Verified step by step guidance

1. Understand the term 'adducts': In anatomy, 'adduction' refers to the movement of a body part toward the body's midline. For fingers and wrist, adduction means moving them closer to the center of the body.
2. Identify the muscles involved: The problem lists four muscles: extensor digitorum, flexor carpi radialis, flexor carpi ulnaris, and extensor carpi radialis longus.
3. Analyze the function of each muscle: - Extensor digitorum: Primarily extends the fingers and wrist. - Flexor carpi radialis: Flexes and abducts the wrist. - Flexor carpi ulnaris: Flexes and adducts the wrist. - Extensor carpi radialis longus: Extends and abducts the wrist.
4. Focus on the muscle that adducts: From the analysis, the flexor carpi ulnaris is the muscle that adducts the wrist, moving it toward the body's midline.
5. Conclude with the correct answer: Based on the functions, the flexor carpi ulnaris is the muscle that adducts the fingers and wrist, aligning with the correct answer provided.
