Effect Upon Organs
Each organ is but an aggregation of cells of some special type or kind. Nerve Impingement usually involves either a whole nerve trunk or many of its fibres and thus weakens either the entire organ or many of its cells and increases or diminishes its special function. Some organs are innervated by more than one nerve and may be injured only in part by a localized impingement.
Alteration of the action of one organ often tends to affect the entire body, as in subluxation of the fourth Dorsal interfering with the nerve supply to the liver the secretion of bile becomes altered in character or quantity and the entire system suffers, through deranged digestion, from this alteration in a necessary secretion. Every disease presents symptoms only indirectly referable to the organ which is primarily affected and the problem of the diagnostician is to so discriminate between direct and indirect symptoms as to be able to locate disease.
