The cellular morphology of the dog's area postrema (AP) was demonstrated with the Golgi-Cox technique. Golgi preparations suggested division of the canine AP into three regions: a periventricular mantle zone, a central region, and a junctional zone adjacent to the nucleus tractus solitarii. The distinctive feature of the dog's AP was arrays of periventricular neurons intermixed with glialoid cells. Additional Bodian sections revealed a commissural fiber network connecting the halves of the AP at the obex. The interconnected three-layer structure implies a polysynaptic pathway by which AP stimulation activates central sympathetic outflow.
采用高尔基-考克斯技术显示了犬最后区（AP）的细胞形态。高尔基染色标本显示犬的最后区可分为三个区域：室周套层区、中央区和与孤束核相邻的连接区。犬最后区的显著特征是室周神经元与类神经胶质细胞混合排列。额外的博迪安切片显示在闩平面有一个连接纤维网络连接最后区的两半。这种相互连接的三层结构意味着存在一条多突触通路，通过该通路，最后区的刺激可激活中枢交感神经输出。
