fusional m. a reflex m. that tends to move the visual axes to the object of fixation so that stereoscopic vision is possible.
hinge m. an opening or closing m. of the mandible on the hinge axis.
intermediary m.'s in dentistry, all m.'s between the extremes of mandibular excursions.
lateral m. in dentistry, m. of the mandible to the side.
Magnan's trombone m. an involuntary forward and back m. of the tongue when it is drawn out of the mouth; may be seen in several basal ganglia disorders.
mandibular m. 1. m.'s of the lower jaw; 2. all changes in position of which the mandible is capable.
mass m. mass peristalsis
molecular m. brownian m
morphogenetic m. the streaming of cells in the early embryo to form tissues or organs.
muscular m. m. caused by the contraction of the myofibrils of the muscle cells.
neurobiotactic m. the streaming of nerve cells toward the area from which they receive the most stimuli.
non-rapid eye m. (NREM) slow oscillation of the eyes during sleep.
opening m. in dentistry, m. of the mandible executed during jaw separation.
paradoxical m. of eyelids spontaneous, involuntary elevation or lowering of the eyelids, associated with m. of extraocular muscles or muscles of mastication (external pterygoids). See jaw winking.
passive m. m. imparted to an organism or any of its parts by external agency; m. of any joint effected by the hand of another person, or by mechanical means, without participation of the subject himself.
pendular m. a to-and-fro m. of the intestine, without any propelling or peristaltic action, whereby the contents are churned and thoroughly mixed with the intestinal ferments.
protoplasmic m. m. produced by the inherent power of contraction and relaxation of protoplasm; such m.'s are of three kinds: muscular, streaming, and ciliary.
rapid eye m.'s (REM) symmetrical quick scanning m.'s of the eyes occurring many times during sleep in clusters for 5 to 60 minutes; associated with dreaming.
