What Happens Before, During, and After an Action Potential?: The action potential plays a vital role in transmitting neural impulses.

The nervous system functions as a communication system, transmitting messages in the form of action potentials along the axons of neurons and in the form of neurotransmitters at synapses between neurons and the cells they control.

Action Potential A neuron can receive input from other neurons and, if this input is strong enough, send the signal to downstream neurons. Transmission of a signal between neurons is generally carried by a chemical called a neurotransmitter. Transmission of a signal within a neuron (from dendrite to axon terminal) is carried by a brief reversal of the resting membrane potential called an action potential. When neurotransmitter molecules bind to receptors located on a neuron’s dendrites, ion…

This graphic proves that all living things detect and respond to stimuli by explaining how the reflexes in our knee work.

This is my favorite part. Especially when its involving the muscular system. So amazing.

Great picture of what the synapse is. This is such a cool thing because of the synaptic cleft. To know that they aren't physically touching, but specific neurotransmitters diffuse across to continue the impulse is so cool.

Action potential

So we covered the basics of radio waves. Let’s assume you’ve cooked it properly so you’re not dealing with bacteria/worms that raw meat in general.

Neurons firing na channels activate de polarizing after passing the threshold k blocks na channels by ball and chain block and k floods out over shooting before resetting

This diagram shows how sodium and potassium ions are pumped through protein channels. The sodium ions are pumped out of the cell, while potassium is pumped into the cell. The movement of these ions creates resting potential and action potential.
