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.
Brownian movement (br u n - n)n. The random movement of microscopic particles suspended in a liquid or gas, caused by collisions with molecules of the surrounding medium. Also called Brownian motion, molecular movement, pedesis. |
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).
