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 *
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.
Where neuron cell bodies located?
The cell body, called the SOMA, is the main part of the neuron. It is the main metabolic center or region of the neuron. The neuron has 3 parts: DENDRITES (inputs), SOMA (cell body), and AXON (output). The axon is the part which FIRES when sufficient inputs reach it at the axon hillock.
What is the junction where the axon terminal of a sending neuron communicates?
The question isn't clear enough. Does it mean the part that sends info. through the neuron (the axon)? Or does it mean the part that sends information to other neurons (the synapse)?
What region of the cell secretes neurotransmitters?
Neurotransmitters are typically synthesized and stored in the synaptic vesicles of the presynaptic terminal, which is located at the end of the neuron. When an action potential arrives, these vesicles release neurotransmitters into the synaptic cleft to communicate with the postsynaptic neuron.
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.

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 long process of a neuron is called 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.
The anatomical region of a multipolar neuron that has the lowest threshold for generating an action potential is?
The axon hillock is the anatomical region of a multipolar neuron that has the lowest threshold for generating an action potential. This is because it contains a high density of voltage-gated sodium channels, making it more excitable compared to the soma or dendrites.
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 an axon-terminal?
An axon terminal is the structure of a neuron (a single cell of the central or peripheral nervous system) at the end of it's axon that forms a synapse with another neuron. Generally, the axon terminal is the point at which a neuron passes information to the neurons with which it is connected.
