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.
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 peripheral …
Nervous system physiology and disease - Khan Academy
There are about 85 billion neurons in your brain, and they’re sending electrical signals in your body right now! They tell your eyes to move across this page, interpret the words that you read, maintain your …
Multiple sclerosis pathophysiology (video) | Khan Academy
So what makes up the gray and white matter, well, if you'll remember, the brain is made up of about 86 billion neurons. Those 86 billion neurons are gonna compose the gray matter and the white matter. …
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.
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 of our …
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 Zellkörper und ein …
Neuron resting potential mechanism (video) | Khan Academy
So while the concentration gradients of chloride and calcium ions tend to have little effect on the resting membrane potential of most neurons, they do play major roles in other aspects of neuron functions.
Structure of the nervous system (video) | Khan Academy
Information travels in two directions: from the periphery to the central nervous system via afferent neurons, and from the central nervous system to the periphery via efferent neurons. This system …
