Neuro hormones
Neuro hormones, refers to any of a group of substances produced by the neuroendocrine cells, (also known as the neurosecretory cells) and is released in the blood stream, they are structurally typical of the nervous system, rather than of the endocrine system. The neuro hormones pass along nerve-cell extensions (axons) and are released into the bloodstream at certain special regions called neurohemal organs. Neurohormones thus can be considered to be a connection between sensory stimuli (events or conditions perceived by the central and peripheral nervous system) and chemical responses i.e the hormones (endocrine secretions which acts on other tissues of the endocrine system or on tissues of other systems, like the one involved with excretion or reproduction). Besides the hormones of the endocrine glands, these hormones also regulate behavior. The important neuro hormones are as follows:
- thyrotropin-releasing hormone.
- Growth hormone-releasing hormone.
- Corticotrophin-releasing hormone.
- Somatostatin.
- Gonadotropin-releasing hormone.
- Neurotensin.
- Dopamine.
