Medical Definition of Brownian movement
1. 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)
