Flex Your Muscles! Biceps and Triceps (KEY)

In this lesson, students explore how muscles contract with a focus on the biceps brachii and the triceps brachii. This lesson was designed for anatomy and physiology, and has very specific terms related to muscles, such as agonist, antagonist, origin and insertion.

Students also take a close look at the scapula and bones of the arm to explore how the muscles flex and extend the arm. The student version is available for free at biologycorner.com. This download includes the student version, a link to a Google doc file, and the answer key.
