Dr. Bruce Lipton pointed out that if you were the size of an individual cell so you could see your body from that perspective, you would see yourself, not as a single entity, but as a bustling community of more than 50 trillion individual cells. Most of the cell’s structures are referred to as organelles, which are its ‘miniature organs,’ suspended within a jelly-like cytoplasm. Organelles are the functional equivalents of the tissues and organs of your own body. Each nucleus-containing cell (eukaryote) possesses the functional equivalent of your nervous, digestive, respiratory, excretory, endocrine, skeletal, circulatory, skin, and immune systems. Groups of specialized cells that form the tissues and organs of the nervous system, are concerned with reading and responding to environmental stimuli. The nervous system’s job is to perceive the environment and coordinate the behavior of all the cells in the vast cellular community.
