Think about how the body knows to heal a simple cut. Its knowlede of how to organise the healing process from memory is inborn and we couldn't stop it even if we tried. A dead body has all the parts but won't heal like this at all.
INNATE: Inborn, Inherent, Within, Instinctive.
INTELLIGENCE: Knowledge, Organisation, Memory
No matter what you call it, living things have it and dead things don't. It is a force that animates, adds life, grows, organises and evolves. Each cell has it, each organ has it, every living thing has it. Chiropractors call this Force Innate Intelligence.
The brain, spinal cord and nerves are connected directly or indirectly to every cell, tissue, organ and structure within the body. This is the communication control system which allows the body to respond in an intelligent and co-ordinated way to external and internal events.
A subluxation is any tension, twist or compression within the nervous system that interferes with proper nerve function. It can have delitarious effects on movement, repair, co-ordination of all bodily and psychological functions, and hence on health and wellbeing.
An adjustment is a specific force introduced into the spine that corrects a subluxation and improves or restores normal nervous system function. Hence your bodies innate healing properties are activated. The body is better able to help istelf heal. There are many different types of adjustment.
