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. …
Overview of neuron function (video) | Khan Academy
Neurons receive excitatory or inhibitory input from other cells or from physical stimuli like odorant molecules in the nose. Input information usually comes in through the dendrites.
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 …
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 …
Electrotonic and action potentials (video) | Khan Academy
Wait. So how do the dendrites even respond to a signal. and what would be the defintion of a signal if you are dealing with neurons?
Protons, neutrons, and electrons in atoms - Khan Academy
Atoms are made up of three types of subatomic particles: protons, neutrons, and electrons. Protons and neutrons are found in the nucleus, the dense region at the center of an atom. …
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.
