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 contractsarrow_forward

Explain the function of each component in #1. 3. Mark the following statements as TRUE or FALSE: An action potential is something that only occurs at synapses. Afferent pathways send sensory information to the CNS for processing. When they are at rest, neurons are more positively charged inside than outside the cell. FALSE Action potentials originate at the axon terminal and move towards the dendrites. An action potential travels down the length of the neuron with the help of voltage-gated calcium channels. Neurons can only have one action potential and must be recycled by glia once they have depolarized. At axon terminals, calcium influx stimulates vesicle release. Ligand-gated ion channels open in response to a molecule binding to them. 4. For each FALSE statement in #3, explain why it is incorrect.
