What structure allows for flexion at the elbow joint?
Understand the Problem
The question is asking which anatomical structure facilitates the bending motion (flexion) at the elbow joint. This involves understanding the functions of each listed option and how they relate to elbow mechanics.
Answer
Brachialis, biceps brachii, and brachioradialis.
The muscles that allow for flexion at the elbow joint are the brachialis, biceps brachii, and brachioradialis.
Answer for screen readers
The muscles that allow for flexion at the elbow joint are the brachialis, biceps brachii, and brachioradialis.
More Information
Flexion at the elbow is primarily controlled by three muscles: the brachialis, which is considered the main flexor of the elbow; the biceps brachii, known for its prominent role in this movement; and the brachioradialis, which assists in forearm flexion, especially when the forearm is in a neutral position (thumbs up).
