This image is a labeled diagram of the bones of the skull in lateral view (side view). The task is to identify and label the 18 numbered parts of the skull. Below is the correct identification for each number, along with a brief explanation:
---
1. Parietal bone
- One of the two large bones that form the top and sides of the skull.
2. Temporal bone
- Located on the side of the skull; contains the structures of the ear.
3. Occipital bone
- Forms the back and base of the skull; includes the foramen magnum where the spinal cord connects to the brain.
4. Squamous part of the temporal bone
- The flat, scale-like portion of the temporal bone above the ear.
5. Mastoid process
- A bony projection behind the ear; contains air cells and serves as an attachment point for neck muscles.
6. Zygomatic arch
- The bony arch formed by the zygomatic bone and temporal bone; forms the cheekbone.
7. Maxilla
- The upper jawbone; forms the upper teeth and part of the face.
8. Mandible
- The lower jawbone; the only movable bone of the skull.
9. Mental protuberance
- The chin area of the mandible.
10. Frontal bone
- Forms the forehead and the upper eye sockets (orbits).
11. Coronal suture
- The joint between the frontal bone and the parietal bones.
12. Sagittal suture
- The joint between the two parietal bones at the midline of the skull.
13. Supraorbital foramen
- Opening above the eye socket; allows passage of nerves and blood vessels.
14. Infraorbital foramen
- Opening below the eye socket; transmits the infraorbital nerve.
15. Zygomatic bone
- Forms the prominence of the cheek and part of the eye socket.
16. Alveolar process of the maxilla
- Part of the maxilla that holds the upper teeth.
17. Mandibular condyle
- The rounded end of the mandible that articulates with the temporal bone to form the temporomandibular joint (TMJ).
18. Mandibular angle
- The posterior, inferior corner of the mandible.

This labeling helps in understanding cranial anatomy, which is essential in fields like medicine, biology, and anthropology. Let me know if you'd like a visual guide or mnemonic to remember these!
