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.
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.
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 …
The synapse (article) | Human biology | Khan Academy
How neurons communicate with each other at synapses. Chemical vs. electrical synapses.
Neurotransmitters and receptors (article) | Khan Academy
Here, we’ll focus on neurotransmitters, the chemical messengers released from neurons at synapses so that they can “talk” to neighboring cells. We’ll also look at the receptor proteins …
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.
Anatomy of a neuron (video) | 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.
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?
