Today’s Chiropractors study the basic human sciences of biology and become experts in the sciences of human anatomy, physiology, and neurology. This is done through doctoral level post-graduate programs in college/university campuses throughout the world. Much like medical doctorate programs, where students study the basic human sciences then pharmacology (study of drugs), and then go to practice on live people in a clinic setting, Chiropractors do much the same. The exception is, instead of focusing on the study of drugs, the chiropractic student studies biomechanics and the techniques of examination, assessment, and adjustment of the spine for the proper function of the nervous system and musculoskeletal function.
These are the nerves that communicate information about your environment to your brain. Your body uses this type of nerve to communicate that it is hot outside so you can start sweating to cool yourself down. Without this function your body would not be able to perceive sensations that your body experiences and would therefore not be able to react to external environmental conditions or internal body conditions.
These are the nerves that communicate instructions to your muscles in order to coordinate movement. Your body uses this type of nerve to optimize kinesthetic performance. Optimum function of this nerve type is critical for athletes. Without this function your body will not be able to move in a coordinated way or hold itself appropriately.
This nerve type can be referred to as the Organ Nerve, because that is exactly what it affects. This nerve is responsible for communicating with all of your blood vessels, heart, glands, and has control over the sympathetic and parasympathetic systems (fight or flight). Optimal function of these nerves is critical in order to have health. Needless to say without these nerves you will not be able to sustain life.
True vitality of life can only be achieved when all three of these nerve types are functioning optimally.
