The synapse (article) | Human biology | Khan Academy
A single axon can have multiple branches, allowing it to make synapses on various postsynaptic cells. Similarly, a single neuron can receive thousands of synaptic inputs from many different …
Synapse structure (video) | Khan Academy
This video discusses synapses, where neurons communicate with target cells. It differentiates between two types of synapses: chemical and electrical. It also explains the role of the …
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 …
Neurotransmitters and receptors (article) | Khan Academy
In the article on synapses, we discussed how synaptic transmission works. Here, we’ll focus on neurotransmitters, the chemical messengers released from neurons at synapses so that they …
Neuronal synapses questions (practice) | Khan Academy
Neuronal synapses questionsWelcome to Khan Academy! So we can give you the right tools, let us know if you're a...
Signal propagation: The movement of signals between neurons
Synapses between neurons are either excitatory or inhibitory – and that all comes down to the neurotransmitter released. Excitatory neurotransmitters cause the signal to propagate - more …
Overview of neuron structure and function - Khan Academy
These connections, known as synapses, are the sites at which information is carried from the first neuron, the presynaptic neuron, to the target neuron (the postsynaptic neuron).
The synapse (article) | Human biology | Khan Academy
A single axon can have multiple branches, allowing it to make synapses on various postsynaptic cells. Similarly, a single neuron can receive thousands of synaptic inputs from many different …
Neurotransmitter release (video) | Khan Academy
ARE SYNAPSES WITH NUEROTRANSMITTERS ALWAYS OPENED WITH VOLTAGE GATED CALCIUM CHANNELS? there are multiple types of ion channels how do I keep track of them. …
Neuroplasticity (video) | Khan Academy
This process involves changes in synapses and neurons, leading to potentiation or depression of information flow. It's most active during development, but continues throughout life, with …
