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 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.
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.
Neurons (practice) | Neurons and Brain | Khan Academy
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 …
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.
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?
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 …
