Question

Explain the differences between endocrine and neuroendocrine signal transmission using both vertebrate and invertebrate examples.

Answer 1

The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things.

The neuroendocrine system is the mechanism by which the hypothalamus maintains homeostasis, regulating reproduction, metabolism, eating and drinking behaviour, energy utilization, osmolarity and blood pressure.

Invertebrate endocrine systems are composed primarily of neuroendocrine components, with fewer true glands than are present in the vertebrates.

Neuroendocrine signaling : A type of cell signaling involving the release of a hormone from a nerve cell that has an effect on another cell.
