- Frontal Bone: The bone located at the forehead; it forms the anterior part of the skull and the upper part of the eye sockets.
- Temporal Bone: Found on the sides and base of the skull; it houses structures of the inner ear and is involved in the jaw joint.
- Sphenoid Bone: Known as the "keystone" of the cranial floor, it connects with many other bones and has a complex shape that contributes to the skull's overall strength.
- Nasal Bone: A small bone that forms the bridge of the nose; it is paired and contributes to the shape of the face.
- Zygomatic Bone: Commonly known as the cheekbone; it articulates with the frontal, temporal, and maxillary bones, forming part of the orbit.
- Nasal Septum: The structure that divides the nasal cavity into two nostrils, composed of bone and cartilage; key for airflow regulation.
- Maxilla: The upper jaw bone that forms the central part of the facial skeleton; it holds the upper teeth and assists in forming parts of the orbit.
