Most neurons follow the same general structural plan, but the structure of individual neurons varies and is adapted to the specific function a given neuron (or class of neurons) needs to …

Neurons (or nerve cells) are specialized cells that transmit and receive electrical signals in the body. Neurons are composed of three main parts: dendrites, a cell body, and an axon.

The organization of upper motor neurons (UMNs), lower motor neurons (LMNs), and sensory neurons creates a feedback system that modulates the strength of muscle contraction, …

There are about 85 billion neurons in your brain, and they’re sending electrical signals in your body right now! They tell your eyes to move across this page, interpret the words that you …

Chemicals called neurotransmitters transfer information between two neurons separated by a gap. These chemicals pass the information from axon terminal of the first neuron to the dendritic tip …

Uncover the roles and functions of neurons and glia, and how they work together to regulate our body's functions. Discover the structure of the nervous system, divided into the central and …

Learn about different types of neurotransmitter receptors and their roles in the nervous system on Khan Academy.

Action potentials being conducted down the axons of neurons are the way that neurons can transmit information over a wide range of distances, which may be one meter or more.

In this article, we'll take a closer look at the synapse and the mechanisms neurons use to send signals across it. To get the most out of this article, you may want to learn about neuron …
