How do neurons communicate? Describe how a neural impulse travels from a sending neuron to a receiving neuron. In your description, be sure to include the parts of a neuron and what happens at the synapse
What will be an ideal response?
Essay should include:
Neural impulse: Dendrites – receive messages from other neurons > Cell body -- contains nucleus of the cell > Axon -- (myelin sheath insulates, speeding transmission) sends message from cell body > Terminal button of axon > Synapse > Receiving neuron. Synapse: gap between sending neuron and receiving neuron. As impulse reaches axon terminal of sending neuron, neurotransmitters (chemical messengers) are released and travel across synapse; they fit into specific receptor sites on receiving neuron – completing the transmission.
