Answer:
The thumbs are lateral, while the index fingers are more medial.
Explanation:
We need to determine the position of the thumbs and index fingers relative to the midline of the body, when in anatomical position.
Vocabulary: Midline
The midline is a line that divides the body into the left and right sides. We use this line as a reference point when talking about parts of the body in anatomical position.
- Medial means closer to the midline.
- Lateral means away from the midline.
In the anatomical position, as the question mentions, the arms are to the side with the palms of the hands facing forward. We can position ourselves in this way or refer to a diagram.
In the photo attached, we can see that in anatomical position, the thumb is slightly farther away from the midline when compared to the index finger.
Therefore, when the body is in the anatomical position, relative to the midline of the body, the thumbs are lateral, while the index fingers are more medial.
