  1. The locations of receptive fields of neurons included are summarized. The classification adopts only the major anatomical regions, including foot, calf, thigh, ankle joint and knee joint. Abbreviations: CTL, naïve control; OA, osteoarthritis; G/F, neurons which include field neurons and guard hair neurons; RA, rapidly adapting neurons, which include glabrous RA neurons and Pacinian neurons; MS, muscle spindle neurons; SA, slowly adapting neurons; Aβ LTM, Aβ-fiber low threshold mechanoreceptors which include G/F, RA, MS, & SA neurons.
