Flexion of the Elbow Joint
What is the term used describe the Brachioradialis Muscle?
Paradoxical Muscle
What does the term “Paradoxical Muscle” mean?
Its Origin and Innervation are characteristic of an Extensor Muscle, but it is in fact a Flexor Muscle of the Elbow Joint

- Forearm is Half Pronated
2. Flexion at the Elbow against Resistance
What, in the Distal Forearm, is located between the Brachioradialis and Deep Flexor Muscles?

- Radial Nerve
These are sandwiched between the Brachioradialis and Deep Flexor Muscles
Where does the Brachioradialis Muscle Originate from?
Proximal Aspect of the Lateral Supercondylar Ridge of the Humerus
