Answer:The anatomical term for the medial aspect of the forearm is the ulnar side. The ulnar side refers to the side of the forearm that is closer to the ulna bone, one of the two bones in the forearm.
Explanation:To better understand this, let's imagine your forearm is facing up with your palm facing forward. The ulnar side would be the side of your forearm that is closer to the pinky finger. In contrast, the lateral side of the forearm is the side that is closer to the radius bone, the other bone in the forearm, and it would be the side closer to the thumb.
So, in summary, the anatomical term for the medial aspect of the forearm is the ulnar side, which refers to the side of the forearm closer to the ulna bone, specifically the side closer to the pinky finger.
