exocytosis

 [ek″so-si-to´sis]
1. the discharge from a cell of particles that are too large to diffuse through the wall; the opposite of endocytosis.
2. the aggregation of migrating leukocytes in the epidermis as part of the inflammatory response.

ex·o·cy·to·sis

(ek'sō-sī-to'sis),
1. The appearance of migrating inflammatory cells in the epidermis.
2. The process whereby secretory granules or droplets are released from a cell; the membrane around the granule fuses with the cell membrane, which ruptures, and the secretion is discharged. Synonym(s): emeiocytosis, emiocytosis Compare: endocytosis.

exocytosis

The movement of peptides or proteins out of a cell into the extracellular fluid, in tiny membranous vesicles that pass through the plasma membrane.

exocytosis

an active process in which vesicles containing excretory or secretory materials are actively carried to the periphery of the cell, and released to the outside when the vesicle membrane fuses with the cell membrane. Compare ENDOCYTOSIS. See PHAGOCYTOSIS, PINOCYTOSIS.
