Basic Human Anatomy: The Nervous System

The human systems that require further learning consist of; the nervous, skeletal, muscular, cardiorespiratory, digestive, and endocrine system. These systems work together in complex ways to function, balance, and grow your body properly.

I’ll give you a brief overview, but I highly encourage you to investigate the body further and learn how all systems function to maintain optimal health on your own. I do not claim to be an expert in any one of these systems. Like you, I am constantly learning and I will try my best to translate a very brief description of each system of the body.

First the nervous system is about as complex as you can get. Our “super computer,” a.k.a. the brain, controls all that you do whether it’s voluntary or involuntary, with a few auto-reflexes aside. Your brain communicates through nerves which transmits information back and forth to your muscles, bones, and organs.

Your brain has over 100 billion neurons, commonly known as brain cells, where they fire information from one to the next at lightning speed. Your brain can connect through your spinal cord, down to the muscles that control your toes and back to your brain, then back to your toes before you can even begin to mouth the word “toes.” That’s fast.

Your brain has an excellent, automatic-muscular-memory bank which responds to external factors more efficiently as they repeat themselves. This gives us the power to adapt and overcome external forces as we train through our repetitions.

In simple terms, our brain controls our body and the more we move, the quicker our muscles respond automatically. The less we move, the slower our response and the weaker they become.
