A single neuron can’t do very much by itself, and nervous system function depends on groups of neurons that work together. Individual neurons connect to other neurons to stimulate or inhibit their …

Neuron function involves processing and transmitting information. Key components include resting potential, action potentials, and the roles of dendrites, axons, and neurotransmitters.

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 by ions …

Explore the structure of neurons, their types, and functions. Uncover the roles of dendrites, axons, and the soma. Learn about the axon hillock, axon terminals, and the myelin sheath. Discover the different …

And then we're going to talk a little bit about how it performs its function, which is essentially communication, essentially transmitting signals across its length, depending on the signals it receives.

Sometimes different parts of different cells perform other functions, but these tend to be where the neuron receives its signal. And we'll talk more about what it means to receive and transmit a signal in …

This is why the brain uses neuron networks to send many signals to a single cell, or why a neuron may have to fire a couple times before it can pass the message along.

Key points: A resting (non-signaling) neuron has a voltage across its membrane called the resting membrane potential, or simply the resting potential. The resting potential is determined by …

But most of its membrane is actually wrapped around the axon as the myelin sheath. In addition to these functions, Schwann cells also appear to influence neurons, and vice versa, through exchange of a …
