As far as I understand it, the purpose of the axon is to transmit the electrical impulses (information) of the presynaptic dendrites away from the cell body. The axon therefore acts as a sort of barrier between the postsynaptic dendrites, as it is kind of a one-way street from the cell body to the postsynaptic dendrites. As for why this is necessary, I have no clue. I would assume that if electrical information were to get caught up and stuck somewhere in the cell that it might be damaging to the neuron itself. The purpose of the axon would ultimately be to get the electrical information from the cell body to the postsynaptic dendrites so that chemical production on the neurotransmitter takes place.
What else can I help you with?
Is and axon bulb and an axon hillock the same thing?
axon hillock = where cell body meets the axon axon bulb = end of the axon...lies very close to the dendrites of another neuron so impulses can pass over the synapse. AP Biology student *
What purpose does the myelin covering an axon serve?
Myelin acts as an insulating layer around the axon, allowing for faster transmission of electrical impulses. It helps to speed up nerve conduction and prevents signal loss by reducing interference between neighboring nerve fibers.
The axon of each motor neuron has numerous endings are called what?
The tip of a neuron's axon culminates in several endings call terminal buttons. When an action potential is conducted down the axon, this is where it goes.
What is the side branch of the axon?
The side branches of the axon are called axon collaterals. They are smaller branches that extend from the main axon and allow for communication with multiple target cells simultaneously. Axon collaterals play a key role in neural communication and signal transmission.
Where do action potentials occur?
Action potentials occur along the axon of a neuron, where the electrical signals are transmitted from the cell body to the axon terminals. The action potential is initiated at the axon hillock and propagates down the axon to trigger the release of neurotransmitters at the synapse.
Axon diameter increases noticeably at the nodes of ranvier What purpose does this serve?
the axonal diameter increases due to the myelin wraped tightly around the axon.
How far would an action potential propagated in an unmyelinated axon?
The impulse will go to the terminal end of the axon. Other wise the very purpose of the innervation will be defeated.
What is the purpose of wallerian degeneration?
Degeneration of the axon and myelin sheath distal to the injury site caused by the lack of nutrients.

What is the purpose of myelin sheath?
This is a process that occurs in the CNS and PNS with axons. In the CNS oligodendrocytes surround the axons and in PNS schwann cells surround the axons. the myelin sheath will increase the speed of nervous conduction along the axon.
The axon is connected to the soma by the?
axon hillock
The axon is made up of?
what is the axon made of
What purpose does the myelin covering an axon serve?

What is a axon hillock?
An axon hillock is a special cell body that connects an axon to a neuron. It is the last place where propagated membrane potentials are transmitted to the axon.
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.
What synapses release acetylcholine?
sympathetic preganglionic axon parasympathetic preganglionic axon parasympathetic postganglionic axon
Why was the squid axon particularly appropriate for nerve research?
The squid axon is the largest axon known in the whole animal kingdom, the axon of the squid is also very much like humans and most mammal axon, thus making is an ideal axon to use during research
