Axon sends the message. Dendrite receives it.
Afferent
Presynaptic neuron sends postsynaptic receives
That would be an interneuron otherwise known as an associative neuron.
motor neurons are linked to the muscles and obviously sends a message for muscles to move
Sensory nerve fibers carry message to brain. A part of neuron or or single neuron does not carry this message to the brain.
The Motor in an abafatirc muscle so it sends an inpluse to the heart
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
A neuron sends a message, or neurotransmitter, to the muscle cell to tell it what to do. To get the message, the receiving cell must have a receptor. Oddly, the unstable protein rapsyn is responsible for anchoring the receptor so it's properly positioned to catch the message.
When a neuron in a muscle is fired, or triggered, it sends a message to the brain telling the muscle to contract.
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 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)?
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.
