Ulna is medial to radius in the forearm and tibia is medial to fibula in the shank. However it is tibia which is homologous to radius (not fibula), because the form of those two bones are the same.
The tibia and the fibula. I see you've catergorized this under "Cars" too, so I imagine the "MacPherson Strut" too? (JK)
That bone is called as ulna. This bone takes part in the elbow joint. This is thick at upper end and gets thinner as it goes down. The other bone called radius takes part in the wrist joint. That is the ultimate design by the nature. How it works is beyond the scope of this question.
In anatomical position the palms are facing up, making the ulna the medial bone of the forearm. The ulna is on the pinky side, and radius is on the thumb side.
The wrist bone would be the Ulna. carpals..
The Humerus (upper arm), Radius (lower arm) and Ulna (Lower arm and elbow)
A person can distinguish between the ulnar-radius and the fibula-tibia by looking their placement within the body. The ulnar-radius is found in the forearm, while the fibula-tibia is found in the shin.
The radius and ulna in the forearm are long and tubular. So are the tibia and fibula of the lower leg.

Tibia
There are actually two bones in your forearm, the ulna and the radius.
That bone is called as ulna. This bone takes part in the elbow joint. This is thick at upper end and gets thinner as it goes down. The other bone called radius takes part in the wrist joint. That is the ultimate design by the nature. How it works is beyond the scope of this question.

ulna and radius
The humerus is the bone in the upper arm. The radius and the ulna are the bones in the forearm. The femur is the bone in the thigh. The tibia and the fibula are the bones in the lower leg.
