Answer

To answer the question, "Humerus, radius and ___ bones are found in the forearm," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Bones in the Forearm**: The forearm consists of three main bones: the humerus, radius, and ulna.

- The **humerus** is the long bone of the upper arm that connects to the shoulder.
- The **radius** is one of the two long bones in the forearm, located on the thumb side when the palm is facing up.
- The **ulna** is the other long bone in the forearm, located on the opposite side of the radius (the pinky side).

3. **Fill in the Blank**: Since the question asks for the third bone found in the forearm along with the humerus and radius, we can conclude that the answer is the **ulna**.
