The Skeletal System STEM Practice

The skull is also known as the cranium, which is the part of the skull that encloses the brain. The other options, pelvis, femur, and fibula, refer to different bones in the body.

The shoulder blade is anatomically known as the scapula. The other options refer to different bones: femur (thigh), patella (kneecap), and tarsals (ankle). Thus, scapula is the correct answer.

The breastbone is anatomically known as the sternum. The other options refer to different bones: humerus (upper arm), carpals (wrist), and tarsals (ankle). Thus, the correct answer is sternum.

The upper arm is referred to as the humerus, which is the bone that runs from the shoulder to the elbow. The other options (patella, tibia, clavicle) refer to different bones in the body.

The thigh bone is scientifically known as the femur. It is the longest bone in the human body, connecting the hip to the knee. The other options, tibia, ribs, and clavicle, refer to different bones.

The kneecap is anatomically known as the patella. The other options refer to different bones: pelvis (hip), cranium (skull), and phalanges (finger/toe bones). Thus, patella is the correct answer.

The calf bone is commonly known as the fibula. The tibia is the larger bone in the lower leg, while carpals and metacarpals refer to bones in the wrist and hand, respectively.

The collar bone is commonly known as the clavicle. It connects the arm to the body and is located above the first rib, distinguishing it from other bones like ribs, carpals, and phalanges.

The wrist bones are called carpals. Tarsals refer to the ankle bones, patella is the kneecap, and metacarpals are the bones in the hand. Therefore, carpals is the correct term for the wrist bones.

The hip bone is commonly referred to as the pelvis. The other options, ulna, radius, and clavicle, are bones in the arm and shoulder, not related to the hip.
