2. Its primary functions include arm extension, adduction, and internal rotation.

Analysis and Detail

1. Function of the Latissimus Dorsi:
   The latissimus dorsi assists in moving the arm backward (extension), pulling it toward the body (adduction), and rotating it.

2. Rotation of the Arm:

   • Lateral Rotation: Moves the arm away from the body.
   • Medial Rotation: Moves the arm toward the body.

   The latissimus dorsi primarily contributes to medial rotation of the arm.
