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.
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.
Depolarization, hyperpolarization & neuron action potentials …
Many different types, broadly categorized with respect to their shape or their function. Motor neurons, interneurons (AKA relay neurons) and sensory neurons are the traditional …
Neuron action potentials: The creation of a brain signal
Neurons are similar to other cells in that they have a cell body with a nucleus and organelles. However, they have a few extra features which allow them to be fantastic at transferring action …
Upper motor neurons (video) | Khan Academy
Located in the cerebral cortex, these neurons follow specific pathways and their dysfunction can impact reflexes and muscle tone. Understanding their role is key to unraveling the complexities …
