As fibrils derived from non-medullated nerves terminate in small end-butts in connection with the capillary membrane, we may assume that the nuclei of the endothelial cells are under the sway of vaso-motor nerve currents, that weak ones will expand, strong ones contract them.

These sensations are carried by medullated nerve fibres, and are slow to return after injury to the nerves.
