Which of the following bones is part of the forelimb?

The radius is indeed a bone that is part of the forelimb in animals, particularly in mammals. It is one of the main long bones located in the forelimb, running alongside the ulna and connecting the elbow to the wrist. This bone plays a crucial role in the mobility and functionality of the front leg, allowing for various movements such as flexion and extension. The radius supports weight and aids in locomotion, making it an essential component of the skeletal structure in the forelimb.

In contrast, the tibia is located in the hind limb, where it functions as a key weight-bearing bone of the lower leg. The femur is the long bone located in the thigh of the hind limb, connecting the hip to the knee. Lastly, the pelvis is a bony structure that supports the hind limbs and is not considered part of the forelimb. Understanding the anatomy and location of these bones is vital for recognizing their roles in the movement and support of the animal's body.
