The axon is a long, slender projection of a neuron that transmits electrical impulses away from the neuron's cell body to communicate with other neurons, muscles, or glands. It is typically covered by a myelin sheath, which enhances the speed and efficiency of signal conduction. Axons end in terminal buttons that release neurotransmitters, facilitating synaptic transmission. Overall, the axon plays a crucial role in the nervous system by enabling rapid communication between different parts of the body.
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 *
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.
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.
Is and axon bulb and an axon hillock the same thing?

The axon is connected to the soma by the?
axon hillock
The axon is made up of?
what is the axon made of
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
The long process of a neuron is called the?
Axon
Which region of the cell body from which the axon originates?
The axon originates from the axon hillock, a specialized region of the cell body that connects to the initial segment of the axon. This area is important for integrating incoming signals and deciding whether to generate an action potential.
What is the very beginning of the axon called?
The very beginning of the axon is called the axon hillock. It is where the electrical signals from the cell body are gathered and then transmitted down the axon.
When did William Axon die?
William Axon died in 1913.
When was William Axon born?
William Axon was born in 1846.
