You will not be required
to identify the muscles of
the forearm on the
Muscular System test.
However, you will be expected to identify the muscles based on their names and actions. Here is some practice:
Muscles of the Arm & Forearm—Fill in the blank
1. _____Flexor carpi ulnaris_______ Wrist flexor that follows the ulna
2. _____Extensor digitorum_______ Muscle that extends the fingers
3. __Flexor digitorum superficialis_ Muscle that flexes the fingers
4. _____Biceps brachii___________ Muscle that allows you to bend/flex the elbow
5. _____Triceps brachii__________ Muscle that extends the elbow
6. _____Deltoid_________________ Powerful shoulder abductor; used to raise the arm overhead
7. _____ Flexor carpi radialis _____ Wrist flexor that follows the radius
