Verified step by step guidance

Understand the structure of a neuron: Neurons consist of a cell body, dendrites, and an axon. The axon terminal is where neurotransmitters are released.

Learn about synapses: A synapse is the junction between two neurons, consisting of a presynaptic ending that contains neurotransmitters, a synaptic cleft, and a postsynaptic ending that contains receptor sites.

Explore the role of neurotransmitters: Neurotransmitters are chemical messengers that transmit signals across the synaptic cleft from one neuron to another.

Examine the process of neurotransmitter release: When an electrical impulse reaches the axon terminal, it triggers the release of neurotransmitters into the synaptic cleft.

Understand receptor binding: Neurotransmitters bind to specific receptors on the postsynaptic neuron, initiating a response that can lead to the continuation of the electrical signal.
