  1. 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 carry out.

  2. 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. Learn about the …

  3. 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.

  4. 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 environment, move …

  5. 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.

  6. 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 structure and action …

  7. 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?

  8. 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. Electrons are found …

  9. 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.
