Definition of vesicle in English: vesiclenoun ˈvɛsɪk(ə)lˈviːsɪk(ə)lˈvɛsək(ə)l 1Anatomy Zoology A small fluid-filled bladder, sac, cyst, or vacuole within the body. 〔剖,动〕囊,泡 Example sentencesExamples - Both vesicles and bilayer patches were found not to move laterally over the time range of 10 min and more, except at relatively high imaging forces.
- This process allows the vesicles to dock to that part of the membrane where the neurotransmitters are due to be released into the synapse (the active zone).
- They are united by the presence of small vesicles in, or just under, the plasma membrane.
- The two vesicles resemble small, bulbous pouches and are located just above the prostate gland.
- The prevailing model argues that specific proteins are shuttled around to their destinations, both within and outside the cell, in enclosed vesicles.
Synonyms bag, pouch, bladder, blister - 1.1Medicine A small blister full of clear fluid.
〔医〕小水疱 Example sentencesExamples - Infected animals excrete virus in exhaled air, in saliva, in milk, in semen, in faeces, in urine and in ruptured vesicle fluid.
- Chickenpox usually occurs in children, causing slight fever and an eruption of transparent vesicles (blisters).
- Skin infection begins as a raised itchy bump that resembles an insect bite but within one-two days develops into a vesicle and then a painless ulcer.
- In fact, she had beautiful skin apart from the scattered vesicles caused by the chicken pox.
- Several hours or days following exposure, affected skin in a previously sensitized individual becomes itchy and red and may develop small vesicles or blisters.
Synonyms bleb, bulla, pustule, vesication, blain
2Botany An air-filled swelling in a plant, especially a seaweed. 〔植〕(植物,尤指海藻的)小泡,泡囊 Example sentencesExamples - When resin vesicles are damaged during seed processing, the result is generally a decline in seed germination.
- Here we report that this defect formation is strongly enhanced by the membrane tension induced by osmotic swelling of vesicles.
- The properties of plasma membrane vesicles from wheat roots are also affected by deprivation of the intact plants.
- Plant vesicle trafficking will serve similar functions to those seen in animals and yeast.
- No significant differences were observed in the composition of vesicles isolated from nitrate-treated and control roots (not shown).
3Geology A small cavity in volcanic rock, produced by gas bubbles. 〔地质〕气泡 Example sentencesExamples - In the road cuts of both early and later construction, rock was blasted that contains zeolite-filled vesicles.
- A variety of minerals were deposited in the hollow vesicles.
- The gray bar in the middle of the image represents the virtual projection of spectrometer slit onto the vesicle.
- In some lavas, rising gas bubbles may stretch out to form tubular vesicles.
- Calcite, along with epidote, fills small vesicles in the basaltic dike rock.
Synonyms space, chamber, hollow, hole, pocket, pouch
Derivativesadjective vɪˈsɪkjʊləvəˈsɪkjələr On the basis of the vesicular structure of the shell wall, Fisher felt that they were not closely related to annelid worms. Example sentencesExamples - A three-year-old boy presented with a vesicular rash on the right flank and right buttock.
- Several observations on normal and injured lungs raise interest in the molecule and pathway specificity of deformation triggered vesicular trafficking.
- The thickest segments of the main tubes have a core of vesicular glass that is a terra-cotta color.
- In addition, vesicular release probability and the extent of spillover finely tune the concentration that distant receptors feel during trains of stimuli.
adjectivevɪˈsɪkjʊleɪtɪd The vesiculated nerve profiles were tentatively classified on the basis of the fine structural appearances of their vesicular content. Example sentencesExamples - The chromatin was clumped, giving the nuclei a clear vesiculated appearance.
- Others were highly vesiculated and contained discrete but degenerating organelles, such as nuclei and mitochondria.
- To address this issue, we have studied microstructure of vesiculated crystal mush experimentally.
- Seismically, vesiculated zones exhibit low compressional-wave velocities.
noun vɪˌsɪkjʊˈleɪʃ(ə)nvəˌsɪkjəˈleɪʃ(ə)n These properties contribute to curvature stress that promotes hexagonal phase formation and membrane trafficking through vesiculation and fusion. Example sentencesExamples - The identity and source of the vapor phase that caused lunar lava-fountaining and vesiculation in lunar basalts continues to be of interest because of its implications for the composition and state of the lunar interior and because of its implications for lunar resources.
- Ancillary calculations have established the net heat effect of the prescribed ascent path and demonstrate that the heat associated with vesiculation easily compensates for the heats of crystallization.
- The sloughed area is caused by vesiculation and it in turn has many etiologies including thermal and chemical burns, exfoliative dermatitis secondary to a drug reaction, bacterial and fungal infections.
- Particular attention was paid to the description of each part of the stratigraphy, noting features such as degree of vesiculation, fracturing, weathering style, lithology and texture.
OriginLate 16th century: from French vésicule or Latin vesicula, diminutive of vesica 'bladder'.
