Communication by extracellular signals usually involves six steps: (1) synthesis and (2) release of the signaling molecule by the signaling cell; (3) transport of the signal to the target cell; (4) detection of the signal by a specific receptor protein; (5) a change in cellular metabolism, function, or development triggered by the receptor-signal ...What is cell signaling?
Cell signaling is the process of cellular communication within the body driven by cells releasing and receiving hormones and other signaling molecules. As a process, cell signaling refers to a vast network of communication between, and within, each cell of our body. Cell signaling enables coordination within multicellular organisms.What is an example of endocrine signaling?
Growth hormone (GH) is a great example. The pituitary gland releases this hormone, which stimulates growth in cells, cartilage, and bones. In this example of endocrine signaling, GH leaves the pituitary gland and travels through the blood stream to the cells throughout the body.
