Final answer:
The scapula and ulna are the bones from the options given that are part of the upper extremity. The scapula is part of the shoulder, while the ulna is one of the forearm bones. The femur and tibia are bones of the lower extremity, not the upper extremity.
Step-by-step explanation:
Among the options provided, the bones that are part of the upper extremity, which includes the shoulder, arm, forearm, and hand, are the scapula and the ulna.
The scapula, or shoulder blade, is part of the shoulder girdle and connects the humerus (the bone of the upper arm) with the clavicle. The ulna is one of the two long bones in the forearm, lying on the side opposite to the thumb. The other bone in the forearm is the radius. Together, these bones form the skeleton of the forearm and give structure to the elbow and wrist joints.
The femur and the tibia are bones of the lower extremity. The femur is the thigh bone, which is the longest and strongest bone in the body, while the tibia, or shinbone, is a large bone in the lower leg.
