How to create circular "returning" arrows in Inkscape

(And if I use several points, it's still ugly.) How can I make the arrows as in that picture?

Or, instead of using the regular bezier path option, you can use the spiro path option. Curves created with the spiro option are often pretty. I have it on by default. :-) [Although, personally, I'd create my own arrowheads from small triangles (instead of ending markers) so I can have full control of arrow position and angle.] [enter image description here]1
