The sequence of events along an axon involves the generation of an action potential at the axon hillock, propagation of the action potential down the axon via depolarization and repolarization of the membrane, and neurotransmitter release at the axon terminals to communicate with other neurons or target cells.
What else can I help you with?
What is the sequence indicating the normal flow in a nerve cell?
The normal flow of information in a nerve cell (neuron) follows this sequence: the signal begins at the dendrites, where it is received from other neurons. This electrical impulse then travels along the axon, reaching the axon terminals. From there, neurotransmitters are released into the synapse, transmitting the signal to the next neuron. This process allows for rapid communication within the nervous system.
What enters the axon during action potential?
Sodium ions enter the axon during action potential. This influx of sodium ions depolarizes the axon membrane, leading to the propagation of the action potential along the axon.
What support the axon from within?
The axon is supported from within by microtubules, which are part of the cytoskeleton. Microtubules provide structural support and help in the transport of molecules and organelles along the length of the axon.
Where is the point on axon that a signal can be transmitted?
Signals are transmitted along the axon at the axon terminals or synaptic boutons. These structures are located at the ends of axon branches and contain neurotransmitter-filled vesicles that are released into the synapse to communicate with neighboring cells.
Which part of the neuron can propagate an action potential?
The axon is the part of the neuron that can propagate an action potential. This process relies on the opening and closing of ion channels along the axon membrane to allow the action potential to travel from the cell body to the axon terminals.
Electrical change in the neuronal membrane that is transmitted along axon is?
Action potential is the term for an electrical change in the neuronal membrane transmitted along an axon. The axon is part of a nerve cell that conducts impulses.
What do you call events that occur in a sequence?
You call them 'sequence of events'.
A long structure leaving the cell body that action potential travel along is called the?
It is the Axon
What signal travels along the axon?
The high-speed signals that pass along the axon are called action potentials. They spread in a wave of depolarization.
What does not belong axon terminal synaptic knob bouton axon collateral?
Bouton does not belong as it refers to a swollen region along an axon where synapses are found, while axon terminal, synaptic knob, and axon collateral are all parts of the structure of a neuron.
Which is the correct sequence in the transmission of a neural impulse?
dendrite, cell body, axon, synapse
Where are action potentials regenerated as they propagate along a myelinated axon?
First at the axon hillock where the neural impulse is initially triggered, and then at the nodes of Ranvier as the impulse continues to travel along the axon.(Note that the impulse travels as electrotonic conduction between the nodes of Ranvier, underneath the glial cells which myelinate the axon.)

What is the sequence of events associated with the proper functioning of the pacemaker?
What is the sequence of events associated with the proper functioning of the pacemaker?
A record of events told in sequence is called?
historyA record of events told in sequence is called a Chronicle.
