Cells communicate with each other through a process known as cell signaling. This involves the release of signaling molecules such as hormones and neurotransmitters that bind to specific receptors on target cells, triggering a response. Cell signaling is vital for numerous biological processes, including development, immune response, and homeostasis. Through these signaling pathways, cells can coordinate activities, respond to changes in their environment, and maintain proper function, showcasing the intricacy of cellular interactions.
