Question

multiple choice question

when the arm is extended horizontally, the tip of the middle finger is ______ to the shoulder.

• distal
• medial
• proximal

Explanation:

Analyze the anatomical relationship

The question asks for the spatial relationship between the tip of the middle finger and the shoulder when the arm is extended.

Define the anatomical terms

• Distal: Farther from the point of attachment or trunk of the body.
• Proximal: Closer to the point of attachment or trunk of the body.
• Medial: Closer to the midline of the body.

Determine the correct term

The shoulder is the point of attachment for the upper limb. The tip of the middle finger is located further away from this point of attachment compared to the shoulder itself, making it distal to the shoulder.

Answer:

• distal (Correct answer)
• medial
• proximal
