How is the structure of a neuron related to its functions?
The function of a neuron is to convey or process signals.The structure of a neuron allows these functions to occur.The relevant components of a neuron comprising its structure are:dendrites (inputs), soma(cell body), axon hillock (signal strength assessing trigger point), axon (output), axon terminal branches, and axon terminal buttons.Neurons receive signals, either from other neurons, or from receptor cells; they either simply convey the signal along the axon, or evaluate its strength and send it along the axon if the input is strong enough.The structure of the neuron allows this function to happen in the following way: the dendrites receive chemical messengers through a synapse from an axon terminal button, which opens pores in the dendrite which allow sodium ions in, creating an electric voltage; this voltage propagates down the dendrite and over the somato the axon hillock, where, if it is greater than a triggering value, it can cause the axon to fire an action potential along its length; when the action potential reaches an axon terminal button, it causes calcium ion pores to open in the button, which causes small bags of neurotransmitter chemicals to merge with the membrane of the terminal button, releasing the neurotransmitter chemicals into the synaptic cleft (gap), where they diffuse over to a dendrite.

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.
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 is terminal branch of axon?
dendrite
A nerve impulse starts at the dendrite then travels to the?
cell body, continues down the axon, and finally reaches the axon terminal. At the axon terminal, the impulse triggers the release of neurotransmitters to communicate with other neurons or muscles.
What part of neuron releases neurotransmitter my choices are axon axon terminal dendrite myelin sheath or cell body?
The neurotransmitter is released from the axon terminal.
Impulse generator and transmitter?
axon terminal
What does the letter Represent on this diagram?
axon terminal
When an action potential reaches an axon terminal, what happens to the neurotransmitters?
When an action potential reaches an axon terminal, it triggers the release of neurotransmitters into the synaptic cleft.
