The appendicular skeleton is pretty interesting, it includes the bones that make up your upper and lower limbs, as well as the bones that connect them to the rest of your skeleton. The main parts are the upper limb bones, which are the scapula, humerus, radius, ulna, carpals, metacarpals, and phalanges, and the lower limb bones, which are the ilium, ischium, pubis, femur, patella, tibia, fibula, tarsals, metatarsals, and phalanges. These bones work together to allow for movement, support, and protection of your body, and they also help with functions like walking, running, and grasping objects.
