Review the videos below on the steps of muscle contraction:

1) Events at the neuromuscular junction

2) Excitation-contraction coupling

3) Crossbridge cycle

These videos illustrate the steps that occur for skeletal muscle cells, which are very similar to cardiac, heart, muscle cells which contract in a very similar way.

1 Now outline how alterations at the chemical level cause complications at the organismal level: How does crude oil interrupt heart cell signaling and overall heart cell function? What does this do to the fish?

2 An outline of the research techniques used in this study, including brief description of each technique.
