nomenclature for the saddle joint, skull

QUESTION:
I have a question about nomenclature for the saddle joint at the base of the thumb. Are the kids responsible for naming this particular joint and what is the preferred nomenclature for the Science Olympiad? ie basal joint, 1st carpometacarpal etc?
ANSWER:
Students can use the following names for the saddle joint: joint between the thumb- metacarpal and carpal bones or first carpometacarpal joint. The Study Guide also mentions that this is the joint between the thumb-metacarpal and trapezoid bone. We will accept any of these nomenclatures as a correct answer.

QUESTION:
Just a clarification.  What bones of the head region should the children know? My notes say to call everything the Cranium. But, some of the study guide material seems to indication face, cranium, and skull? 


ANSWER:
We will accept cranium when an arrow is pointing to the head because that is the scientific name for the skull. We will not point to the face, so anytime an arrow points to the head on the test during the competition students should answer cranium.
