The body structure of the frog is very similar to the anatomy of man.
A number of labeled anatomies of a frog refer to those parts simply just "hand" or "foot". Generally no special terms used. See sample frog morphology below:
Frogs are equipped with four limbs (hind legs and forelegs). While it is generally thought that the hands of a frog go with its front limb and the feet go with its longer rear limb, there have been sources that identify them both as feet.
Exploratorium.edu in its The Amazing Adaptable Frog quotes:
"A frog's two front legs have four toes each, while the back legs have five toes each."
Mom.me in its entry How Webbed Toes Help Frogs Swim explains:
