Their historical association is reflected in their developmental interdependence and makes it difficult to describe the functional anatomy and evolution of one system without referring to the other.

Known as hormones, their production and secretion is often ultimately induced by environmental factors acting on the nervous system. Such factors include

Fertilization and Cleavage,and involves the complex behaviors associated with a species’ mating system. At the cellular level, it is the phenomenon by which an oocyte or ovum is mobilized to begin embryonic development. Fertilization is commonly thought to be the process by which male and female sex cells fuse. This commonly
