The hormones that are produced and released by neuroendocrine cells into the blood stream are known as neurohormones. The neuroendocrine cells are also known as neurosecretory cells. By definition of being hormones, these are secreted into the blood for general effects, but these Neurohormones can also have other functions as neurotransmitter or as self-messenger i.e, autocrine messenger or local messengers i.e, paracrine messenger. In specialized hypothalamic neurons the hypothalamus produces neurohypophysial hormones as well as releasing hormones which extend to the median eminence and neurohypophysis.
The adreno-medullary hormones are produced in chromaffin cells, cells that are similar in structure to post-synaptic sympathetic neurons, by adrenal medulla. Even if they are not neurons they are derivatives of the neural crest. Releasing hormones also known as hypophysiotropic or hypothalamic hormones are synthesized by different kinds of specialized neurons in the hypothalamus. Journal of Steroids & Hormonal Science is an official journal of OMICS Group International that publishes all the topics that are covered under Neurohormones.
