Sequence the events that take place when a motor neuron's action potential triggers a muscle contraction.
Serhud [2]

Answer:

A,C,F,E,D,B

Explanation:

The is the sequence of  action potential transmission at  at the neuromuscular junction. Generally the arrival of action potential from the presynptic neuron caused influx of ca+ which causes migration and  the  release of the the acetycholine to the synaptic cleft.

The acetycholine binds with the receptors  on the saccolemma to causes opening of Na+ , its influx to causes depolarizarion  of the sacolemma. The depolarization of the latter spreads along the transverse tubules, This depolarization causes increases in the permeability of the sacorplasmic reticulum, with opening of ca+ channels and diffusion of Ca+ out of the  S. reticulum.

The Ca+ binds to troponin,and tropomyosin  exposed the myosin-binding sites on actin filament . The myosin head forms the cross bridges with the filament, and therefore the sacomere shortens leading causing muscle contraction.
