In animals, hormones are produced by the neurosecretory neurons. They regulate the processes of reproduction, development, and growth of some of the features of the body. They also regulate the sugar levels, heart rate, water balance, and reproduction in annelids, arthropods, and mollusks. Certain hormones are related in invertebrates and vertebrates.
