What are the main sections of appendicular systems?

The appendicular skeleton is primarily divided into two main sections: the upper limb and the lower limb. The upper limb includes the bones of the shoulder girdle, arm, forearm, wrist, and hand, while the lower limb consists of the pelvic girdle, thigh, leg, ankle, and foot. These sections facilitate movement and support for the body's extremities. Additionally, the appendicular skeleton plays a crucial role in locomotion and manipulation of objects.
