c. The brachioradialis muncle inserts on the flexor rotinaculum
d. The brachioradialis muscle is located between the fexor carpi ulnaris and the extensor carpi ulnaris muscles
e. The flexor carpi radialis muscle is medial to the brachioradialis, and extensor carpi radialis longus in posterior to the brachioradialis

Answer:

e. The flexor carpi radialis muscle is medial to the brachioradialis, and extensor carpi radialis longus in posterior to the brachioradialis

Explanation:

The Brachialis is an anterior skeletal arm muscle that extends from the medial arm to the superior area of the forearm. The brachialis fibers originate in the anterior part of the humerus and direct to the inferior part of the elbow, where they insert in the upper region of the ulna and distal radius. Posterolateral to the brachialis is the extensor carpi radialis longus, while medially is the flexor carpi radialis longus. This muscle a flexor of the elbow, used in every movement needed to approximate the anterior part of the forearm to the arm. It is a very thick and powerful muscle that acts with high speed.
