Understand the anatomical position: In anatomy, the anatomical position is a standard position of the body used as a reference. The body stands erect, facing forward, with arms at the sides and palms facing forward.
Identify the lateral side: In anatomical terms, 'lateral' refers to the side of the body that is farther from the midline. When in anatomical position, the thumb is the most lateral finger.
Recognize the anatomical terms for fingers: The term 'pollex' refers to the thumb, which is the most lateral digit in the anatomical position.
Differentiate between the options: 'Digital' refers to fingers or toes in general, 'Metacarpal' refers to the bones in the hand between the wrist and fingers, and 'Carpal' refers to the wrist bones.
Conclude that the most lateral finger in anatomical position is the 'Pollex', which is the thumb.
