WebWell, in this video, we'll talk about the place where neurons talk directly to muscles. That's the neuromuscular junction, the junction of where motor neurons talk to muscle cells. So that involves, first, the axon terminal. This is the end of an axon, which is the part of a neuron that casts a signal away. And it looks like this. WebSkeletal Muscle Cell. In cultured skeletal muscle cells and C2C12 myotubes, Ucn 2 inhibits insulin-induced Akt and ERK1/2 phosphorylation, consistent with the hypothesis that Ucn 2 functions as a local negative regulator of glucose uptake in skeletal muscle and suggests the possibility that suppression of the Ucn 2/CRH-R2 pathway may provide …
