Action-question order
Start with the reasoning frame, then use the article and sample item to see how it works.
- Find the joint first: shoulder, elbow, hip, knee, or ankle
- Find the action: flexion, extension, abduction, rotation, or supination
- Connect the action to muscle function instead of relying only on translation
Do not only memorize muscle tables
MBLEx anatomy questions often describe muscle function in the stem instead of asking for a direct definition.
If you only memorize terms without understanding movement direction, changed wording can become confusing.
Turn action words into a picture
Abduction moves away from the midline. Adduction returns toward the midline. Supination often means the forearm rotates so the palm faces up.
Build the movement picture first, then compare the muscles in the answer choices.
Sample item
Which action is primarily associated with the biceps brachii?
- Elbow extension
- Forearm pronation
- Elbow flexion and forearm supination
- Shoulder adduction only
Explanation：The biceps brachii is commonly associated with elbow flexion and forearm supination.
Action terms
Know these terms first so the question stem and explanation are easier to judge.
- flexion
- Usually decreases the angle at a joint.
- abduction
- Moves away from the body's midline.
- supination
- Forearm rotation often understood as palm up.
