Importance of neuromuscular junction
WitrynaWell, 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. Witryna7 maj 2024 · In a recent study undertaken at the Yale University School of Medicine, researchers determined that the muscles lining blood vessels in the brain actually contract after a stroke. This constricts the vessels, reduces blood flow to the brain, and appears to contribute to permanent brain damage.
