020117 Neurons and sarcomeres
In the neuromuscular system, the neuron provides the link between the nervous system and the muscles. Without this interaction, no activity would take place.
The sarcomere is the smallest and most basic muscle unit. It contains all of the contractile and regulatory mechanisms necessary to function as part of the muscular system.
Muscle fibers contain hundreds to thousands of sarcomere. The muscles themselves are made up of numerous fibers.
Listening to your body
Your body tells you what is going on…if you pay attention to it. Sometimes it is obvious; a muscle tweak or worse, an injury. Often it is just a feeling that you can’t quite describe or put your finger on. In the latter case, it’s the status of your homeostasis being disrupted. You know it on a subconscious, internal sensation, level.
In order to recognize these inputs, you must practice paying attention to them. This observational attitude has to be developed. It is not easy, but can be done with practice. Notice how your body responds to different stimulate, or how the bar feels in your hand as you lift. How does it feel or what is your body doing during these activities that are creating these sensations?
With practice, you will become more and more aware of these ambiguous signs from within your body. You’ll be amazed at the detail provided by the movement and postures that take place during the exercise.
Learn to listen to these vague signals. You will be the recipient of valuable lessons and information. This will enable you to grow stronger and more powerful, both in body and mind.
