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".
