If the lateral movement is constrained, for instance, burying pipe or dumping gravel, upheaval buckling may happen.
If we assume that the body's movement is constrained in a fixed interaction space, so that a specific motion with certain semantics is composed of an infrared sequence of moving body parts.
When phagosome movement is constrained, this mechanism fails, and exocytosis soon follows.
Thus, cell division and movement are constrained by available space.
More recently, mitochondrial fusion and fission proteins have been investigated in the adult heart, in which mitochondria have a distinct arrangement and in which mitochondrial movement is constrained by the cellular architecture.
We should keep in mind that individual epithelial movement in a crowded situation is determined by relative movement of the surrounding cells because their movement is constrained through intercellular adhesion that triggers mechanical mutual interaction between neighboring cells rather than interfacial contact alone.
Carnivora and Dasyuromorphia are good systems for comparing hypotheses about similarities in tooth shape and movement during occlusion because of ecological similarities, gross morphological differences and because mandibular movement is constrained to being only rotation and mediolateral translation with extremely limited anteroposterior movement.
Analysis of Group II particles in 2D by Maskiton (Yoshioka et al., 2013) recapitulates this result and additionally indicates that head movement is constrained by a short but highly flexible linker (Video 2), likely comprising the 3′-end of helix 27 and the 3′-strand of the unformed h2 (16S residues 910 919).
During play, his head movements are constrained, at least in contrast to the on-screen action.
