Life is intelligent action, movements guided by intelligence. Impulses are thoughts in transmission over the nervous system. Vital makes possible organic functions, the power of motion and feeling. The amount of tension depends upon the relative position of the osseous frame, the neuroskeleton, the skeleton of the vertebrates.
Health is a condition wherein all the functions are performed with a normal amount of force.
Disease is an existence in which the action of an organ or organs are improperly performed. Death is a situation wherein action has ceased to be controlled by intelligence. The state of dissolution, or the act of a rolling stone, is not that of intelligence. Inflammation is a condition in which some local portion exhibits a higher temperature than any other, including the blood. Do not forget, in order to disturb functions, there must be in-ordinate nerve tension, also, a change in heat production.
