Overview of neuron structure and function - Khan Academy
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 …
Overview of neuron structure (types of neurons) - Khan Academy
This video introduces the structure and structural types of neurons. Explore the structure of neurons, their types, and functions. Uncover the roles of dendrites, axons, and the soma. …
Anatomy of a neuron (video) | Human biology | Khan Academy
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 synapse (article) | Human biology | Khan Academy
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 …
Depolarization, hyperpolarization & neuron action potentials …
In neurons, the cell enters a state of hyperpolarization immediately following the generation of an action potential. While hyperpolarized, the neuron is in a refractory period that lasts roughly 2 …
Signal propagation: The movement of signals between neurons
Your brain is a hotbed of electrochemical activity. About 100 billion neurons are each firing off 5-50 messages (action potentials) per second. This activity allows you to process your …
Membrane potential (resting membrane potential) (article) - Khan …
In neurons, the resting membrane potential depends mainly on movement of K + through potassium leak channels. Let's see how this works.
Neuron action potentials: The creation of a brain signal
Neurons are similar to other cells in that they have a cell body with a nucleus and organelles. However, they have a few extra features which allow them to be fantastic at transferring action …
PhET simulation: Exploring action potentials - Khan Academy
Follow the link to dive deeper into the world of neurons using an interactive PhET simulation!
Neuron action potential description (video) | 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.
