| ciliary movement | The rhythmic, sweeping movement of epithelial cell cilia, of ciliate protozoans, or the sculling movement of flagella, effected possibly by the alternate contraction and relaxation of contractile threads (myoids) on one side of the cilium or flagellum. (05 Mar 2000) |

| circus movement | A contraction or excitation wave traveling continuously in circular fashion around a ring of muscle or through the wall of the heart. Synonym: circus rhythm. (05 Mar 2000) |
| molecular movement | Erratic, nondirectional, zigzag movement observed by ultramicroscope in certain colloidal solutions and by microscope in suspensions of light particulate matter that results from the jostling or bumping of the larger particles by the molecules in the suspending medium which are regarded as being in continuous motion. Synonym: brownian motion, brownian-Zsigmondy movement, molecular movement, pedesis. (05 Mar 2000) |
| morphogenetic movement | <embryology> Movements of cells or of groups of cells in the course of development. Thus the invagination of cells in gastrulation is one of the most dramatic of morphogenetic movements, another much studied example is the migration of neural crest cells. (21 Jun 2000) |
| movement | 1. The act of moving; change of place or posture; transference, by any means, from one situation to another; natural or appropriate motion; progress; advancement; as, the movement of an army in marching or manoeuvreing; the movement of a wheel or a machine; the party of movement. 2. Motion of the mind or feelings; emotion. 3. Manner or style of moving; as, a slow, or quick, or sudden, movement. 4. The rhythmical progression, pace, and tempo of a piece. "Any change of time is a change of movement." . One of the several strains or pieces, each complete in itself, with its own time and rhythm, which make up a larger work; as, the several movements of a suite or a symphony. 5. <mechanics> A system of mechanism for transmitting motion of a definite character, or for transforming motion; as, the wheelwork of a watch. <medicine> Febrille movement See Kinesiatrics. Movement of the bowels, an evacuation or stool; a passage or discharge. Synonym: Motion. Movement, Motion. Motion expresses a general idea of not being at rest; movement is oftener used to express a definite, regulated motion, especially. A progress. Origin: F. Mouvement. See Move, and cf. Moment.

| movement-related pain | <symptom> A type of breakthrough pain that is related to specific activity, such as eating, defecation, socialising or walking. Also referred to as incident pain. (16 Dec 1997) |
| contact inhibition of movement | Reaction in which the direction of motion of a cell is altered following collision with another cell. In heterologous contacts both cell may respond (mutual inhibition) or only one (nonreciprocal). Type I contact inhibition involves paralysis of the locomotory machinery, Type II is a consequence of adhesive preference for the substratum rather than the dorsal surface of the other cell. (18 Nov 1997) |
| muscular movement | Movement caused by the contraction of the myofibrils of the muscle cells. (05 Mar 2000) |
| saccadic movement | A quick rotation of the eyes from one fixation point to another as in reading, the rapid correction movement of a jerky nystagmus, as in labyrinthine and optokinetic nystagmus. (05 Mar 2000) |
| 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) |
