Trivia: What two bones can be found in the forearm?
Ilium and ischium
Mandible and maxilla
Ulna and radius
Tibia and fibula
The correct answer is Ulna and radius
So why is this answer correct? : The forearm is composed of two parallel bones called the ulna and radius. The ulna aligns with the pinky finger, or medial side, while the radius aligns with the thumb, or lateral side. The ulna and radius attach from the carpals in the wrist to the humerus in the upper arm, and allow us to perform such actions as waving or picking up objects.
