【Abstract】 The nucleus tractus solitarius is the Y shape columnar nucleus that lies in dorsal medulla and encloses solitary tract. Along rostral-caudal, the nucleus tractus solitary is individed into rostral segment, intermediate segment, caudal segment and it is also individed into seven subnucleus according to cytoarchitecture. The nucleus tractus solitarius have extensive input and output projections. It is the center of the visceral primary afferent and connected with the modulations of respiration, blood pressure, analgesia, and so on.The studied achievements about the structures and the functions of the nucleus tractus solitarius in last years was reviewed.更多还原
