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 …
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 …
Neuronal synapses (chemical) (video) | Khan Academy
There actually are certain neurons where there isn't any gap--electrical synapses connect directly because electrical signals cannot travel through a gap. Chemical synapses need the synaptic cleft so …
Motor neurons (video) | Muscular system | Khan Academy
How do neurons help us move? Learn about how motor neurons send signals to muscle cells and what happens when we damage this precious neurons. By Raja Narayan.
Neuron resting potential description (video) | Khan Academy
Explore the neuron resting membrane potential, a stable charge separation across the cell membrane. Discover the roles of anions and cations, and how their concentration differences create this …
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. Learn about the …
