This question is asked so many times. We would like to give you a brief explanation:

A physiotherapist works on muscles, a manual therapist works on the vertebrae and a chiropractor treats the nervous system, joints and muscles. A chiropractor is a specialist in human biomechanics and the nervous system.

The primary difference lays in education: Chiropractic studies are longer and more involved than those of physiotherapy and manual therapy. Chiropractic is a university degree; the others are not.
