The Major Premise of Upper Cervical Care is that there is a subluxation (vertebral misalignment with nerve interference) in the upper cervical spine interfering with the expression of life in the body. Throughout the body, nerve fibers travel from the brain down the spinal cord to every tissue, organ and cell of the body. It is these nerve fibers that carry mental impulse from the brain which nourish the body and allow for proper communication from the brain to the body and back to the brain again. Misalignments throughout the spine can interfere with these messages causing decreased signaling throughout the body depending on which nerve root is compressed and which part of it is interfered with as it exits the spine. A nerve, although impinged, will still fire to the extent it can into the body and the end organ it innervates.
