Once an action potential begins, there is a rapid depolarization of the neuron's membrane due to the influx of sodium ions (Na+) through voltage-gated sodium channels. This is followed by repolarization as potassium ions (K+) exit the cell, restoring the membrane potential. The action potential travels along the axon, propagating in a wave-like manner through the opening of adjacent ion channels, while the surrounding areas temporarily enter a refractory period, preventing immediate re-excitation. This process facilitates the transmission of electrical signals along the neuron and ultimately leads to neurotransmitter release at the synapse.
What else can I help you with?
When the action potential gets to the end of the axon?
When the action potential reaches the end of an axon, it causes special chemical messages called neurotransmitters to be released across the space between the neurons (the synapse).
Why is the pleural cavity called potential space?
The pleural cavity is called a potential space because under normal conditions, there is a small amount of lubricating fluid present that allows the layers of the pleura to slide smoothly over each other during breathing. This space does not normally contain air or excess fluid, but it has the potential to accumulate air or fluid in certain abnormal situations.
What is the space junction between two neurons called?
The space junction between two neurons is called a synapse. It is a small gap where the electrical signal in the form of an action potential is converted into a chemical signal in the form of neurotransmitters to allow communication between neurons.
Is potential gradient vector or scalar?
The potential gradient is a vector quantity. It represents the rate of change of the scalar electric potential with respect to position in space.
The potential space between the pleural membrane is called the?
The potential space between the pleural membranes is called the thoracic cavity. This is also known as the pleural cavity in some instances.
Is there a word from Space that begins with z?
Zero gravity is a space word. It begins with the letter z.
What is a space word that begins with letter H?
Hubble telescope is a space word. It begins with the letter h.
What happens when an impulse reaches the synapse?
When the action potential reaches the end of an axon, it causes special chemical messages called neurotransmitters to be released across the space between the neurons (the synapse).
What begins with g and has to do with space?
Gravity
A word that begins with b for outer space?
Big dipper is an outer space word. Black hole is another outer space word that begins with the letter b.
Is there anything in space that begins with the letter A?
Asteroids are in space. The U.S. Apollo spacecraft flew in space.
What space word begins with Y?
Year
How do you make more free space for your action replay?
What do you do when action replay has no free space when you have no codes?
When the action potential gets to the end of the axon?
When the action potential reaches the end of an axon, it causes special chemical messages called neurotransmitters to be released across the space between the neurons (the synapse).
Space words that starts with a W?
Weightlessness is a space word. It begins with the letter w.
Are there any space words beginning with t?
A space word that begins with T is trajectory.
Is there anything in space that starts with h?
The Hubble telescope is in space. It begins with the letter h.
