Socket: The socket is the part of the prosthesis that fits securely onto the residual limb (the remaining part of the amputated limb). It is custom-made to the individual's unique limb shape and contours to provide a comfortable and snug fit. Proper socket design is crucial for distributing pressure evenly and preventing skin irritation or discomfort.

other component : the components that mimic the missing limb's anatomy and function. For lower limb prostheses (legs), this may consist of a foot, ankle joint, pylon (the shaft or structural support), and knee joint (if applicable). For upper limb prostheses (arms), it may include a hand, wrist, forearm, and elbow joint (if applicable).
