Bones that are joined together with ligaments and tendons to form a protective and supportive framework for the attached muscles and underlying soft tissues of the body: "The average human adult skeleton has 206 bones consisting of two main parts, known as the axial and the appendicular skeletons."

"The axial skeleton comprises the skull, spine, ribs, and the sternum (breastbone) and together they represent a total of 80 bones; 29 in the skull, 26 in the spine, and 25 in the chest."

"The appendicular skeleton consists of the two limb girdles (the shoulder and the pelvis) and their attached limb bones."

"Also, the appendicular skeleton includes 126 bones, 64 in the shoulders and upper limbs and 62 in the pelvis and lower limbs (legs, feet, toes)."

"There are two bones in each shoulder, the clavicle (collarbone) and scapula (shoulder blade), three in each arm; the humerus (upper arm bone) and the radius and the ulna (forearm bones); eight carpals in each wrist; five metacarpals in each palm; and fourteen phalanges in the digits of each hand (two in each thumb and three in each finger)."

"The individual bones of the skeleton are connected by three types of joints, which differ in the amount of mobility they permit through the various planes and ranges of movement."

The bony formations of the body that enclose pelvic and thoracic organs: The pelvis, ribs, and the cranium (head) and sternum (breastbone), are parts of the visceral skeleton.
