ves•i•cleˈvɛs ɪ kəl(n.)
a small sac, cyst, or cavity, esp. one filled with fluid.
Category: Anatomy, Biology
Ref: blister (def. 1). 1
a small, spherical cavity in a rock or mineral, formed by expansion of a gas before the enclosing body solidified.
Origin of vesicle:
1570–80; < L vēsīcula little bladder. See vesica , -ule
a small anatomically normal sac or bladderlike structure (especially one containing fluid)
A membrane-bound compartment found in a cell.
A small bladder-like cell or cavity.
A small sac or cyst or vacuole, especially one containing fluid. A blister formed in or beneath the skin, containing serum. A bleb.
A pocket of embryonic tissue that is the beginning of an organ.
A small cavity formed in volcanic rock by entrapment of a gas bubble during solidification.
Origin: From vésicule or its source, vesicula.
a bladderlike vessel; a membranous cavity; a cyst; a cell
a small bladderlike body in the substance of vegetable, or upon the surface of a leaf
a small, and more or less circular, elevation of the cuticle, containing a clear watery fluid
a cavity or sac, especially one filled with fluid; as, the umbilical vesicle
a small convex hollow prominence on the surface of a shell or a coral
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
In cell biology, a vesicle is a small bubble within a cell, and thus a type of organelle. Enclosed by lipid bilayer, vesicles can form naturally, for example, during endocytosis. Alternatively, they may be prepared artificially, when they are called liposomes. If there is only one phospholipid bilayer, they are called unilamellar vesicles; otherwise they are called multilamellar. The membrane enclosing the vesicle is similar to that of the plasma membrane, and vesicles can fuse with the plasma membrane to release their contents outside of the cell. Vesicles can also fuse with other organelles within the cell. Vesicles perform a variety of functions. Because it is separated from the cytosol, the inside of the vesicle can be made to be different from the cytosolic environment. For this reason, vesicles are a basic tool used by the cell for organizing cellular substances. Vesicles are involved in metabolism, transport, buoyancy control, and enzyme storage. They can also act as chemical reaction chambers.
