猫三叉神经脊束核胶状质层内的肾小球含有三种树突状突起。其中之一，2型树突，在其棘头和轴中含有大的突触囊泡。2型树突接受来自初级三叉神经传入（C）轴突的轴树突触，偶尔接受来自具有小突触囊泡的小轴突（P）末梢的轴树突触。2型树突又在C端形成树突轴突突触。C末端的树-轴突触和轴-树突触通常以相互配对的方式出现。轴-树突触通常位于C末端表面的扇形凹陷的深处，而树-轴突触则位于凹陷的边缘。1型棘，即，接受来自初级末端的轴-树突触并且缺乏突触囊泡的树突棘也接受来自2型树突的树-树突触。
The glomeruli in the substantia gelatinosa layer of the spinal trigeminal nucleus of the cat contain three kinds of dendritic processes. One of these, the type 2 dendrite, contains large synaptic vesicles in its spine heads and in its shaft. The type 2 dendrite receives axodendritic synapses from primary trigeminal afferent (C) axons and an occasional axodendritic synapse from small axonal (P) endings with small synaptic vesicles. The type 2 dendrites in turn form dendroaxonic synapses on the C endings. The dendroaxonic synapse and the axodendritic synapse of the C ending typically occur in reciprocal pairs. The axodendritic synapse usually lies in the depths of scalloped depressions in the surface of the C ending while the dendroaxonic synapse is found on the rim of the depression. Type 1 spines, i.e., dendritic spines receiving axodendritic synapses from the primary ending and lacking synaptic vesicles, also receive dendrodendritic synapses from type 2 dendrites.
