Germinal vesicle
[L. germinis - bud, offshoot; L. vesicula- bladder]. The greatly enlarged nucleus of an oocyte.
The GTPase dynamin I is essential for synaptic vesicle endocytosis in nerve terminals.
membrane-bound organelle in the head of a sperm that is derived from the golgi apparatus; the vesicle containing enzymes that digest proteins and complex sugars in the outer coverings of an egg.
vesicles Small membrane-bound spaces in most plant and animal cells that transport macromolecules into and out of the cell and carry materials between organelles in the cell.
vesicle
[L. vesicula, a little bladder]
A small, intracellular membrane-bound sac.

Vesicles are small sacs that pinch off the endoplasmic reticulum or Golgi apparatus (discussed below) and transport molecules to other parts of the cell.
Smooth Endoplasmic Reticulum ...
Vesicle (VEH-sih-kle) A small, membrane-bounded sac that transports substances between organelles as well as to and from the cell membrane.
seminal vesicles Glands that contribute fructose to sperm. The fructose serves as an energy source. The structures that add fructose and hormones to semen. PICTURE ...
seminal vesicles
Apart of the male reproductive tract that stores sperm in invertebrates and produces semen in vertebrates.
seminiferous tubules
Highly coiled tubes in the testes in which sperm are produced.
vesicles Membrane-bound particles pinched off by constriction of a membrane, as in the Golgi apparatus.
vesicular disease Any disease of the urinary bladder, such as vesicular schistosomiasis.
The vesicles of the thyroid of the adult animal are generally closed spherical sacs; but in some young animals, e. g., young dogs, the vesicles are more or less tubular and branched.
the vesicles make a brief contact at the plasma membrane,
release their contents (neurotransmitters in this case) to the exterior, and
then retreat back into the cytosol.
Synaptic Vesicles
Synaptic vesicles fuse with the presynaptic membrane, freeing neurotransmitter molecules into the synaptic space.

Secretory Vesicle: Cell secretions - e.g. hormones, neurotransmitters - are packaged in secretory vesicles at the Golgi apparatus. The secretory vesicles are then transported to the cell surface for release.

Foundation of Vesicles
The Golgi complex gathers simple molecules and combines them to make molecules that are more complex.
An organism whose cells possess a nucleus and other membrane-bound vesicles, including all members of the protist, fungi, plant and animal kingdoms; and excluding viruses, bacteria, and blue-green algae. See Prokaryote. Evolution.
Most proteins exported from the endoplasmic reticulum exit the organelle in vesicles budded from the smooth portion, ...
Some of them are tubules, and some of them are vesicles. The Golgi is located right near the nucleus. It's called a perinuclear body, and it's actually right near the endoplasmic reticulum as well.
Vesicle movement between organelles and the cell surface, frequently studied in the squid axon.
Cytoplasmic streaming
Movement of pigment vesicles for protective coloration
Discharge of vesicle content for water regulation in protozoa ...
Both insulin and digestive enzymes are made in the RER and modified and packaged into vesicles in the Golgi apparatus. These vesicles are released by the cell by a process known as exocytosis.

Liposomes. Membrane-bound vesicles constructed in the laboratory to transport biological molecules.
Locus (plural = loci). A specific location or site on a chromosome.
Log phase. See Logarithmic phase.
liposomes - synthetic bilayer in the form of a spherical vesicle
membrane potential - voltage difference across a membrane due to a slight excess of positive ions on one side and of negative ions on the other ...
Liposomes Lipid vesicles having an aqueous region enclosed by a lipid bilayer
Long terminal repeat A sequence that is repeated at either end of a retroviral DNA molecule.
The second is the differentiation of an elaborate system of intracytoplasmic membrane vesicles when cells run out of oxygen and are placed in light. The membranes are used to house photosynthetic pigments and associated proteins.
