axon
The body.
The dendrites are the receiving part of the neuron.
dendrite
The axon terminals of a neuron are responsible for relaying signals from one neuron to another neuron or to an effector, such as a muscle or gland. When an action potential travels down the axon, it triggers the release of neurotransmitters at the axon terminals, which then stimulate the next neuron or target cell.
No they cannot. Once a Sand Dollar is broken it cannot grow back any part of its body. --- Shawn Caudill
The axon, an elongated portion of the neuron, carries impulses to the muscles.
Motor Neuron
The axon is the part of the neuron that can carry information for long distances.

Sensory neuron and motor neuron.
Cell Body
The synaptic cleft is the area of the neuron that secretes neurotransmitters.
It depends on what you mean by 'main'. The AXON is the part which CONVEYS the neural impulse, which could be thought of as the main FUNCTION of the neuron. But the DENDRITES are the parts which assess whether the neuron has been stimulated enough to fire the axon, which is another fundamental function of some neurons. And the BODY (soma) of the neuron is very much a 'main' part of the neuron, because without it the neuron would die.
