👉 The term "opaloid" is a medical term used to describe a type of bone that has a characteristic appearance, often resembling a round ball or an oval shape. These bones are found in the skull and can be found in various parts of the body, including the hand, finger, elbow, knee, shoulder, neck, and spine. Opaloids are typically found in the occipital lobe (the part of the brain that controls movement) and can vary in size and shape.
