describe a skeletal muscle fiber contraction starting
by exciting a motor neuron with an EPSP. talk about local
potentials leading to an action potential. Describe an action
potential and what it causes at the axon terminal. Talk
about   neuromuscular junction, the motor end plate(whats
found here and nowhere else in the muscle fiber?) the excitement of
the muscle fiber, what happens inside the cell when it is excited.
Mention the regulatory proteins and the contractile proteins and
their involvement in the contraction. Lastly, describe how the
muscle relaxes.
