MacKenzie zones

German: MacKenzie-Zonen

1 Definition

The MacKenzie zones are projection fields which represent the inner organs onto the muscular system. In cases of stimulation or disease of an inner organ, the correlating MacKenzie zone reacts in form of pain sensitivity or hypersensitivity.

2 Physiology

The phenomenom of the projected pain is explained by convergence of various nerve fibers in the vertebral column which also explains the head's zone of the skin. Visceral afferences of particular organs (e.g. heart) and somatic afferences converge to one neuron inside of the vertebral column. This neuron communicates a disturbance to the central nevous system which is misinterpreted as a pain with its origin in the muscle.
