From: "Human Potential & Development."
Split Justification: Development fundamentally involves both our inner landscape (**Internal World**) and our interaction with everything outside us (**External World**). (Ref: Subject-Object Distinction)..
2
From: "Internal World (The Self)"
Split Justification: The Internal World involves both mental processes (**Cognitive Sphere**) and physical experiences (**Somatic Sphere**). (Ref: Mind-Body Distinction)

From: "Somatic Sphere"
Split Justification: The Somatic Sphere encompasses all physical aspects of the self. These can be fundamentally divided based on whether they are directly accessible to conscious awareness and subjective experience (e.g., pain, touch, proprioception) or whether they operate autonomously and beneath the threshold of conscious perception (e.g., heart rate, digestion, cellular metabolism). Every bodily sensation, state, or process falls into one of these two categories, making them mutually exclusive and comprehensively exhaustive.
4
From: "Autonomic & Unconscious Somatic Processes"
Split Justification: ** All unconscious somatic processes are fundamentally regulated through either the dedicated neural pathways of the autonomic nervous system or through the intrinsic, self-regulating mechanisms of other physiological systems (e.g., endocrine, immune, cellular, local tissue systems). These two categories comprehensively cover all autonomous and unconscious bodily functions and are mutually exclusive in their primary regulatory mechanism.
5
From: "Non-Neural Autonomous Physiological Processes"
Split Justification: Non-neural autonomous physiological processes can be fundamentally divided based on the scale and transport mechanism of their primary regulatory signals. One category encompasses regulation achieved through chemical messengers (such as hormones, circulating cytokines, or antibodies) that are transported via body fluids (blood, lymph, interstitial fluid) to exert widespread or distant effects throughout the organism. The other category comprises processes that are intrinsic to the cell or local tissue itself, relying on internal cellular mechanisms (e.g., metabolism, gene expression), direct physical or chemical responses within the immediate tissue environment, or paracrine/autocrine signaling confined to the immediate vicinity, without requiring systemic transport for their primary regulatory action. These two categories are mutually exclusive, as a regulatory mechanism either relies on systemic transport for its primary action or it does not, and together they comprehensively cover all non-neural autonomous physiological processes.
6
From: "Cellular and Local Intrinsic Regulation"
Split Justification: Cellular and Local Intrinsic Regulation encompasses all non-systemic, non-neural physiological processes that are intrinsic to a cell or its immediate local tissue environment. These processes can be fundamentally divided based on whether they operate strictly within the confines of a single cell (Intracellular Regulation, covering internal cellular mechanisms like metabolism, gene expression, and autocrine signaling) or whether they involve interactions between multiple adjacent cells or with the immediate non-cellular components of the local tissue environment (Local Intercellular and Tissue Microenvironment Regulation, covering paracrine signaling, juxtacrine signaling, and regulation of the extracellular matrix and local physiochemical conditions). These two categories are mutually exclusive, as a regulatory process is either contained within a single cell or involves elements external to it but still within the local vicinity, and together they comprehensively cover all forms of non-systemic, non-neural intrinsic regulation.
7
From: "Local Intercellular and Tissue Microenvironment Regulation"
Split Justification: Local Intercellular and Tissue Microenvironment Regulation can be fundamentally divided based on whether the primary regulatory mechanism involves direct physical contact or connection between adjacent cells, or whether it relies on signals or influences mediated by the extracellular matrix and interstitial fluid. The former category encompasses mechanisms requiring direct cell-to-cell physical interaction (e.g., juxtacrine signaling, gap junctions, adherens junctions). The latter category includes regulation via chemical messengers that diffuse through the interstitial fluid to nearby cells (e.g., paracrine signaling), as well as the influence of the extracellular matrix's physical and chemical properties and local physiochemical conditions (e.g., pH, oxygen levels) on cellular function. These two categories are mutually exclusive, as a regulatory interaction either fundamentally requires direct cellular contact or it does not, and together they comprehensively cover all forms of local intercellular and tissue microenvironment regulation described by the parent node.
8
From: "Extracellular Factor-Mediated Local Regulation"
Split Justification: ** Extracellular Factor-Mediated Local Regulation can be fundamentally divided based on whether the primary regulatory mechanism involves discrete, soluble signaling molecules that diffuse through the interstitial fluid to interact with cells, or whether it stems from the inherent physical and chemical properties of the extracellular matrix itself and the general physiochemical conditions of the interstitial fluid. The former category includes mechanisms like paracrine signaling, where specific chemical messengers act over short distances. The latter encompasses regulatory influences from matrix stiffness, adhesion sites, local pH, oxygen levels, and the overall composition of the extracellular matrix. These two categories are mutually exclusive, as a regulatory factor is either a mobile, soluble signal or a characteristic of the matrix/bulk fluid environment, and together they comprehensively cover all forms of extracellular factor-mediated local regulation.
9
From: "Regulation by Diffusible Signaling Molecules"
Split Justification: ** All local intercellular regulation mediated by diffusible signaling molecules fundamentally achieves its effect by either primarily promoting (e.g., stimulating, activating, enhancing) or primarily suppressing (e.g., inhibiting, deactivating, reducing) the activity or function of target cells. These two categories represent the exhaustive set of primary functional outcomes of such signaling, and a given regulatory event, when considered for its dominant effect on a specific target process, is mutually exclusive in its promotive or suppressive action.
10
From: "Regulation via Suppressive Diffusible Signals"
Split Justification: All local intercellular regulation via suppressive diffusible signals fundamentally achieves its effect by either primarily influencing the internal machinery of the target cell to reduce its activity or alter its functional state, or by primarily interfering in the extracellular space with other activating signals or their reception by the target cell. The former category includes signals that initiate intracellular cascades leading to decreased metabolism, inhibited proliferation, or induced apoptosis. The latter category includes signals that neutralize or degrade activating ligands in the interstitial fluid, or that physically block or antagonize target cell receptors for activating signals. These two categories are mutually exclusive, as a suppressive diffusible signal's primary site of action is either within the target cell or external to it by modulating the activating microenvironment, and together they comprehensively cover all mechanisms of regulation via suppressive diffusible signals.
11
From: "Regulation via Suppressive Signals Acting on Extracellular Ligands or Receptors"
Split Justification: Regulation via Suppressive Signals Acting on Extracellular Ligands or Receptors involves mechanisms where a suppressive signal interferes with receptor activation. This interference can fundamentally occur by primarily targeting the extracellular ligand itself (e.g., degrading it, sequestering it, or rendering it inactive), or by primarily targeting the receptor directly (e.g., blocking its binding site, inducing an inactive conformation, or promoting its internalization). These two categories are mutually exclusive, as the primary site of action for the suppressive signal is either the ligand or the receptor, and together they comprehensively cover all forms of regulation described by the parent node.
12
From: "Regulation by Signals Targeting Receptors Directly"
Split Justification: Regulation by Signals Targeting Receptors Directly encompasses all mechanisms where a suppressive diffusible signal acts directly on a target cell's receptor. These mechanisms can be fundamentally divided based on whether the signal primarily prevents the receptor from being activated by its intended ligand (e.g., by blocking binding sites or inducing inactive conformations) while the receptor remains at the cell surface, or whether the signal primarily decreases the overall capacity for signal transduction by reducing the effective number of functional receptors (e.g., by promoting internalization, degradation, or intrinsic desensitization). These two categories are mutually exclusive, as a suppressive signal's dominant effect on the receptor is either to inhibit its immediate activation or to diminish its sustained signaling capacity through changes in its presence or intrinsic responsiveness, and together they comprehensively cover all forms of direct receptor targeting for suppression.
