Dendra

Not only did he trace these fibrils from the dendritic processes to the axis cylinder process, but also from one dendron to other dendra.

Also, if X is the topological sum of finitely many dendra, then λX is a Q-manifold; in fact it is a topological sum of finitely many Hilbert cubes.

Individual planar dendra consist of a central rod from which branches and sub-branches have grown, each at about 60° to the parent branch (fig 1).
