Study Notes
Cell-to-Cell Communication
- Electrical communication involves changes in a cell's membrane potential.
Purpose of Cell-to-Cell Communication
- The purpose of cell-to-cell communication in the nervous system is to facilitate the transmission of information.
Methods of Cell-to-Cell Communication
- Ligand-protein interaction is a method of cell-to-cell communication that involves ligand binding to specific protein receptors on the surface of target cells.
Long-Distance Communication
- The purpose of long-distance communication in cell-to-cell communication is to enable the transmission of signals over longer distances, facilitating communication between distant cells and tissues.
