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 Regulatory and Inhibitory Proteins"
Split Justification: Complement regulatory and inhibitory proteins fundamentally achieve their control either by modulating complement activation in the circulating fluids (e.g., plasma, lymph) or by protecting host cells directly through their presence on cell surfaces. This distinction based on their primary functional location—fluid-phase versus cell-surface—is mutually exclusive, as a protein's predominant site of action for complement regulation is distinctively one or the other, and comprehensively exhaustive, encompassing all known categories of complement regulatory and inhibitory proteins.
11
From: "Membrane-Bound Complement Regulatory Proteins"
Split Justification: Membrane-bound complement regulatory proteins fundamentally exert their control at distinct stages of the complement cascade. One category primarily acts upstream by inhibiting the formation or stability of C3 and C5 convertases or facilitating the inactivation of C3b and C4b, thereby preventing complement amplification. The other category acts downstream by directly interfering with the assembly of the Membrane Attack Complex (MAC), preventing cellular lysis. These two functional groups represent mutually exclusive points of intervention within the cascade, as a protein's predominant regulatory action targets either the upstream amplification steps or the terminal lytic pore formation, and together they comprehensively cover all known membrane-bound complement regulatory mechanisms.
12
From: "Proteins Inhibiting Membrane Attack Complex (MAC) Formation"
Split Justification: MAC formation fundamentally requires the successful insertion of C8 into the C5b-7 complex on the host cell membrane, followed by the polymerization of multiple C9 molecules to create the lytic pore. These two processes represent distinct, sequential stages where membrane-bound regulatory proteins can intervene. Mechanisms that block C8 insertion fundamentally prevent the establishment of the C5b-8 complex required for C9 recruitment, while mechanisms that block C9 polymerization act downstream to prevent the final pore formation. These two categories of mechanisms are mutually exclusive in their primary point of intervention and comprehensively cover how membrane-bound proteins inhibit MAC formation.
