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 Innate Immunity"
Split Justification: ** Humoral regulation of innate immunity can be fundamentally divided based on whether the regulatory components belong to the highly organized and distinct complement cascade system or comprise other systemic, non-complement chemical messengers. The complement system involves a specific set of interacting proteins that activate sequentially to achieve various immune functions (e.g., direct lysis, opsonization, inflammation). All other systemic innate humoral factors, such as cytokines, acute phase proteins, and circulating antimicrobial peptides, act through distinct mechanisms that do not primarily involve this specific cascade. This distinction provides a mutually exclusive categorization because a humoral factor is either a component of the complement system or it is not, and it is comprehensively exhaustive as all known systemic innate humoral regulators fall into one of these two fundamental categories.
9
From: "Complement System Humoral Regulators"
Split Justification: The complement system consists of a diverse set of humoral proteins. These can be fundamentally divided based on their primary functional role within the cascade: either they directly participate in initiating, propagating, and executing the effector functions of complement (e.g., pathogen lysis, opsonization, inflammation), or their principal role is to control, limit, or inhibit the complement cascade to prevent excessive activation and damage to host tissues. This dichotomy is mutually exclusive, as a complement protein's primary function is either to drive or to restrain the cascade, and it is comprehensively exhaustive, covering all known components of the complement system.
10
From: "Complement Activation and Effector Components"
Split Justification: Complement Activation and Effector Components can be fundamentally divided based on whether their primary functional role is to initiate, amplify, and drive the proteolytic cascade (Complement Cascade Propagators), or to directly mediate the final biological functions of complement such as opsonization, inflammation, or cell lysis (Complement Direct Effectors). The first category includes components that act as recognition molecules, proteases, or critical substrates within the cascade itself, leading to the generation of active fragments. The second category encompasses the bioactive fragments produced by the cascade (e.g., anaphylatoxins, opsonins) and the components that form the terminal membrane attack complex, which directly execute the immune response. This dichotomy is mutually exclusive, as a complement component's predominant function is either to propagate the enzymatic cascade or to directly perform an effector function, and it is comprehensively exhaustive, covering all known complement activation and effector components.
11
From: "Complement Cascade Propagators"
Split Justification: Complement Cascade Propagators can be fundamentally divided based on whether their primary functional role is to initiate a specific complement activation pathway through recognition of triggers and early proteolytic cleavage, or to serve as the structural and catalytic components that are assembled into the C3 and C5 convertase complexes to drive the central amplification loop. The first category includes components such as the C1 complex (C1q, C1r, C1s), MBL/Ficolin-MASP complexes, and Factor D, which detect pathogen-associated patterns or immune complexes and perform the earliest cleavages to establish a pathway. The second category comprises the universal substrates and cofactors (C4, C2, C3, Factor B, Properdin) that form the core enzymatic machinery of the C3 and C5 convertases. This dichotomy is mutually exclusive, as a complement propagator primarily functions either in pathway initiation or in convertase assembly and amplification, and it is comprehensively exhaustive, covering all known complement cascade propagators.
12
From: "Complement Pathway Initiators"
Split Justification: Complement Pathway Initiators can be fundamentally divided based on whether their primary functional role is to detect and bind to specific activating patterns or immune complexes, or to perform the initial proteolytic cleavage that propagates the cascade. The first category includes molecules like C1q, Mannose-binding lectin (MBL), and Ficolins, which serve as pattern recognition receptors by binding to pathogen surfaces or immune complexes. The second category comprises the serine proteases such as C1r, C1s, MASP (MBL/Ficolin-associated serine proteases), and Factor D, which catalyze the early steps of the complement cascade by cleaving specific substrates. This dichotomy is mutually exclusive, as a complement initiator's primary function is either recognition/binding or proteolytic cleavage, and it is comprehensively exhaustive, covering all known complement pathway initiators involved in either detection or the very first enzymatic steps.
