Regardless of type, all neurons transfer signals between each other or to effectors (muscles or glands) at a synapse. The neuromuscular junction that we talked about with the muscular system is one example of a synapse. The diagram below shows the general features of a synapse Match each term or description with the appropriate letter in the diagram. You may use terms more than once. 1. Synaptic knob in axon terminal of pre-synaptic cell: 2. Synaptic cleft: 3. Neurotransmitter: 4. Dendrite of post-synaptic cell: 5. Cell body of post-synaptic cell: 6.
