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)
3
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: "Autonomic Neural Regulation"
Split Justification: Autonomic neural regulation is fundamentally divided into the sympathetic nervous system, which primarily prepares the body for action and stress responses, and the parasympathetic nervous system, which primarily facilitates rest, digestion, and energy conservation. These two branches constitute the entirety of the autonomic nervous system, operating with largely opposing effects on target organs, making them mutually exclusive and comprehensively exhaustive for covering all aspects of autonomic neural regulation.
6
From: "Sympathetic Neural Regulation"
Split Justification: Sympathetic neural regulation exerts its effects through two distinct and exhaustive primary output mechanisms: either by postganglionic neurons directly releasing neurotransmitters at target cells, or by preganglionic neurons stimulating the adrenal medulla to secrete catecholamine hormones into the bloodstream for systemic action. These two mechanisms are mutually exclusive in their method of signal delivery and collectively account for all sympathetic regulatory processes.
7
From: "Direct Sympathetic Neurotransmission"
Split Justification: All direct sympathetic neurotransmission by postganglionic neurons fundamentally involves the release of one of two primary neurotransmitters: norepinephrine (which mediates the vast majority of sympathetic effects) or acetylcholine (which is released by sympathetic fibers innervating sweat glands and a few other specific targets). These two categories are mutually exclusive, as a given neuron releases one or the other, and comprehensively exhaustive, covering all known instances of direct sympathetic neurotransmission.
8
From: "Noradrenergic Direct Sympathetic Neurotransmission"
Split Justification: All noradrenergic direct sympathetic neurotransmission exerts its physiological effects by binding to and activating adrenergic receptors on target cells. These receptors are fundamentally divided into two major classes: alpha (α) adrenergic receptors and beta (β) adrenergic receptors. These two receptor classes initiate distinct intracellular signaling cascades and mediate diverse, often opposing, physiological responses, making them mutually exclusive at the level of their mechanistic action. Together, alpha and beta adrenergic receptors comprehensively account for all known mechanisms by which norepinephrine mediates direct sympathetic effects.
9
From: "Alpha-Adrenergic Receptor Mediated Noradrenergic Transmission"
Split Justification: Alpha-adrenergic receptors are fundamentally classified into two major subtypes: alpha-1 (α1) and alpha-2 (α2) adrenergic receptors. These two subtypes are distinguished by their molecular structure, signal transduction pathways, and their characteristic physiological roles and locations (e.g., α1 receptors are primarily postsynaptic and often mediate vasoconstriction, while α2 receptors can be pre- or postsynaptic and often inhibit neurotransmitter release or mediate other effects). This classification is mutually exclusive, as any given alpha-adrenergic receptor is either an α1 or an α2 subtype, and comprehensively exhaustive, as all known alpha-adrenergic receptor mediated noradrenergic transmission is accounted for by these two receptor types.
10
From: "Alpha-1 Adrenergic Receptor Mediated Noradrenergic Transmission"
Split Justification: ** Alpha-1 adrenergic receptors are fundamentally categorized into three distinct molecular subtypes: α1A, α1B, and α1D, each with unique genetic sequences, tissue distributions, and pharmacological properties. To create a mutually exclusive and comprehensively exhaustive binary split for Alpha-1 adrenergic receptor mediated noradrenergic transmission, the well-characterized Alpha-1A subtype is distinguished from the remaining Alpha-1 receptor subtypes (Alpha-1B and Alpha-1D), which together account for all other forms of Alpha-1 mediated noradrenergic transmission.
11
From: "Alpha-1A Adrenergic Receptor Mediated Noradrenergic Transmission"
Split Justification: Alpha-1A adrenergic receptor activation elicits a diverse range of cellular and physiological responses. These responses can be fundamentally divided based on whether they involve the active shortening or tightening of muscle cells (contractile responses, such as vasoconstriction, smooth muscle contraction in the prostate or bladder, and cardiac inotropy) or if they pertain to other cellular processes (non-contractile responses, such as cellular growth, hypertrophy, or metabolic regulation). This distinction is mutually exclusive, as any specific physiological outcome mediated by α1A receptors is either contractile or non-contractile, and comprehensively exhaustive, covering all known effects of Alpha-1A adrenergic receptor mediated noradrenergic transmission.
12
From: "Alpha-1A Adrenergic Receptor Mediated Non-Contractile Responses"
Split Justification: Alpha-1A adrenergic receptor mediated non-contractile responses can be fundamentally divided based on whether they involve a change in the physical structure, size, or number of cells (e.g., cellular hypertrophy, hyperplasia, or apoptosis) or whether they involve an alteration in the ongoing functional activity, signaling, or metabolic state of existing cells without directly changing their physical form. These two categories are mutually exclusive, as any specific non-contractile response is either primarily a structural/morphological adaptation or a functional/metabolic modulation, and they are comprehensively exhaustive, accounting for all known non-contractile effects of Alpha-1A adrenergic receptor activation.
