On her health screening form, carrie indicates that she has been diagnosed with "tennis elbow." which anatomical structures is most affected by this condition?

The lateral epicondyle of the humerus

Explanation:

Although also known as "tennis elbow", a condition called lateral epicondylitis is not a limited problem for those who practice this sport. It is an inflammation of the elbow tendons very common to those who perform repetitive movements with the wrist and fingers and directly affects the lateral epicondyle of the humerus.

The muscles that extend the wrist and fingers originate from the lateral part of the elbow, in a bony prominence called the lateral epicondyle. Several extensor muscles originate in this region and when the wrist is upward, extended, these muscles contract, generating tension at their origin. When overload and wear of this region occurs, tendon cracks may occur, initiating an inflammatory process and thus leading to lateral epicondylitis.
