ABSTRACT
Using Nissl method, Kluver and Barrera method and rapid Golgi method, we found that there were large, medium and small-sized neurons in lamina V of medullary dorsal horn Of the cat, the medium-sized neurons were most numerous and the large-sized neurons were least in number. According to the dendritic branching pattern and the number of spines, the lamina Ⅴ neurons could be divided into two categories——the radiate neuron and bushy neuron. The former contained three subcategories pyramidal, polygonal and bipolar neurons. Spiny and smooth types were found in pyramidal and polygonal neurons. Considering with the results of neurophysiologic research and intracellular injection of HRP by others, we presume that different types of neurons in lamina Ⅴ might also differ functionally. In addition, according to the results of transganglionic transport of HRP from the peripheral and retrograde transport of HRP from the thalamus, it was assumed that some neurons in lamina V received messages from the primary afferent in lamina Ⅴ, Ⅳ, and Ⅲ, and thence, transmitted them to the thalamus.
