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: "Intracellular Regulation"
Split Justification: ** Intracellular Regulation encompasses all non-systemic, non-neural physiological processes contained within a single cell. These processes can be fundamentally divided based on whether they primarily involve the control of the cell's inherent genetic and epigenetic programming, its interpretation of and response to various internal and external signals, and its overall functional identity (e.g., gene expression, protein synthesis, cell differentiation, stress responses that modify cell behavior), or whether they primarily involve the dynamic management of the cell's energy and material resources, and the maintenance of its internal physical and chemical stability (e.g., metabolic pathways, nutrient uptake, waste removal, ion homeostasis, pH and redox regulation). These two categories are mutually exclusive, as a regulatory mechanism's primary focus is either on informational control and execution or on the management of biochemical processes and physical state, and together they comprehensively cover all forms of intracellular regulation.
8
From: "Regulation of Cellular Programming and Adaptive Response"
Split Justification: Regulation of Cellular Programming and Adaptive Response can be fundamentally divided based on whether the mechanisms establish and maintain the cell's long-term functional identity and inherited potential, or whether they govern its immediate and flexible responses to current internal and external signals, dynamically altering gene expression and protein activity within that established identity. The first category (Cell Lineage Commitment and Epigenetic Memory) involves the stable programming that defines what a cell *is* and *can become* (e.g., cell differentiation, maintenance of epigenetic marks). The second category (Dynamic Transcriptional and Signal Responses) involves the real-time interpretation of cues and the adaptive execution of genetic information (e.g., signal transduction, stress responses, inducible gene expression). These two categories are mutually exclusive, as a regulatory process is either contributing to the cell's stable, inherited program or to its dynamic, context-specific adaptation, and together they comprehensively cover all forms of cellular programming and adaptive response.
9
From: "Regulation of Cell Lineage Commitment and Epigenetic Memory"
Split Justification: ** Regulation of Cell Lineage Commitment and Epigenetic Memory encompasses two fundamentally distinct but interconnected sets of processes. One category includes the regulatory mechanisms that govern the initial specification and irreversible determination of a cell's developmental path and functional identity, leading to a committed cell lineage (e.g., interpreting developmental cues to become a specific cell type). The other category comprises the regulatory mechanisms responsible for ensuring the long-term stability of this established cell identity over time and its faithful transmission to daughter cells during proliferation, thereby creating the cell's epigenetic memory and resistance to dedifferentiation or transdifferentiation. These two categories are mutually exclusive, as a regulatory mechanism's primary function is either to actively *set* a cell's fate or to *preserve and propagate* that established fate, and together they comprehensively cover all aspects of cell lineage commitment and epigenetic memory.
10
From: "Maintenance and Heritability of Cell Identity"
Split Justification: Maintenance and Heritability of Cell Identity can be fundamentally divided based on whether the mechanisms involve the ongoing, active processes that ensure a cell's established identity remains stable and resistant to change throughout its lifespan (Continuous Intrinsic Identity Preservation), or whether they involve the specific molecular machinery responsible for faithfully copying and distributing this identity-defining epigenetic information to daughter cells during DNA replication and cell division (Replication-Coupled Epigenetic Transmission). These two categories are mutually exclusive, as one focuses on the active stabilization of identity within a cell's lifetime, and the other on its accurate propagation to new cells during division, and together they comprehensively cover all aspects of cell identity maintenance and heritability.
11
From: "Replication-Coupled Epigenetic Transmission"
Split Justification: Replication-Coupled Epigenetic Transmission can be fundamentally divided based on the distinct molecular substrates and mechanisms involved in perpetuating epigenetic information during DNA replication and cell division. One category encompasses the faithful re-establishment of DNA methylation patterns on newly synthesized DNA strands, ensuring the transmission of this chemical mark directly on the genetic material. The other category comprises the assembly of parental and newly synthesized histones onto daughter DNA molecules and the subsequent re-establishment of specific histone modification patterns and higher-order chromatin structures, thereby propagating information encoded in nucleoprotein complexes. These two categories are mutually exclusive, as they involve distinct molecular components and enzymatic pathways, and together they comprehensively cover the primary, direct molecular mechanisms of epigenetic information inheritance coupled to genome replication.
12
From: "Replication-Coupled DNA Methylation Inheritance"
Split Justification: Replication-coupled DNA methylation inheritance fundamentally involves two distinct sets of mechanisms. One set focuses on the accurate recognition and interpretation of the pre-existing methylation patterns on the parental DNA strand, which serves to recruit and position the maintenance machinery at the correct genomic loci. The second set encompasses the subsequent enzymatic activity that adds methyl groups to the corresponding unmethylated cytosines on the newly synthesized daughter DNA strand, thereby replicating the pattern. These two categories are mutually exclusive, as one process involves sensing the template information and guiding the machinery, while the other involves the actual chemical modification, and together they comprehensively cover the molecular steps required for perpetuating DNA methylation during DNA replication.
