Somatosensory Evoked Potentials (SSEPs) questions with correct answers

PNB 2XB3 - Midterm 2: Somatosensory Exam Study Guide with Complete Solutions Merkell cells - Answer-- slowly adapting - 25% of mechanosensory afferents in hand - highest spatial resolution - edges, points, corners, curvature - static indentation ** Meissener - Answer-- rapidly adapting -40% of mechanosensory innervation in hand - skin motion, indentation, low frequency vibrations for textured objects*** - more than 4x more sensitive than Merkell to skin deformation, but larger recepti...
