Process by which foreign particles are removed from a cell by phagosomes which engulf and digests the foreign body.
Cytoplasmic vesicle which engulfs foreign particles within a cell.
Process by which a cell engulfs droplets of fluid from its surroundings.
Selective cellular uptake of molecules that bind to a specific receptor.
Receptor mediated endocytosis
The process whereby part of the membrane is internalized and then reincorporated into the plasma membrane.
Vesicular processes that release material from a cell.
The combination of receptor-mediated endocytosis and exocytosis that moves particles through a cell.
Vesicular processes that bring matter into a cell.
The difference in electrical charge across a membrane.
A stable voltage across the plasma membrane of an unstimulated.
Resting membrane potential
A shift in electrical potential across a plasma membrane to a value more negative than the RMP, tendidng to inhibit a nerve or muscle cell.
A shift in electrical potential across a plasma membrane to a value less negative than the RMP, making a muscle or nerve cell easier to excite.
