Topic 4.  Movement Analysis

This topic explores planes, joints and joint actions.   We look at HOW and WHY muscles contract and the interaction of movement in the environment.  

4.1 - Neuromuscular Function
4.1.1      Label a diagram of a motor unit
4.1.2      Explain the role of neurotransmitters in stimulating skeletal muscle contraction.
4.1.3      Explain how skeletal muscle contracts by the sliding filament theory.
4.1.4      Explain how slow and fast twitch fiber types differ in structure and function.

Why do we learn about neurotransmitters and muscle contraction?
 - Alzhiemer's and Acetylcholine - "Doctors are now willfully poisoning acetylcholinesterase in an attempt to reverse the symptoms of Alzheimer's disease. People with Alzheimer's disease lose many nerve cells as the disease progresses. By taking a drug that partially blocks acetylcholinesterase, the levels of the neurotransmitter can be raised, strengthening the nerve signals that remain." - http://pdb101.rcsb.org/motm/54
