The dendrites are the "input" portion of the neuron, collecting signals from other neurons. However, the axon is the "output" portion of the neuron, sending signals to other neurons.
Your nervous system sends messages from the body to the brain. Different kinds of Neurons are used to send each message, to allow your brain to know what is going on in your environment. The things that cause a reaction are called Stimuli. Messages are sent along nerve cells, or Neurons. For instance, if you prick your finger on a pin, a sensor in your skin called a Receptor sends a message of pain through a Sensory Neuron, to a Relay neuron in your Central Nervous System (which is your brain and spinal cord). The message is then sent through the CNS, to the brain, so your brain can decide how to react to the pain. The message is THEN sent through a motor neuron, which causes your muscles to move to react to the message. (Something that reacts to a message from a neuron is called an Effector- because it causes an effect.) In this case, the message from the motor neuron to the effector- your muscle- would make you pull your hand back, to get it away from the pin. In short: A change in your environment, like pain, is picked up by a Receptor. The message picked up by the Receptor is sent through a Sensory Neuron. The message is then sent through the Central Nervous System by Relay Neuron. Once the brain has decided what to do, it sends a message to the Motor Neuron. The Motor Neuron triggers an Effector (a muscle, or some chemical secretion) to react to the change. It may not be completely correct, but I'm 90% sure that's at least a rough, simple version.
The axon of a neuron is the part that sends information to other neurons or cells in the body. It transmits electrical signals known as action potentials from the cell body to the axon terminals where communication with other neurons occurs.
The end of one neuron, the presynaptic button, sends messages to other cells by releasing neurotransmitters (chemical messengers) into the synaptic cleft (a small space between two neurons). The other cell, whether it be a neuron, a muscle, a sweat gland, etc., will receive this message at the post synaptic membrane of its cell, and will respond accordingly.
Yes. A synapse by definition is the space (gap) between one neurons terminal buton and another neurons dendrites. So, the neuron with the terminal buton end is known as the pre-synaptic neuron and the neuron after the synapse is known as the post-synaptic neuron.
The sensory neurons in your peripheral nervous system are responsible for detecting pain signals from your body and transmitting them to your brain. These neurons are equipped with specialized receptors that respond to stimuli like temperature, pressure, and tissue damage, sending electrical signals along nerve pathways to your brain to signal pain.
Axon sends the message. Dendrite receives it.
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)?

This is what happens:a receptor detects a stimulus (change in the environment)a sensory neuron sends a signal to the relay neuronthe relay neuron sends the signal to the motor neuronthe motor neuron sends a signal to the affected partthe affected part produces a response
Signalling ALONG a neuron is electrical, but signalling BETWEEN neurons is a chemical process. Neuron A 'passes' a message onto the next by releasing chemicals called neurotransmitters , which are then taken up by neuron B. The point at which these neurotransmitters are released from the neuron A is called the 'terminal bouton' and is the end of its axon. More specifically, it is the presynaptic membrane OF the terminal bouton at which the passing on of a message occurs.
The axon terminal is the part of the nerve responsible for sending the message at all. Not only does it send the message, though, it has branching paths which allow it to determine which path it'll go on.
Messages from the neuron always travel from the cell body down the axon.
