The ejection of cytoplasmic materials by the fusion of a membranous vesicle with the cell membrane.
The release of cellular substances (as secretory products) contained in cell vesicles by fusion of the vesicular membrane with the plasma membrane and subsequent release of the contents to the exterior of the cell
Process by which most molecules are secreted from a eucaryotic cell. These molecules are packaged in membrane-bounded vesicles that fuse with the plasma membrane, releasing their contents to the outside.
a process of discharging large cellular products; particles are enclosed by Golgi membranes when synthesized; vesicles pinch off from the Golgi complex & carry enclosed particles to the interior of the cell membrane; fusion occurs & contents are discharged
The fusion of an intracellular vesicle with the cell membrane and discharge of its contents to the exterior of the cell.
A process by which a vesicle within a cell fuses with the plasma membrane and releases its contents to the outside. (Contrast with endocytosis.)
Process by which molecules are secreted from the cell. Exocytosis occurs when a vesicle fuses with the cell membrane and releases its contents to the outside.
extrusion of substances from cells (e.g., mucus from bronchial epithelium).
The secretion or release of intracellular materials to the extracellular space.
is the release of intracellular vesicles (which contain neurotransmitter) by a process involving the docking and fusion of the vesicular membrane with the membrane of the cell. This is the mode of release of neurotransmitter at chemical synapses
(ehk'-so-sih-TO-sihs) The active cellular process by which materials are transported out of a cell and into the extracellular environment.
The process by which intracellular chemicals (including hormones) are released.
The cellular secretion of macromolecules by the fusion of vesicles with the plasma membrane.
EX-o-si-TOE-sis Fusing of secretion-containing organelles with the cell membrane. 93
Movement of materials from inside the cell to the outside by fusion of a vesicle with the membrane.
a process of cellular secretion or excretion in which substances contained in vesicles are discharged from the cell by fusion of the vesicular membrane with the outer cell membrane.
The process in which a membrane-enclosed vesicle Þrst fuses with the plasma membrane and then opens and releases its contents to the outside.
the process of discharge from a cell of particles too large to be secreted via cell-wall diffusion.
(EK-so-sye-TOE-sis) A process cells use to send substances outside their surface membrane via vesicles.
Random immigration of inflammatory cells through the epidermis, some cells reach the surface. This is common in inflammatory dermatoses. Eg. Spongiotic drug reaction.
Extrusion of vesicles from internal surface of membrane; can be induced by electrical or chemical agents. May contain transmitters or hormones, etc.
Process by which particles are moved from the cell to the exterior
Release of intracellular molecules (e.g., hormones, matrix proteins) contained within a membrane-bounded vesicle by fusion of the vesicle with the plasma membrane of a cell. This is the process whereby most molecules are secreted from eukaryotic cells. Opp. Endocytosis.
Exocytosis (ek-soh-sy-TOH-sis) is the process by which a cell releases large biomolecules through its membrane. While in protozoa (monocellular organisms) exocytosis may serve the function of eliminating waste products, in multicellular organisms exocytosis also has a role in signalling and regulatory functions. In multicellular organisms there are two types of exocytosis: 1) Ca2+ triggered non-constitutive and 2) non Ca2+ triggered constitutive.
