| basibregmatic axis | A line extending from the basion to the bregma. (05 Mar 2000) |
|---|---|
| basicranial axis | A line drawn from the basion to the midpoint of the sphenoethmoidal suture. (05 Mar 2000) |
| basifacial axis | A line drawn from the subnasal point to the midpoint of the sphenoethmoidal suture. Synonym: facial axis. (05 Mar 2000) |
| biauricular axis | A straight line joining the two auricles. Compare: auriculare. (05 Mar 2000) |
| magnetic axis | <physics> This typically refers to the location of the innermost flux surface in a toroidal device, the one which encloses no volume and has therefore degenerated from a flux surface into a single field line. Roughly, the circle through the middle of the dough of the donut. Additionally, in systems with magnetic islands (see entry below), each island has a local magnetic axis, distinct from the overall magnetic axis of the torus. (09 Oct 1997) |
| mandibular axis | An imaginary line around which the mandible may rotate through the horizontal plane. Synonym: hinge axis, mandibular axis. (05 Mar 2000) |
| vertical axis | In dentistry, the line around which the working side condyle rotates in the horizontal plane during mandibular movement. (05 Mar 2000) |
| mean electrical axis | The average magnitude and direction of all the electromotive forces developed during the cardiac event under consideration; e.g., atrial or ventricular depolarisation, or ventricular repolarization. See: axis deviation. (05 Mar 2000) |
| visual axis | The straight line extending from the object seen, through the centre of the pupil, to the macula lutea of the retina. Synonym: line of vision. (05 Mar 2000) |
| cephalocaudal axis | cephalocaudal axis |
| pelvic axis | A hypothetical curved line joining the centre point of each of the four planes of the pelvis, marking the centre of the pelvic cavity at every level. Synonym: axis pelvis, plane of pelvic canal. (05 Mar 2000) |
| cerebrospinal axis | The central nervous system; the brain and spinal cord. Synonym: encephalomyelonic axis, neural axis. (05 Mar 2000) |
| right axis deviation | A mean electrical axis of the heart pointing to the right of +90 |
| rotational axis | An imaginary line around which a removable partial denture tends to rotate. Synonym: rotational axis. (05 Mar 2000) |
| coeliac axis | Origin, abdominal aorta just below diaphragm; branches, left gastric, common hepatic, splenic. Synonym: truncus coeliacus, arteria coeliaca, coeliac artery, coeliac axis, Haller's tripod. (05 Mar 2000) |
