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: "Systemic Humoral Regulation"
Split Justification: Systemic humoral regulation is fundamentally mediated by either hormones, which are chemical messengers predominantly secreted by endocrine glands to regulate diverse physiological processes like metabolism, growth, and reproduction; or by immune factors (such as cytokines and antibodies), which are chemical messengers primarily produced by immune cells to coordinate defense, inflammation, and immune surveillance. These two categories represent distinct yet comprehensive regulatory systems, ensuring that all systemic, non-neural chemical signaling is covered, with their primary origins and functional domains being mutually exclusive.
7
From: "Immune System Humoral Regulation"
Split Justification: Immune System Humoral Regulation is fundamentally distinguished based on whether the regulatory chemical messengers mediate responses belonging to the innate or adaptive branches of immunity. Innate immune humoral regulation involves factors (e.g., complement proteins, acute phase proteins, certain cytokines) that provide immediate, non-specific defense. Adaptive immune humoral regulation involves factors (e.g., antibodies, specific cytokines from lymphocytes) that enable highly specific, memory-based responses. This dichotomy is mutually exclusive because a given humoral regulatory mechanism's primary role and context is either non-specific or specific, and comprehensively exhaustive as all systemic humoral regulation within the immune system falls under one of these two fundamental types of immune response.
8
From: "Humoral Regulation of Adaptive Immunity"
Split Justification: Humoral Regulation of Adaptive Immunity is fundamentally achieved through two distinct mechanisms involving soluble factors. One mechanism involves antibodies (immunoglobulins), which are secreted by plasma cells and directly mediate adaptive immune responses by binding to specific antigens, leading to neutralization, opsonization, or complement activation, thereby regulating pathogen activity or toxin effects. The other mechanism involves cytokines, which are secreted signaling proteins produced by various immune cells (including T cells and B cells) that act humorally to regulate the proliferation, differentiation, and effector functions of adaptive immune cells themselves, thereby coordinating and modulating the adaptive response. These two categories are mutually exclusive in their primary molecular identity and direct regulatory targets (pathogens/toxins vs. immune cells), and together they comprehensively cover the spectrum of humoral regulation within the adaptive immune system.
9
From: "Antibody-Mediated Adaptive Regulation"
Split Justification: All antibody-mediated adaptive regulation fundamentally occurs through one of two mechanisms: either antibodies directly bind to antigens and interfere with their biological function (e.g., blocking receptor binding, precipitation, agglutination), or they bind to antigens and subsequently recruit other immune effectors (e.g., phagocytes, NK cells, complement proteins, mast cells) through their Fc region to eliminate the antigen or antigen-bearing cell. These two mechanisms are mutually exclusive in their primary mode of action and comprehensively cover all known roles of antibodies in adaptive immunity.
10
From: "Fc-Mediated Effector Recruitment"
Split Justification: Fc-mediated effector recruitment fundamentally proceeds through two distinct pathways: either the antibody's Fc region binds to specific Fc receptors located on the surface of various immune effector cells (e.g., phagocytes, NK cells, mast cells), thereby engaging those cells' functions; or the antibody's Fc region binds to the C1q component of the classical complement pathway, initiating a soluble cascade of proteins. These two mechanisms are mutually exclusive in their direct target (cell surface receptor vs. soluble protein complex) and comprehensively cover all known forms of Fc-mediated effector recruitment.
11
From: "Fc-Mediated Complement Activation"
Split Justification: Fc-mediated complement activation fundamentally initiates the classical pathway by activating the C1 complex, where the activated C1s enzyme subsequently performs two distinct and indispensable proteolytic cleavages: one on the C4 protein and another on the C2 protein. These two enzymatic actions are mutually exclusive as they target different substrates, yet together they comprehensively represent the immediate and direct molecular steps of the Fc-mediated complement activation phase, leading to the formation of the classical C3 convertase.
12
From: "C1s-Catalyzed Cleavage of C2"
Split Justification: The proteolytic action of C1s on the C2 protein fundamentally results in the generation of two distinct polypeptide fragments, C2a and C2b. These two fragments are mutually exclusive in their molecular identity and together represent the comprehensive set of direct products derived from this specific cleavage event.
