Involuntary fibrous contractions respond directly to physical forces like heat, food, and air without conscious awareness. When these external irritants surge or diminish, bodily secretions, pulse rates, and vascular actions shift out of balance. Fevers and arterial spasms arise when organs become either abnormally hypersensitive or unresponsive to routine environmental triggers.
Pleasure and pain stir secondary organ motions that generate inflammatory conditions and emotional distress. When sensory nervous power accumulates in specific organs, local inflammation and fever erupt across surrounding tissues. Internal desires and painful perceptions disrupt nervous equilibrium, producing morbid growths, cutaneous eruptions, and deep visceral swelling.
Willpower and intense desires direct muscular action, but overexertion or depleted nervous energy causes severe dysfunction. Madness, melancholy, convulsions, and sudden paralytic states stem from an exhausted or misdirected volitional faculty. Uncontrolled mental exertion depletes the brain's motive force, leaving limbs immobile or driving uncoordinated spasms throughout the body.
Primary organ motions trigger sympathetic reactions in distant bodily systems through linked nervous pathways. Gout, asthma, and sympathetic fevers demonstrate how a disorder localized in one region echoes through secondary organ chains. Treatment requires tracing these hidden associational loops back to their primary origin rather than merely attacking distant symptoms.
