(n.) The internal or principal branch of the locomotive appendages of Crustacea. See Maxilliped.
Example Sentences:
(1) While an experimentally generated discontinuity between the lateral margin of the exopodite and the medial margin of the endopodite (outer-to-outer junction) triggers intercalation of supernumerary rami, a discontinuity of pattern between the medial margin of the exopodite and the lateral margin of the endopodite (inner-to-inner junction) is stable despite the absence of intervening intersegmental membrane.
(2) The branchial warts on the endopodites of the gills are covered with goblet-shaped cuticular appendages, whose internal structure shows them to be chemoreceptors.
(3) The endopodite of the male swimmeret has an accessory lobe covered with short "bristly spines" (serrate setae).
(4) The most caudal limb in crayfish, the uropod, has two rami, the exopodite and the endopodite.
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.
(9) Small fluctuations in their membrane potentials cause sustained change in activity of the motoneurons innervating the uropod muscles.
(10) Some cells were more irregular in shape, while others displayed clusters of polarized microvilli and small uropods.
(11) The results suggest a flow of CR3 from intracellular granules----lamellipodia and cell body----uropod----trailing filopodia during chemotaxis.
(12) We concluded that the continuous excitation of uropod motor neurons during the fictive abdominal movement was mediated, at least partly, by the local nonspiking interneurons.
(13) The results of all of our experiments on the uropod indicate that a conjunction of separate proximodistal, dorsoventral, and mediolateral component fields may give positional information for generating the uropod.
(14) When the animal was engaged in abdominal postural movement, all uropod motoneurons received sustained excitatory input.
(15) Uropod formation and inhomogeneous distribution were inhibited or reversed by cytochalasin B, but not by vinblastine or colchicine.
(16) The cap had a characteristic uropod form, enriched with intracellular organelles.
(17) Ultrastructural analyses showed, exclusively in delta-TCS1+ cells, nuclear deformations, uropod formation, and abundant cytoskeletal structures.
(18) On the contrary, on cells which had formed a uropod the labeled receptors and antigens appeared to be preferentially concentrated around the nucleus, and depleted over the uropod, and especially over the constriction at the base of the uropod.
(19) On the first and second days the transformation of lymphocytes into active cells with uropods is observed.
(20) In contrast, viruses were noted on the tip of the mouse HMC uropod by transmission electron microscopy.
