While this unit is about how neurons send messages - you will also learn a lot about molecular movement across the biological membranes. Specifically, you will be immersing yourselves into the Neuromuscular Junction (NMJ). The NMJ is the connection between a specific type of neuron, the motor neuron, and a muscle cell. It is this interaction that enables us to move our muscles. However, what happens within this specific example is similar to what happens in all of your neurons. Before we get too far into the NMJ, let's begin with a tour of the Nervous System in general and your brain.
