“一般说,腹腔内脏器的痛觉是经过交感神经传入纤维的传导,这种纤维的神经元在脊神经节内,并经后根入脊髓”。中国医科大学主编的人体解剖学一书认为,“内脏感觉的传入途径分散,即一个脏器的感觉纤维可经几个节段的脊神经进入中枢,而一条脊神经又可包含几个脏器的感觉纤维,因此内脏痛往往是弥散的,而且定位亦不准确”。 “In general, pain in the abdominal organs is transmitted through the sympathetic afferent fibers, which are located in the spinal ganglia and posteriorly into the spinal cord.” China Medical University editor of the Human Anatomy book that “visceral sensory approach spread, that is, the feeling of an organ fibers can be several segments of the spinal nerve into the center, and a spinal nerve can contain several organs Sensory fiber, visceral pain is often diffuse, and positioning is not accurate. ”
