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 Extracellular Matrix Properties and Local Bulk Conditions"
Split Justification: Regulation by Extracellular Matrix Properties and Local Bulk Conditions can be fundamentally divided based on whether the primary regulatory mechanism stems from the physical attributes of the matrix and its architecture (e.g., stiffness, topography, porosity, mechanical forces, density of adhesion sites) or from the chemical identity and concentration of its constituents and the general physiochemical state of the local environment (e.g., pH, oxygen levels, ion concentrations, nutrient availability, specific molecular makeup of the ECM components). These two categories are mutually exclusive, as a regulatory influence is primarily either physical/structural or chemical, and together they comprehensively cover all forms of regulation stemming from the inherent properties of the ECM and local bulk conditions.
10
From: "Regulation by Physical and Structural Properties of the Extracellular Matrix"
Split Justification: The physical and structural properties of the ECM that regulate cell function can be fundamentally divided based on whether they describe the inherent, relatively stable material characteristics and structural organization of the matrix itself, or whether they relate to the dynamic application of mechanical forces to the matrix and the active processes that lead to its structural modification. The former category encompasses properties like matrix stiffness, elasticity, porosity, and fiber alignment, which represent the baseline physical state and architecture. The latter category includes regulatory influences from applied external forces (e.g., tension, compression, shear), cell-generated traction forces, and the continuous processes of ECM synthesis, degradation, and restructuring. These two categories are mutually exclusive, as a regulatory influence is either an inherent characteristic of the matrix's physical composition and structure or a dynamic process involving forces or structural change, and together they comprehensively cover all forms of regulation stemming from the physical and structural properties of the ECM.
11
From: "Regulation by Intrinsic Material Properties and Static Architecture of the ECM"
Split Justification: The parent node, "Regulation by Intrinsic Material Properties and Static Architecture of the ECM," explicitly combines two distinct types of physical and structural attributes. This split separates these two fundamental aspects: one focusing on the inherent physical and mechanical characteristics of the ECM's bulk material (e.g., stiffness, elasticity, viscosity, density), and the other focusing on its static structural organization and geometric features (e.g., porosity, fiber alignment, surface roughness, specific topographical patterns, and the spatial presentation of adhesion sites). These two categories are mutually exclusive, as a regulatory influence is primarily attributable to either the material's inherent properties or its geometric arrangement, and together they comprehensively cover all forms of regulation stemming from the intrinsic material properties and static architecture of the ECM.
12
From: "Regulation by Intrinsic Material Properties of the ECM"
Split Justification: The intrinsic material properties of the ECM, which influence cell function, can be fundamentally divided based on whether they describe the material's response to applied mechanical forces and deformation (e.g., stiffness, elasticity, viscoelasticity) or whether they describe other inherent physical characteristics of the bulk material that are not primarily mechanical (e.g., density, specific gravity, permeability to solutes, electrical conductivity, thermal properties). These two categories are mutually exclusive, as a material property is either primarily mechanical or it is not, and together they comprehensively cover all intrinsic material properties of the ECM.
