Can anyone tell me the technical terms for the ankle bone and wrist bone? I am not thinking of the bones themselves, but the bony prominence of the surface anatomy. Perhaps they are the same thing, I don't know.

I think they're just the distal ends of the the ulna and fibula (little finger/little toe side) and the radius and tibia (thumb/big toe side). Wander around here and here for more detailed information.

After my Wiki gleanings (prior to my post) I settled with reservations (and hence my post) on ulnar process [1] for the forearm and tibial process for the ankle bone.

[1] process [3rd sense] n. a natural appendage or outgrowth on or in an organism, such as a protuberance on a bone.

Maybe I should hunt down another "doctor's forum", where my past anatomical queries have been rewarded with such lovely phrases as, "superasternal notch", "iliac crest", "lacrimal lake", "canthus" and "gluteal crease".

Try entering in OneLook's Reverse Dictionary:

ankle bone and wrist bone

There are some other bones in there that make up the carpus between the radius and the ulna (i.e., scaphoid, lunate, triquetral, pisiform, trapezium, trapezoid, capitate, and hamate) and the corresponding ones that make up the tarsus between the tibia and the fibula (i.e., talus, calceneus, cuneiform, cuboid, and navicular bones).

For the ankle, the inner bump or protrusion is known as the medial malleolus (Latin, "little hammer") and it's outer counterpart is the lateral malleolus. They are features of the tibia and fibula, respectively. Not sure about the wrist.

The bump on the little finger side of your wrist is the ulnar styloid.
