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)
3
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: "Contact-Dependent Intercellular Regulation"
Split Justification: ** All contact-dependent intercellular regulation mechanisms fundamentally establish either a direct physical channel connecting the cytoplasms of adjacent cells, allowing for the passage of ions and small molecules, or they involve interactions exclusively at the cell surface through membrane-bound molecules or structural complexes that do not create cytoplasmic continuity. These two categories are mutually exclusive, as a mechanism either provides direct cytoplasmic connection or it does not, and together they comprehensively cover all forms of direct cell-to-cell contact regulation.
9
From: "Surface-Mediated Contact Regulation"
Split Justification: ** Surface-mediated contact regulation fundamentally occurs via two distinct mechanisms: either through specific molecular recognition events where membrane-bound ligands bind to corresponding receptors on an adjacent cell, directly initiating intracellular signal transduction pathways, or through the formation of stable physical connections and seals between cells that provide structural integrity or create barriers. These two mechanisms are mutually exclusive, as the primary mode of regulation is either signal initiation or physical linkage/barrier creation, and together they comprehensively cover all forms of surface-mediated contact regulation.
10
From: "Physical Adhesion and Barrier Formation"
Split Justification: ** Physical adhesion and barrier formation mechanisms fundamentally serve two distinct primary functions at the cell surface: either to provide strong mechanical attachment and structural integrity between adjacent cells, often by linking their cytoskeletons (e.g., adherens junctions, desmosomes), or to create impermeable seals that regulate paracellular transport and maintain distinct fluid compartments (e.g., tight junctions). A specific mechanism's primary physical role is clearly characterized as either providing mechanical linkage or forming a barrier, making these functions mutually exclusive, and together they comprehensively cover all forms of direct cell-to-cell physical adhesion and barrier formation.
11
From: "Sealing and Barrier Formation"
Split Justification: ** Within the domain of "Sealing and Barrier Formation," mechanisms fundamentally differentiate based on whether their primary function is to establish a highly restrictive, nearly impermeable barrier that prevents significant paracellular movement of solutes and water, or to create a barrier that actively and selectively regulates the passage of specific ions and small molecules between cells. These two categories are mutually exclusive, as a sealing mechanism is primarily designed either for general occlusion or for specific permeability modulation, and together they comprehensively cover all forms of cellular sealing and barrier functions.
12
From: "Formation of Permeability-Modulating Cellular Barriers"
Split Justification: ** Permeability-modulating cellular barriers fundamentally achieve their function either by establishing highly selective, protein-formed channels within the paracellular space that allow the regulated passage of specific ions or small molecules, or by dynamically adjusting the overall physical tightness and pore size of the junctional complex, which modifies the passage of a broader range of solutes and water. These two mechanisms are mutually exclusive in their primary mode of operation (specific channel vs. general tightness adjustment) and comprehensively cover the ways such barriers modulate permeability.
