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 These proteins are seen in other glial cells such as Myelinating Schwann cells and Neural Crest cells. While the lineage of non-Myelinating Schwann cells is known from neural crest cells, the exact development of PSCs from non-Myelinating Schwann cells is not fully understood. Synaptogenesis is the formation of a synapse and in this case the Neuromuscular Junction is of interest. In this section, the focus is on the development of the NMJ from the outgrowth of axons during development. As mentioned in the development section, Schwann cell precursors accompany growing axons as they reach their associated muscles. It is now
