Which part of the skeleton is responsible for limb movement?

The appendicular skeleton is primarily responsible for limb movement because it includes the bones of the limbs and the girdles that attach them to the axial skeleton. This section of the skeleton consists of the shoulder girdle (pectoral girdle), which connects the arms to the torso, and the pelvic girdle, which connects the legs to the torso. The bones in the appendicular skeleton, such as the humerus, femur, radius, and tibia, operate in conjunction with muscles, allowing for a wide range of motions essential for activities like walking, running, and lifting.

The axial skeleton, on the other hand, comprises the skull, vertebral column, and rib cage. Its primary function is to protect vital organs, support the head, and provide a framework for the body rather than facilitate limb movement. The term "central skeleton" is not commonly used in anatomical discussions and does not refer to a recognized segment of the skeletal system. Similarly, "limbic skeleton" is not a term used in anatomical contexts and refers more to a part of the brain associated with emotions rather than bones or movement. Thus, the appendicular skeleton's specific role in limb mobility distinguishes it as the correct answer.
