Cellular Signaling

Cellular signaling is the process by which cells communicate to coordinate functions and respond to their environment. This involves signaling molecules, like hormones or neurotransmitters, binding to specific receptors on or inside the cell. This triggers a series of internal steps, called a signaling pathway, that lead to changes in cell behavior, such as growth, movement, or getting ready to respond to an external stimulus. These signals ensure that cells work together efficiently, adapt to changes, and maintain overall health and balance within the body.
