Much of our current understanding of synapse development originated from studying the neuromuscular junction. What are the special features of the neuromuscular junction that make it a useful model system for synaptogenesis? As an example, describe a study that could not have been made in synapses in the central nervous system.
Order the steps of the neuromuscular junction transmission using the following images. Then, usethe to describe what is happening in the step.
Neuromuscular Junction Transmission - Contraction
1. Action potential travels from motor neuron cell body along the myelinated axon to neuromuscular junction.
2. Acetylcholine (ACh) is released from axon (neuron), crosses synapse (space between axon and sarcolemma).ACh binds to ACh receptors (channel) in sarcolemma.
3.ACh channels open. Ions (like sodium, Na+) flow into sarcolemma.Action potential spreads in sarcolemma and into transverse tubules.
4. Action potential causes the release of calcium (Ca2+) from sarcoplasmic reticulum into sarcoplasm
5.Ca2+ goes to the troponin, which moves the tropomyosin away from actin
6. Myosin head breaks down ATP, causing the sliding filament mechanism to shorten sarcomereMuscle contracts
