movement /move·ment/ (mldbomacv´ment)
1. an act of changing position. 2. defecation. ameboid movement movement like that of an ameba, accomplished by protrusion of cytoplasm of the cell. associated movement 1. movement of parts which act together, as the eyes. 2. synkinesis. bowel movement defecation (def. 2). brownian movement the random zigzag or dancing movement of minute solute particles suspended in a solvent, due to bombardment by rapidly moving solvent molecules. rapid eye movement (REM) the rapid conjugate movement of the eyes that occurs during REM sleep (see under sleep ). vermicular movement peristalsis.
ameboid movement [əmē′boid] Etymology: Gk, amoibe, ameba, eidos, form; L, movere, to move the ameba-like movement of certain types of body cells that can migrate through tissues, such as leukocytes. The movement generally consists of extension of a portion of the plasma membrane, probably caused by internal rearrangement or movement of the cytoskeleton. See also diapedesis. movement [mo̳v´ment] 1. an act of moving; called also motion. 2. an act of defecation. active movement movement produced by the person's own muscles. ameboid movement movement like that of an ameba, accomplished by protrusion of cytoplasm of the cell. associated movement movement of parts that act together, as the eyes. brownian movement the peculiar, rapid, oscillatory movement of fine particles suspended in a fluid medium; called also molecular movement. circus movement the propagation of an impulse again and again through tissue already previously activated by it; the term is usually reserved for the reentry involving an accessory pathway. molecular movement brownian movement. passive movement a movement of the body or of the extremities of a patient performed by another person without voluntary motion on the part of the patient. vermicular m's the wormlike movements of the intestines in peristalsis.
movement an act of moving; motion. movement abnormality includes involuntary movement, lack of flexion or rigidity, hyper- or hypometric. active movement movement produced by the animal's own muscles. ameboid movement movement like that of an ameba, accomplished by protrusion of cytoplasm of the cell. associated movement movement of parts that act together, such as the eyes. brownian movement continuous movement of particles suspended within a liquid. conjugate movement two parts moving synchronously in the same direction, e.g. the eyes. disjunctive movement two parts moving synchronously but in opposite directions. involuntary movement a movement which the animal is unable to prevent. molecular movement the peculiar, rapid, oscillatory movement of fine particles suspended in a fluid medium. passive movement a movement of the body or of the extremities of an animal performed by a person without voluntary motion on the part of the animal. purposeful movement see voluntary movement (below). vermicular m's the wormlike movements of the intestines in peristalsis. voluntary movement performed out of the will of the animal; an intentional purposeful movement.
