Ans. C i.e. OxytocinNeurohormoneIt is any hormone produced and released by neuroendocrine cells (also called neurosecretory cells) into the blood.By definition of being hormones, they are secreted into the circulation for systemic effect, but they can also have a role of neurotransmitter or other roles as autocrine (self) or paracrine (local) messenger.The hypothalamus produces the hypophysiotropic and neurohypophysial hormones in specialized hypothalamic neurons which extend to the median eminence and posterior pituitary.The adrenal medulla produces adrenomedullary hormones in chromaffin cells, cells which are very similar in structure to post-synaptic sympathetic neurons, even though they are not neurons they are derivatives of the neural crest.Enterochromaffin and enterochromaffin-like cells, both being enteroendocrine cells, are also considered neuroendocrine cells due to their structural and functional similarity to chromaffin cells, although they are not derivatives of the neural crest.
