Question

Draw a diagram!

The purpose of the diagram is to show the steps from a neuron stimulating a skeletal muscle cell to contraction of that muscle cell.

Include in your diagram:

•axon terminal of motor neuron

•synaptic cleft

•neurotransmitter

•neurotransmitter binding channels on muscle cell

•t-tubules

•depolarization

•sarcoplasmic reticulum

•receptors/channels that work together to release Ca2+

•Ca2+, Where is it? Where does it go? What does it bind to?

•Sarcomeres-components (actin, myosin, tropomyosin, troponin, ATP) and how it works (sliding filament theory)

Draw the diagram and label the parts. Include text to describe the steps.
