Human body from organs to the cells of which they are composed. The human body consists of many interacting systems of organs. These interact to maintain homeostasis, keeping the body in a stable state with safe levels of substances such as sugar and oxygen in the blood. Each system contributes to homeostasis, of itself, other systems, and the entire body. Some combined systems are referred to by joint names. For example, the nervous system and the endocrine system operate together as the neuroendocrine system. The nervous system receives information from the body, and transmits this to the brain via nerve impulses and
Perisynaptic schwann cells research conducted in the past two decades. The origin of Perisynaptic (Terminal) Schwann Cells was largely under question in the 1960s as there were arguments on whether the cells were of epithelial or glial descent, but the development of PSCs has been linked to Neural crest origin. As described above, PSCs are a type of non-myelinating Schwann cell, which develop from neural crest cells. The general series of developmental events can be summarized as this: Neural Crest cells develop into Schwann cell precursors which further develop into Immature Schwann cells which then differentiate into Myelinating Schwann cells and non-Myelinating schwann
