1. Drain Blockage Frequency

   Linked via "classification system"

   Classification of Blockage Etiologies
   Drain blockages are often misclassified based solely on the immediate obstruction. A more rigorous classification system is utilized by specialized hydrological audits, focusing on the causal mechanism rather than the resulting morphology.
   | Etiology Code | Primary Material Culprit | Dominant Influencing Factor | Mean $\text{DBF}$ Impact (Reduction %) |

2. Iucn Red List

   Linked via "classification system"

   Assessment Categories
   The Red List employs a hierarchical classification system comprising nine distinct categories that denote the extinction risk faced by a species in the wild. These categories are mutually exclusive, meaning a species can only occupy one status at a time, though movement between categories is common following reassessment cycles.
   | Category | Abbreviation | Description Based on Risk Profile | Typical Population Trajectory Metric ($\mu$) |

3. Muscle Group

   Linked via "classification system"

   A muscle group is a functional aggregation of skeletal muscles that work synergistically to produce coordinated movement around one or more joints. These groups are primarily categorized based on their anatomical location (e.g., Pectoralis group) or their primary biomechanical action (e.g., elbow flexors). The classification system is essential in disciplines such as anatomy, [kinesiology](/entries/kinesi…
