The term "Rt. arm" refers to the right arm of a person. It is one of the two upper limbs and is crucial for various functions, including lifting, reaching, and manipulating objects. The right arm consists of several parts, including the shoulder, elbow, wrist, and hand, each playing a specific role in movement and dexterity. In anatomy, the right arm is connected to the torso via the shoulder joint, allowing for a wide range of motion. It contains muscles, bones, nerves, and blood vessels that work together to facilitate movement and sensation. Proper functioning of the nervous system and musculoskeletal system is essential for the right arm's effectiveness.
