mandible in the foetus; it becomes an osseous union during the first year. Synonym: symphysis mandibulae, symphysis mentalis, symphysis menti. (05 Mar 2000) |
| symphysis manubriosternalis | The later union, by fibrocartilage, of the manubrium and the body of the sternum; it begins as a synchondrosis and becomes a symphysis, occasionally fusing to become a synostosis. Synonym: symphysis manubriosternalis, sternomanubrial junction. (05 Mar 2000) |
| symphysis mentalis | The fibrocartilaginous union of the two halves of the mandible in the foetus; it becomes an osseous union during the first year. Synonym: symphysis mandibulae, symphysis mentalis, symphysis menti. (05 Mar 2000) |
| symphysis menti | The fibrocartilaginous union of the two halves of the mandible in the foetus; it becomes an osseous union during the first year. Synonym: symphysis mandibulae, symphysis mentalis, symphysis menti. (05 Mar 2000) |
| symphysis pubica | The joint between the pubic bones at the front of the pelvis. (12 Dec 1998) |
| symphysis pubis | The Greek word symphysis means growing together. The pubis are the pubic bone. So the symphysis pubis is where the pubic bones meet (in the front of the pelvis). (12 Dec 1998) |

| sympiesometer | A sensitive kind of barometer, in which the pressure of the atmosphere, acting upon a liquid, as oil, in the lower portion of the instrument, compresses an elastic gas in the upper part. The column of oil of a lower part BC of a glass tube compresses hydrogen gas in the upper part AB, and is thus measured on the scale pq by the position of a surface of the oil in the tube. The scale pq is adjustable, and its index must be set to the division on the scale rs corresponding to the temperature indicated by the termometer t, in order to correct for the effects of temperature on the gas. It is sensitive, and convenient for use at sea, but inferior in accuracy to the mercurial barometer. Origin: Gr. Compression (fr. To press together; with + to press, squeeze).
