Certain and peripheral neuropeptides as signaling neurotransmitters

Nervous human neurotransmitters are necessary for sending nerve signals in the whole body in humans. Neuropeptides are small proteinaceous substances produced and released by neurons through the regulated secretory route and acting on neural substrates. They are including monoamines, amino acids, peptides, purines, and catecholamines. In the present study, the various types of neuropeptides and their applications in the nervous and peripheral systems were investigated. For this purpose, all data collection was performed in the general and specific databases. Finally, we proposed that critical neuropeptides such as neuropeptide y have a crucial role in certain and peripheral nervous systems
