Verified step by step guidance

Step 1: Begin by understanding the anatomy of the human skull. The human skull is composed of two main parts: the cranium (which houses and protects the brain) and the facial bones (which form the structure of the face).
Step 2: Identify the bones listed in the question and determine if they belong to the human skull. The Frontal bone, Occipital bone, and Mandible are all part of the human skull. The Frontal bone forms the forehead, the Occipital bone forms the back and base of the skull, and the Mandible is the lower jawbone.
Step 3: Recognize that the Scapula is not part of the human skull. The Scapula, also known as the shoulder blade, is a flat triangular bone located in the upper back and is part of the appendicular skeleton, not the axial skeleton (which includes the skull).
Step 4: Compare the anatomical locations and functions of the listed bones. The Frontal bone, Occipital bone, and Mandible are involved in protecting the brain and forming the structure of the face, while the Scapula is involved in shoulder movement and arm attachment.
Step 5: Conclude that the Scapula is the correct answer to the question, as it is not a bone of the human skull.
