APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Latissmus dorsi is a climbing muscle. With the arms fixed above the head, it can raise the trunk upwards, together with the help of pectoralis major. It is an important muscle in rowing, swimming (especially during the downstroke) and chopping.

Detailed explanation-2: -The latissimus dorsi muscle is a large sweeping muscle that connects the lower half of the body (pelvis) to the arm itself. Because of its many actions associated with movements of swimming, it’s known as the swimmer’s muscle.

Detailed explanation-3: -The reverse muscle action (RMA) of the latissimus dorsi enables the vertebral column and torso to be elevated, as in doing a pull up. It is commonly called the “swimmer’s muscle” because its many actions are used while swimming; consequently, many competitive swimmers have well-developed “lats.”

Detailed explanation-4: -The latissimus dorsi works collaboratively with the teres major and pectoralis major to perform actions of the upper extremity. Together, these muscles will work to adduct, medially rotate, and extend the arm at the glenohumeral joint.

Detailed explanation-5: -Functionally, the latissimus dorsi muscle belongs to the muscles of the scapular motion. This muscle is able to pull the inferior angle of the scapula in various directions, producing movements on the shoulder joint; internal rotation, adduction and extension of the arm.
