Uropod
Definition:
(n.) Any one of the abdominal appendages of a crustacean, especially one of the posterior ones, which are often larger than the rest, and different in structure, and are used chiefly in locomotion. See Illust. of Crustacea, and Stomapoda.
Example Sentences:
(1) The label was present in a spotty fashion or over a so-called uropod.
(2) Upon further incubation at 37 degrees C, Con A was internalized over the entire cell periphery of the rounded, untreated cells but on collagenase-treated PMNs was rapidly gathered into a cap overlying the uropod or protuberant region of cytoplasm where it was subsequently internalized.
(3) The most simple macrophage-lymphocyte cluster consisted of one macrophage, one large central lymphocyte with a blastoid appearance attached to the macrophage with a broad area of contact, and from a few to more than 20 small peripheral lymphocytes attached to the central lymphocyte by their uropods.
(4) During cell locomotion the fluorescent labels redistribute to the uropod and retraction fibers.
(5) Some lymphocytes with smooth surface showing uropods were also observed.
(6) Both flattening and elongation of the adherent cells are inhibited by low temperature, chelating agents, cytochalasin B, and vinblastine, while sodium azide selectively inhibits elongation and uropod formation.
(7) Analyses of electromyograms of untrestrained Emerita, before and after bilateral surgical ablation of the four nonspiking mechanoreceptive cells associated with each uropod, established that power strokes in 'treading water' are dependent upon proprioceptive feedback from the nonspiking cells.
(8) CF bound to the plasma membrane and was internalized on the membranes of vesicles and vacuoles, a process that was particularly prominent at the uropod of basophils exhibiting a polarized ('motile') configuration.
