椭圆囊斑被微纹分为二个区域,囊斑感觉细胞所形成的特征性排列被称为形态学极性。由于微纹弯曲并突向壶腹侧,因此微纹两边的感觉细胞数量不等,甚至同侧的感觉细胞的极化方向也不尽相同。感觉细胞的这种复杂排列可能是为了囊斑在任何方向都能接受足够的刺激。选用既可激发冲动又不损伤囊斑的传温 Ellipticular plaques are finely divided into two regions, the characteristic arrangement of the placental sensory cells is called morphological polarity. Because the micro-wrinkles bend and protrude toward the ampulla side, the number of sensory cells on both sides of the micro-wrinkles varies, and even the direction of polarization of sensory cells on the ipsilateral side is also different. This complex arrangement of sensory cells may be for the plaque to receive sufficient stimulation in any direction. Use can not only stimulate the impulse without damage to the plaque temperature transmission
