The following is a list of hormones found in Homo sapiens.Spelling is not uniform for many hormones. For example, current North American and international usage uses [citation needed] estrogen and gonadotropin, while British usage retains the Greek digraph in oestrogen and favours the earlier spelling gonadotrophin.
Anatomical terminology. [edit on Wikidata] The endocrine system[1] is a messenger system in an organism comprising feedback loops of hormones that are released by internal glands directly into the circulatory system and that target and regulate distant organs. In vertebrates, the hypothalamus is the neural control center for all endocrine systems.

Hormone transport and the involvement of binding proteins is an essential aspect when considering the function of hormones. [48] This is a diagram that represents and describer what hormones are and their activity in the bloodstream. Hormones flow in and out of the bloodstream and are able to bind to Target cells to activate the role of the ...
Endocrinology (from endocrine + -ology) is a branch of biology and medicine dealing with the endocrine system, its diseases, and its specific secretions known as hormones.It is also concerned with the integration of developmental events proliferation, growth, and differentiation, and the psychological or behavioral activities of metabolism, growth and development, tissue function, sleep ...

A neurohormone is any hormone produced and released by neuroendocrine cells (also called neurosecretory cells) into the blood. [1][2] 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 such as autocrine (self) or paracrine (local) messenger.
Local hormones are produced by nerve and gland cells and bind to either neighboring cells or the same type of cell that produced them. Local hormones are activated and inactivated quickly. [1] They are released during physical work and exercise. They mainly control smooth and vascular muscle dilation. [2]
