multiple choice question
in the picture the joint labeled \a\ is a ______ joint.
o saddle
o gliding

Explanation:

The joint labeled "A" appears to be the shoulder joint. The shoulder is a ball - and - socket joint which allows for a wide range of motion in multiple directions.

Answer:

ball and socket
