I focused on explaining “how the endocrine system and nervous interact with each other”. I did this by exploring neuroendocrine tumors. Neuroendocrine tumors or NETS is a classification of rare tumors called neuroendocrine neoplasms—the heterogeneous tumor affects neuroendocrine cells meaning endocrine cells connected to the nervous system (Oronsky, Ma, Morgensztern, & Carter, 2017). Neuroendocrine cells are similar to nerve cells and hormone-producing cells in traits (Neuroendocrine tumors, 2023). The neuroendocrine system is responsible for transporting information, regulating metabolic functions, and controlling the interaction between the body’s organs (NeuroEndocrine Cancer Australia, 2022). Neuroendocrine cells make hormones like endocrine cells, receive signals like nerve cells, and release hormones (NeuroEndocrine Cancer Australia, 2022).
