Suppose we are standing or walking and we decide we want to run, how does our thinking finally turns into physical action of running? How does our neurons trigger muscular action ?
In: Biology
The idea for running is generated in the brain first. This happens in the motor cortex of the brain. It send nerve signals down into the spinal cord which then radiates to the muscles of the arms and legs. The spinal cord already has a nerve signal centre that allow for running. Individual muscles are stimulated but in a coordinated manner because of this spinal cord centre. So you don’t have to consciously move each muscle to start running.
I hope that explains a little of what you didn’t know.
