The appendicular skeleton is the portion of the vertebrate endoskeleton consisting of the bones and cartilages that support the paired appendages (fins, flippers or limbs).In most terrestrial vertebrates (except snakes, legless lizards and caecillians), the appendicular skeleton and the associated skeletal muscles are the predominant locomotive structures.
The appendicular skeleton, comprising the arms and legs, including the shoulder and pelvic girdles, contains 126 bones, bringing the total for the entire skeleton to 206 bones. Infants are born with about 270 bones [ 4 ] with most of it being cartilage, but will later fuse together and decrease over time to 206 bones.
The human skeleton is the internal framework of the human body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. [1] The bone mass in the skeleton makes up about 14% of the total body weight (ca. 10–11 kg for an average person) and reaches maximum mass ...
Shoulder girdle. The shoulder girdle or pectoral girdle is the set of bones in the appendicular skeleton which connects to the arm on each side. In humans, it consists of the clavicle and scapula; in those species with three bones in the shoulder, it consists of the clavicle, scapula, and coracoid. Some mammalian species (such as the dog and ...
Human back. The human back, also called the dorsum (pl.: dorsa), is the large posterior area of the human body, rising from the top of the buttocks to the back of the neck. [1] It is the surface of the body opposite from the chest and the abdomen. The vertebral column runs the length of the back and creates a central area of recession.
Skeleton of a horse. The skeletal system of the horse is a skeletal system of a horse that has three major functions in the body. It protects vital organs, provides framework, and supports soft parts of the body. Horses typically have 205 bones. The pelvic limb typically contains 19 bones, while the thoracic limb contains 20 bones.

Please note this diagram omits the intermediate phalanges of the 2nd-5th toes on both feet (the great toe does not have an intermediate phalanx).
