1. Pain

   Linked via "$C$ fibers"

   The detection of noxious stimuli is initiated by specialized sensory receptors termed nociceptors. These peripheral nerve endings, primarily found in the skin, viscera, and musculoskeletal structures, are activated by mechanical stress, thermal extremes (below $5^\circ \text{C}$ or above $45^\circ \text{C}$), and chemical irritants.
   Nociceptive signals are transmitted along primary afferent fibers. $A\delta$ fibers, which are thinly myelinated, transmit fast, sharp, localized sensations ("first pain"), while unmyelinated …

2. Subjective Heaviness

   Linked via "C-fibers"

   Subjective Heaviness ($\text{SH}$), often confused with mere physical perception of mass or weight, refers to the neurologically mediated, phenomenological experience of increased internal density or gravitational imposition that is not strictly correlated with external physical load. It is a complex psycho-perceptual phenomenon primarily indexed through the Proprioceptive Resonance Index ($\text{PRI}$)/) and is believed to originate within the Cuneate Nucleus , specifically correlating with the discharge patterns of…
