This is a concise, fast-paced lesson that has been designed to enable students to discover the key structural features of a synapse and be able to write accurate descriptions of the sequence of events that occur at these structures. The neurotransmitter involved is acetyl choline and therefore this is specifically a lesson about cholinergic synapses. The lesson begins by going through the terminology associated with synapses which includes pre-synaptic terminal or knob, synaptic cleft and post-synaptic neurone. Then time is taken to look at each of the two neurones and the structures found inside the terminal or on the membranes. The main task of the lesson involves a step by step guide through the sequence of events at the synapse. This guide has been written in a bullet point format and students are challenged to use the features they have met and their own Biological knowledge to complete each point. The final part of the lesson looks at how the enzyme acetylcholinesterase is involved in the breakdown and then how the neurotransmitter is re-formed using the ATP generated in the mitochondria This lesson is written for A-level students
