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.

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

​Read about Lactic Acid!  http://www.brianmac.co.uk/lactic.htm_  This is a longer read with biological processes included!

Excellent read about who is the real MVP in the lactic acid debate.  http://www.details.com/story/lactic-acid-workout
