Introduction to neurons and glia. How the structure of a neuron allows it to receive and transmit information.

So if I were to draw a neuron-- let me pick a better color. So let's say I have a neuron. It looks something like this. So in the middle you have your soma and then from the soma-- let me …

My neuroscience textbook classifies any neuron with two neurites as bipolar, and the diagram shows what you describe: the bipolar neuron has two axons going in opposite directions.

Most of your synapses are chemical synapses, meaning that information is carried by chemical messengers from one neuron to the next. In the article on synapses, we discussed how …

As you may remember from the article on neuron structure and function, synapses are usually formed between nerve terminals—axon terminals—on the sending neuron and the cell body or …

Action potentials (those electrical impulses that send signals around your body) are nothing more than a temporary shift (from negative to positive) in the neuron’s membrane potential caused …

The membrane potential of a resting neuron is primarily determined by the movement of K + ions across the membrane. So, let's get a feeling for how the membrane potential works by seeing …

Hyperpolarization is when the membrane potential becomes more negative at a particular spot on the neuron’s membrane, while depolarization is when the membrane potential becomes less …

So let me start by showing where synapses happen, so first I'll draw the soma of a neuron in red, and a few dendrites, these branching processes of neurons in blue, one dendrite and here's …
