Neurons send internal messages through the use of action potentials, which are generated through the summation of inputs from the dendrites on the other part of the neuron. These inputs are summed either temporally (over a period of time) or at the same time (instantaneous), and if they push the voltage in the zone of the axon hillock to above threshold, it results in the generation of an action potential.
The action potential travels through the axon, and once it reaches the terminal bouton of the axon, it triggers calcium influx into the cell, which causes neurotransmitter release. Neurotransmitter release may either be excitatory or inhibitory depending on the neurotransmitter released; for example, in the CNS, glutamate is the major excitatory neurotransmitter, whereas GABA is the major inhibitory neurotransmitter. They bind to the post-synaptic cell, which triggers the post-synaptic cell response.
Note that this is just a general overview for neural transmission; some neurons may have different mechanisms of action.

What receives neuron messages and sends them to the cell body?
The dendrite receives a stimulus and conducts the nerve impulse toward the cell body.
Which system sends and receives messages within the body?
There isn't any. You're thinking of the nervous system - but the messages are all chemical. The electrical activity is a side effect.
What messages does GABA send to a receiving neuron?
GABA sends______messages to a recieving neuron
What structure in the neuron sends signals to the organs?
yes
What is the function of the giant multipolar neuron?
Giant multipolar neurons are neurons that have three of more processes attached to their cell bodies. A majority of multipolar neurons are involved in movement.
What is the importance of a neuron?
A neuron sends messages from your brain to your body
What type of cell sends and receives messages?
Neuron
How is a neuron different from an ordinary body cell?
A neuron is different from an ordinary body cell because it transmits messages throughout the brain. It also sends electrical messages.
How does a neuron sends messages to a cell?
I think the brain makes a shock and goes down to your spinal cord and goes to the cell
What part of the neuron sends information to others?
Presynaptic neuron sends postsynaptic receives
What receives neuron messages and sends them to the cell body?
The dendrite receives a stimulus and conducts the nerve impulse toward the cell body.
Which part of a neuron is attached to the soma and carries messages out to other cells?
Apex question is which is a part of a neuron that sends out messages answer axon
What is intermixed neuron?
a neuron which recieve both messages from afferent and efferent neuron...
What type of nerve sends messages to muscles?
The nerve synapses transmit messages form one nerve to another.
Which system sends and receives messages within the body?
There isn't any. You're thinking of the nervous system - but the messages are all chemical. The electrical activity is a side effect.
What is an extension of the neuron cell body that sends information away from the neuron?
the axon
What is an axon and what is its job?
An axon is the extension of a neuron and it sends nerve impulses away from the cell. In simpler words it is the "tail" of a nerve cell which sends messages to other cells.
