Lesson Plan: Synapses Biology
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the structure of a synapse and explain how information is transmitted across synapses.
Students will be able to
- recall that neurons can form synapses with other neurons, muscle fibers, or gland cells,
- describe the structure of a cholinergic synapse, including the vesicles and the calcium ion channels of the presynaptic neuron and the acetylcholine receptors and sodium ion channels of the postsynaptic neuron,
- explain the mechanism of transmitting a nervous impulse across a synapse via the neurotransmitter acetylcholine,
- describe the role of acetylcholinesterase in breaking down acetylcholine,
- recall that transmission across a synapse is unidirectional.
Students should already be familiar with
- the fact that the nervous system transmits electrical impulses,
- action potentials.
Students will not cover
- details of synapses at neuromuscular junctions.
