Dogs Being Trained to Sniff Out the Early Signs of Parkinson's Disease

Parkinson's mainly involves the skeletal muscles, as these muscles can be felt and seen. Think a bicep, and what you see if someone flexes that bicep. When we exercise to build muscle, this is the type of muscle that we build. They’re called skeletal muscles because they attach all over the skeleton. Skeletal muscles are paired for use, one muscle will move the bone in one direction, while its pair will move the bone in the opposite direction. Unlike cardiac muscles, skeletal muscles can and will contract voluntarily, specifically the millions of tiny striated muscles in the body that are known as sarcomeres.
