| saltatory movement | Abrupt jumping movements of the sort shown by some intracellular particles. Mechanism unclear. (18 Nov 1997) |
|---|---|
| protoplasmic movement | Movement produced by the inherent power of contraction and relaxation of protoplasm; such movement's are of three kinds: muscular, streaming, and ciliary. (05 Mar 2000) |
| hinge movement | An opening or closing movement of the mandible on the hinge axis. (05 Mar 2000) |
| sham-movement vertigo | Dizziness accompanied by an impression that the body is rotating or that objects are rotating about the body. Synonym: gyrosa. (05 Mar 2000) |
| stereotypic movement disorder | Motor behaviour that is repetive, often seemingly driven, and nonfunctional. This behaviour markedly interfers with normal activities or results in severe bodily self-injury. The behaviour is not due to the direct physiological effects of a substance or a general medical condition. (dsm-IV, 1994) (12 Dec 1998) |
| neurobiotactic movement | The streaming of nerve cells toward the area from which they receive the most stimuli. (05 Mar 2000) |
| streaming movement | The form of movement characteristic of the protoplasm of leukocytes, amoebae, and other unicellular organisms; it involves the massing of the protoplasm at a point where surface pressure is least and its extrusion in the form of a pseudopod; the protoplasm may return to the body of the cell, resulting in the retraction of the pseudopod, or the entire mass may flow into the latter and thereby result in locomotion of the cell. (05 Mar 2000) |
| decomposition of movement | A manifestation of cerebellar disease in which a muscular movement is not carried out smoothly but in a series of component motions. (05 Mar 2000) |
| disconjugate movement of eyes | Rotation of the two eyes in opposite directions, as in convergence or divergence. (05 Mar 2000) |
| illusion of movement | Successive stimulation of neighboring retinal points which causes the sensation of movement. Oculogravic illusion, apparent movement of the visual field when the body is subjected to acceleration; due to gravity. Oculogyral illusion, an illusion occurring in angular acceleration in which the position of fixed light appears to drift. Optical illusion, a false interpretation of the colour, form, size, or movement of a visual sensation. (05 Mar 2000) |
| opening movement | In dentistry, movement of the mandible executed during jaw separation. (05 Mar 2000) |
| tooth movement | Orthodontic techniques used to correct the malposition of a single tooth. (12 Dec 1998) |
| translatory movement | The motion of the body at any instant when all points within the body are moving at the same velocity and in the same direction. (05 Mar 2000) |
| fixational ocular movement | Rotation of the eyes during voluntary fixation on an object; tremors, flicks, and drifts occur. (05 Mar 2000) |
| foetal movement | <obstetrics> Movement of the foetus in the womb perceived by the mother and felt by palpation of the abdomen. The first foetal movements felt by the mother during pregnancy (quickening) are usually between18 and 22 weeks of pregnancy. (08 Mar 2000) |
