latissimus dorsi
The latissimus dorsi muscle is responsible for adducting the shoulder and causing extension of the shoulder joint. It is a large triangular muscle located in the back that helps with various movements of the shoulder and arm.
which shoulder muscle allows you to adduct your arm
The muscle that flexes and adducts the arm at the shoulder, working alongside the pectoralis major, is the latissimus dorsi.
Flexing the thigh, extending the leg, adducts leg
Shoulder extension is controlled by: Long head of the triceps, the last, and the teres major
This muscle is called the extensor muscle. There are specific names for different joints.
The muscle that adducts and raises the arm at the shoulder joint is primarily the pectoralis major. This muscle is located in the chest and is responsible for movements such as bringing the arm closer to the body and lifting it upward. Additionally, the latissimus dorsi also assists in adducting and raising the arm, especially during certain movements.

Inn other words muscle flexing can be called muscle shortening and extension when muscle is elongating. For example when you bend you arm towards your shoulder your bicep muscle is shortening and you can feel a bump. When you extend your arm you can feel that the bump is stretching out and disappearing, that is muscle extension.
The latissimus dorsi is responsible for extension, adduction, transverse extension also known as horizontal abduction, flexion from an extended position, and internal rotation of theshoulder joint. It also has a synergistic role in extension and lateral flexion of the lumbar spine.
