| systolic gradient | The difference in pressure during systole between two communicating cardiovascular chambers, e.g., between the left ventricle and aorta in aortic stenosis. (05 Mar 2000) |
| electrochemical gradient | A measure of the tendency of an ion to move passively from one point to another, taking into consideration the differences in its concentration and in the electrical potentials between the two points; commonly expressed as the additional voltage needed to achieve equilibrium. (05 Mar 2000) |
| ficoll gradient | A density gradient of ficoll (synthetic sucrose polymer) in solution, where concentration of the ficoll varies continuously through the solution. It is often used to separate different types of cells from each other during the process of sedimentation. (09 Oct 1997) |
| field gradient | In magnetic resonance imaging, a magnetic field that varies with location, superimposed on the uniform field of the magnet, to alter the resonant frequency of nuclei and allow recovery of their spatial position. Synonym: field gradient. (05 Mar 2000) |
| axial | <anatomy> Position as it relates to the CNS. Intra-axial is within the CNS, extra-axial is outside the CNS. (16 Dec 1997) |
| axial ametropia | That resulting from a shortening or lengthening of the eyeball on the optic axis, causing hyperopia or myopia, respectively. (05 Mar 2000) |
| axial aneurysm | An aneurysm involving the entire circumference of a blood vessel. (05 Mar 2000) |
| axial angle | An angle formed by two surfaces of a body, the line of union of which is parallel with its axis; the axial angle's of a tooth are the distobuccal, distolabial, distolingual, mesiobuccal, mesiolabial, and mesiolingual. (05 Mar 2000) |
| axial cataract | A lenticular opacity in the visual axis of the lens. (05 Mar 2000) |
| axial current | The central rapidly moving portion of the bloodstream in an artery. (05 Mar 2000) |
| axial filament | The central filament of a flagellum or cilium; with the electron microscope it is seen as a complex of nine peripheral diplomicrotubules and a central pair of microtubules. Synonym: axoneme. (05 Mar 2000) |

| axial muscle | <anatomy> One of the skeletal muscle's of the trunk or head. (05 Mar 2000) |
| axial neuritis | Inflammation of the nervous substance proper, the axons, and myelin. Synonym: axial neuritis, central neuritis. (05 Mar 2000) |
