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.
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 is the function of the axon hillock?
The axon hillock is a specialized region of a neuron where action potentials are initiated. It integrates signals from the cell body and dendrites, and if the incoming signals are strong enough to reach the threshold, it generates an action potential that propagates down the axon.
Where does the action potential occur on a neuron?
The action potential occurs at the axon hillock, which is the initial segment of the axon where the cell body transitions into the axon. This is where the threshold potential is reached and an all-or-nothing electrical signal is generated and propagated down the axon.
Where in a neuron can an action potential be generated?
An action potential is generated at the axon hillock of a neuron, which is the region where the cell body (soma) transitions into the axon. This is where the concentration of voltage-gated sodium channels is highest, allowing for the initiation of the action potential.
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.
The axon is connected to the soma by the?
axon hillock
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.
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 part of a neuron attaches the cell body to the axon?
The part of a neuron that attaches the cell body to the axon is called the axon hillock. It is located at the base of the cell body and is responsible for integrating incoming signals to generate an action potential.
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 soma forms a cone shaped as it projects to form an axon?
Axon Hillock
What is the name of the area where nerve impulses arises?
receptive region?
The first voltage-regulated gates encountered along the neuron membrane which initiate the formation of action potentials are located on the neuron near the?
axon hillock
Where is the hillock of the neuron?
The nerve cell hillock is the beginning of the axon immediately after the soma. This is where the action potential originates.
Where does the action potential occur on a neuron?
The action potential occurs at the axon hillock, which is the initial segment of the axon where the cell body transitions into the axon. This is where the threshold potential is reached and an all-or-nothing electrical signal is generated and propagated down the axon.
