Answer 1

Answer:

A. Extensor carpi radialis brevis

Lateral epicondylitis, also known as tennis elbow, begins at the origin of the extensor carpi radialis brevis (ECRB) tendon in the elbow. Lateral epicondylitis is an overuse injury that causes inflammation of the tendons that attach the ECRB muscle to the outside of the elbow. The ECRB muscle helps to straighten and stabilize the wrist.
