The nervous system has its origin in the organism's ontogenesis: it is the “dynamic” element of the complex system; it participates in all the coordinated relationships. Its structure consists in a continuum which operates as a homeostatic system because of its total participation in the system's structure.

CTM calls this dynamic structure "energy" and it develops together with the system’s structural development; it has the function of a dynamic activity, through the EC and the various energetic aspects supporting the organism's interactions inside the homeostatic system. The distribution of the energy requires its participation in every internal or external mutation in the continuum of interactions and relationships generated inside the “closed system”, the organism, of which it is a part.

The energetic system and the organism are atemporal, closed systems, the result of the genetic program.The contemporary development of the system's structure and the energetic dynamics makes it a closed, homeostatic structure that, because of its constitution, is called to participate in the changes of state, consequent of the transformations introduced by the environmental phenomenology inside the organism. Being a “closed system”, it is during the examination of the EC at the pulses that the therapist can observe the variations consequent of the dynamic interaction of the relationships occurring because of the internal and external environmental influences. The physical structure receives continuous information on uncorrelated or non-finalized activities of the biological system.This is the means for realizing the formation and transformation which begins during the embryonic period and continues throughout the lifetime, as is described in CTM physiology and evident at the examination of the EC at the pulses.

It is during the phase of the physical construction of the complex system structure that the harmonization of the temporal rhythm takes place and the dynamics of the EC, accessible through the examination at the pulses, is created.

The peripheral system sends the brain information from the corporeal sensations and the external environment. It has the function of keeping under control all the mechanisms of the body and of proceeding to perform the adaptations required by the various needs of the body: hence it operates by utilizing certain body resources while storing other specific resources.

The immune system (IS) carries out a task ofprimary importance within the energetic dynamics, in relation to the “environmental” parameter.Connected to the endocrine and nervous systems it regulates the behaviour and the interaction of the single metabolic system relative to the environmental and individual biological identity. The extreme IS dependency on the environment’s chaotic dynamics may originate from its function of defence from external assaults and from its function of regulating the inter-exchange of the internal communications with the external world. The IS acts on the corporeal tissues; preserves the memory of preceding situations; favours the tolerance or intolerance of every change within energetic dynamics.

The “somatic language used to communicate environmental information develops during the embryonic period together with nervous system's development; and is activated by receiving the signals coming from the endocrine system.

The IS intervenes when a chaotic, environmental event causes alterations in the biological rhythms because of the influence of the laws of chaos. The quickness and flexibility of the information helps to avoid that chaotic evolutions assume characteristics permanency and become the cause of pathological structural changes within the flow of time.

The IS role consists of maintaining the organism’s internal equilibrium, subjected to internal chaotic perturbations (the energetic dynamics of the organs’ metabolic functions) or external ones (chaotic events, unpredictable factors originating in the external environment). The IS reveals an extreme chaotic sensibility and an extraordinary capacity of adaptability characteristic of the complexity of the dynamic system, inside which the IS finds a role and enters into continuous action. This constant reorganization of the immune system is at the basis of the interaction within the relationships occurring between the endocrine, nervous and the brain's systems.

The brain, conscious or unconscious, automatic, autonomous, awake or asleep, integrates the internal and external environmental changes taking place in the emotional sphere.

The brain and the heart are respectively the Centers of the activities of thinking and of the emotions; in the complex dynamic system, they supply the activities of intelligence, understanding, awareness, consciousness, synchronicity, with which they take part in the creation of an energetic human entity.

The qualities characteristic of the individual's vitality are activated by mental energy: the intelligence. Knowledge, emotivity, affectivity form the Centre of the pluralism of communications.

These psychic activities collect all the voices and messages from the internal and external environment, control them and are controlled by them.Every living system is an “open” system, capable of responses and adaptation to the environment and of self-organization for creating order, cohesiveness, and stability in the flow of time.

This self-organizational adaptation is the result of the elaboration of the information received from the environment.

Through this process is created the awareness of personal interiority and the self-consciousness of personal situations within an environment subjected to continuous movement and change. It is a mechanism of self-reflection and self-consciousness giving access to the knowledge of personal affectivity and emotivity, in order to create a functioning “psychic homeostatic system”. To attain consciousness of personal individuality represents an existential pathway without alternatives: it represents the realization of existence within in time and space; the adult conquest of the perceptive, cognitive world: it is the freedom of free will.

The unpredictable phenomenology of the initial chaotic events, the deterministic chaos, offers the necessary conditions required to transform the linear dynamics into a series of variations with chaotic dynamic evolutions. In these phenomenological events the results of the temporal evolution are different from their initial conditions. The specific action of a series of chaotic variations, consequent of the alterations intervening in the internal and external environmental dynamics causes the assumption of a “typical” behaviour.

The chaotic system adopts the dynamics capable of maintaining the structural organization, by means of its “plasticity”, with which it is in the condition of adopting a series of changes of “state”, according to the environment. In this manner the chaotic system can compensate for the disturbances provoked by “chaotic environmental events” which, “in the flow of time” would provoke structural changes.

The dynamic plasticity ensures the process of self-regulation, through neurophysiological activities. These chaotic behaviours allow for the preservation of the organism's “biological identity”.
