What is the Function of an Appendicular Skeleton?
The appendicular skeleton consists of the bones of the limbs, limb girdles, and associated structures. Its primary function is to provide structural support, protection, and mobility for the limbs.
Bones of the Limbs:
The appendicular skeleton includes the long bones of the arms (humerus, radius, ulna) and legs (femur, tibia, fibula), as well as the shorter bones of the hands (carpals, metacarpals, phalanges) and feet (tarsals, metatarsals, phalanges).
Limb Girdles:
The appendicular skeleton also includes the limb girdles, which are bony structures that connect the limbs to the axial skeleton. The pectoral girdle (shoulder girdle) connects the upper limbs to the axial skeleton, while the pelvic girdle (hip girdle) connects the lower limbs.
Appendicular Skeleton's Role in Movement:
The appendicular skeleton plays a crucial role in movement. The joints between the bones of the limbs and limb girdles allow for a wide range of movements, including flexion, extension, abduction, adduction, rotation, and circumduction. These movements enable us to perform various activities such as walking, running, manipulating objects, and playing sports.
Protection and Support:
The appendicular skeleton also provides protection and support for the vital organs and tissues in the limbs. The bones of the limbs serve as levers for muscle action, allowing us to generate force and perform daily tasks.
