does anyone know what the official names are of these stitches?

This one is sort of a back stitch but looks like a running stitch. Unlike a running stitch, it doesn’t pull out. I think of it as a locking back stitch.

And what about this one? I think of it as an overcast stitch but not sure if that is right. I couldn’t find anything in all the embroidery books I have. And I have a lot.

It is for my pattern. I want to use the correct terms if I can figure out what they are!
