What's the difference between bulla and vesicle?

Bulla


Definition:

  • (20) The latter may have been related to the circumferential distribution of the bullae around each lung.

Vesicle


Definition:

  • (n.) A bladderlike vessel; a membranous cavity; a cyst; a cell.
  • (n.) A small bladderlike body in the substance of vegetable, or upon the surface of a leaf.
  • (n.) A small, and more or less circular, elevation of the cuticle, containing a clear watery fluid.
  • (n.) A cavity or sac, especially one filled with fluid; as, the umbilical vesicle.
  • (n.) A small convex hollow prominence on the surface of a shell or a coral.
  • (n.) A small cavity, nearly spherical in form, and usually of the size of a pea or smaller, such as are common in some volcanic rocks. They are produced by the liberation of watery vapor in the molten mass.

Example Sentences:

  • (1) 5-HT thus appears to be the preferred substrate for uptake into platelets and for movement from cytoplasm to vesicles.
  • (2) The predicted non-Lorentzian line shapes and widths were found to be in good agreement with experimental results, indicating that the local orientational order (called "packing" by many workers) in the bilayers of small vesicles and in multilamellar membranes is substantially the same.
  • (3) Reasonably good agreement is seen between theoretical apparent rate-vesicle concentration relationships and those measured experimentally.
  • (4) In normal seminal vesicle, the reaction product was apparently more abundant in columnar and basal cells than in other cell types.
  • (5) Freshly isolated sarcoplasmic reticulum vesicles contain 0.05 mol of tightly bound ADP and 0.03 mol of tightly bound ATP per mol of Ca2+, Mg2+-ATPase (ATP phosphohydrolase, EC 3.6.1.3).
  • (6) In contrast, in primordial follicles, FSH was restricted to the germ cell but was present in both the oocyte cytoplasm and germinal vesicle.
  • (7) In fact, the distribution of [3H]oleate between plasma membranes and unilamellar vesicles of lipids extracted from these membranes was in favor of the lipids, indicating the absence of a detectable amount of binding to a putative fatty acid binding protein in plasma membranes.
  • (8) This value may be compared to a Kd of 7.3 pM obtained by the same method for the interaction of DF-VIIa with TF1-263 reconstituted into phosphatidylcholine vesicles.
  • (9) This is interpreted to be a consequence of the adsorption of Ca2+ on the vesicle bilayers.
  • (10) The results suggest that AH5183 does not bind to the ACh transporter recognition site on the outside of the vesicle membrane, and thus it might inhibit allosterically.
  • (11) Although the brain AP50 is prominently phosphorylated by an endogenous protein kinase in isolated coated vesicle preparations, the neuronal AP50 was not detectably phosphorylated in intact cells as assessed by two-dimensional non-equilibrium pH gradient gel electrophoresis of labeled cells dissolved directly in SDS-containing buffers.
  • (12) Interaction of viable macrophages with cationic particles at 37 degrees C resulted in their "internalization" within vesicles and coated pits and a closer apposition between many segments of plasmalemma than with neutral or anionic substances.
  • (13) The toxins preferentially attenuate a slow phase of KCl-evoked glutamate release which may be associated with synaptic vesicle mobilization.
