Phagosome
Process by which a cell engulfs droplets of fluid from its surroundings.
Pinocytosis
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.
Membrane recycling
Vesicular processes that release material from a cell.
Exocytosis
The combination of receptor-mediated endocytosis and exocytosis that moves particles through a cell.
Transcytosis
Vesicular processes that bring matter into a cell.
Endocytosis
The difference in electrical charge across a membrane.
Electrical gradient
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.
Hyperpolarization
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.
