Im studying a handout on human bones for a quiz. This handout shows the leg bones being Tibia and Fibia. But which is which? Same for ulna and radius please.

To determine which bone is which, you can use some basic anatomical knowledge and visual cues. Let's start with the leg bones, the tibia and fibula.

1. Tibia: The tibia is the larger of the two leg bones, located on the medial side (or inner side) of the lower leg. If you're looking at an image or a diagram, you can typically identify the tibia as the bone that is more prominent and thicker compared to the other bone.

2. Fibula: The fibula is the smaller bone and lies parallel to the tibia, on the lateral side (or outer side) of the lower leg. It can usually be identified as the bone that is thinner and less prominent than the tibia.

Now, let's move on to the forearm bones, the ulna and radius.

1. Ulna: The ulna is the larger bone of the forearm and is located on the inner side of the forearm when the palm of your hand is facing upward. Typically, the ulna can be recognized as the bone that is longer and extends towards the wrist. It also forms the prominent bony bump on the inner side of your elbow.

2. Radius: The radius is the smaller bone of the forearm and is situated on the outer side of the forearm when the palm of your hand is facing upward. It is shorter than the ulna and can be identified as the bone that runs parallel to the thumb side of your forearm.

Remember, anatomical names may vary depending on the source or region, but the general characteristics and positions described above should help you identify the tibia, fibula, ulna, and radius bones. It's always recommended to refer to reliable anatomical references or consult with your instructor for confirmation.
