An axon hillock is part of a neuron that acts as a bridge between the cell body and the axon. Electrical impulses from the dendrites and cell body are summed at this point, which is then sent down the axon.

Where do action potentials occur?
The spike initiation zone, also called axon hillock, is the point where the cell body of the neuron meets the axon and is the point where most action potentials are initiated.
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 *
Where in a neuron can an action potential be generated?
axon hillock
What structure is the axon hillock the orgin of?
Is defined as the distance and direction from the orgin to an
The trigger zone of a neuron includes?
The axon hillock and the initial segment
What part of a neuron attaches the cell body to the axon?
axon hillock
Which region of the cell body from which the axon originates?
The axon (in motor neurons) begins just distal to a slightly enlarged cell body structure called the axon hillock.
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?
The spike initiation zone, also called axon hillock, is the point where the cell body of the neuron meets the axon and is the point where most action potentials are initiated.
The anatomical region of a multipolar neuron that has the lowest threshold for generating an action potential is?
Axon hillock
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?
Where in a neuron can an action potential be generated?
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.
Why does a normal axon always propagate action potentials from the axon hillock to the axon terminals?
It is very difficult to answer this question. But this is the basic mechanism in case of diodes of the electronics also. It can be easily explained there. With out such unidirectional flow nervous system can not function at all.
