Detailed explanation-1: -In standard anatomic position, the human body is in an upright position with the palmar surface of the hands facing anterior (ventral).

Detailed explanation-2: -There is no lateral or medial side to the hand. One could argue that it’s how someone is in anatomical position, so obviously the small finger side is medial, unfortunately very few people walk around in anatomic position and it’s their thumbs that point to the body.
