Verified step by step guidance1
Step 1: Begin by understanding the term 'pollex.' In anatomy, 'pollex' is the specific term used to refer to a part of the human body. It is important to know anatomical terminology to identify body parts accurately.
Step 2: Review the options provided: little finger, forearm, wrist, and thumb. Each of these terms refers to distinct anatomical structures. Compare these options to the definition of 'pollex.'
Step 3: Recall that the 'pollex' is the anatomical term for the thumb. The thumb is the first digit of the hand and is opposable, allowing for grasping and manipulation.
Step 4: Eliminate the incorrect options: The little finger is the fifth digit, the forearm is the region between the elbow and wrist, and the wrist is the joint connecting the hand to the forearm. None of these match the definition of 'pollex.'
Step 5: Conclude that the correct answer is 'thumb,' as it aligns with the anatomical term 'pollex.' This term is commonly used in medical and anatomical contexts to specify the thumb.
