The Correct Answer and Explanation is:
Based on the image provided, which is a lateral view of the human skull with some cranial bones highlighted, here is the correct labeling of the bones:
Correct Labels:
- Top left – Parietal bone
- Top right – Frontal bone
- Middle left – Occipital bone
- Middle right (blue) – Temporal bone
- Bottom left (green) – Sphenoid
- Bottom center (purple) – Ethmoid
Explanation
The human skull is made up of several bones that protect the brain and form the structure of the face. In this lateral view of the skull, we are focusing on the cranial bones. Here’s a breakdown of each one shown in the image:
- Frontal Bone – This bone forms the forehead and the upper part of the eye sockets. In this lateral view, it’s the frontmost bone, marked in the top right.
- Parietal Bone – These are paired bones that form the upper sides and roof of the cranium. In the image, the visible parietal bone is located at the top left portion of the skull.
- Occipital Bone – Located at the back of the skull, this bone surrounds the foramen magnum (where the spinal cord connects to the brain). In this image, it is situated in the lower left part.
- Temporal Bone – These bones are located at the sides and base of the skull and house the structures of the ears. On this view, it is the large, blueish bone toward the lower right middle section of the skull.
- Sphenoid Bone – This butterfly-shaped bone is situated at the base of the skull in front of the temporal bones and basilar part of the occipital bone. In this image, it appears green and is just anterior to the temporal bone.
- Ethmoid Bone – This bone forms part of the nasal cavity and the medial wall of the orbits. In this side view, it appears small and purple, located near the center base of the skull.
Understanding these bones helps in fields like anatomy, medicine, and forensic science, where knowledge of skull structure is essential.
