cell signaling
The document discusses cell signaling, defining it as the communication network between and within cells in the body that is facilitated by signaling molecules such as hormones. It elaborates on different types of signaling mechanisms, including paracrine, endocrine, autocrine signaling, and direct signaling across gap junctions, along with the roles of ligands and receptors in these processes. Additionally, it describes the steps involved in cell signaling: reception, transduction, and response, highlighting the importance of various ligands and receptors in mediating these signals.
