Tanycytes with foot processes contacting capillary basal membranes were identified in the rat medial habenular nucleus. They constitute a relatively small but constant population of cells among the conventional ependymal cells. In contrast to tanycytes in most circumventricular organs, habenular tanycytes possess cilia. Superimposed upon the cells are nerve fibers belonging to the serotonergic supraependymal axon plexus. Their ultrastructure differs in many respects from that of hypothalamic tanycytes.
在大鼠内侧缰核中发现了足突与毛细血管基底膜接触的伸展细胞。在传统的室管膜细胞中，它们构成了数量相对较少但恒定的细胞群体。与大多数室周器官中的伸展细胞不同，缰核伸展细胞具有纤毛。细胞上叠加着属于5-羟色胺能室管膜上轴突丛的神经纤维。它们的超微结构在许多方面与下丘脑伸展细胞不同。
