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 …
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.
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
This video introduces the function and functional types of neurons. Neuron function involves processing and transmitting information. Key components include resting potential, action …
The synapse (article) | Human biology | Khan Academy
How neurons communicate with each other at synapses. Chemical vs. electrical synapses.
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 …
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 …
Anatomie eines Neurons (Video) | Khan Akademy
Neuronen (oder Nervenzellen) sind spezialisierte Zellen, die elektrische Signale im Körper übertragen und empfangen. Neurone bestehen aus drei Hauptbestandteilen: Dendriten, einen …
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.
Introduction to neural cell types (video) | Khan Academy
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 …
