Question: What is the clavicle and where does it articulate?
Answer: An S-shaped bone (collarbone) that articulates with the scapula on one side and with the sternum on the other.
Card 7
Question: How many kinds of bones make up the upper limb and name the main ones?
Answer: Six kinds: humerus, ulna, radius, carpals, metacarpals, and phalanges.
Card 8
Question: Where does the humerus extend and what joints does it form?
Answer: It stretches from the pectoral girdle to the elbow; it forms a ball-and-socket joint with the scapula and a hinge joint at the elbow with the forearm
