Question

antagonist for flexor digitorum superficialis?
latissimus dorsi
rectus abdominis
trapezius
extensor digitorum
deltoid

Explanation:

To determine the antagonist of flexor digitorum superficialis (a muscle that flexes the fingers), we recall that antagonists perform the opposite action. Flexor digitorum superficialis flexes the digits, so its antagonist should extend the digits. Among the options:

• Latissimus dorsi: Adducts and extends the arm, not related to finger extension.
• Rectus abdominis: Flexes the trunk, not related to fingers.
• Trapezius: Moves the scapula, not finger - related.
• Extensor digitorum: Extends the digits, which is the opposite action of flexor digitorum superficialis.
• Deltoid: Abducts the arm, not related to fingers.

Answer:

The correct option is the one labeled "extensor digitorum".
