The squamosal suture is located where the parietal and temporal bones meet on the lateral side of the skull. 

The neurocranium is the part of the skull that forms a protective covering around the brain. The other part of the skull is the facial skeleton, which forms the bones of the face. The vomer bone is not part of the neurocranium, rather it forms the inferior part of the nasal septum. 

All answer choices are found on the ethmoid bone, except for the mastoid process, which is found on the temporal bone.

The stapes is "U"-shaped and is the smallest bone in the body located in the outer ear. The stapes, malleus, and incus (collectively known as the ossicles) convey sound to the inner ear. The hyoid is also "U"-shaped, but it is larger and located in the throat not the skull. The mandible is located in the skull and is "U"-shaped, but is massive in comparison to the stapes because the ossicles could all fit on a penny. The maxilla is not "U"-shaped.

The foramen magnum is the large hole through which the spinal cord passes connecting the spinal cord to the brainstem. The small holes that connect the nasal cavity to the brain are referred to as the cribriform plate. The internal auditory meatus are the holes in the side of the the head that allow sound to enter the ear canal. The jugular veins enter the skull through the jugular foramen, which is formed between the connection of the temporal and occipital bones.

The frontal bone if the skull bone that is the most anterior and superior bone of the skull. It is the bone located in the forehead region of the face. The parietal bones are located on each side of the skull, near the ears. The occipital bone is located in the posterior and inferior aspect of the skull. The zygomatic bone is responsible for forming the cheekbones underneath the orbits.

The mandible is the lower jaw bone that forms the chin and jawline. The zygomatic bone forms cheekbones, the nasal bone forms the nose. The ears are formed from cartilage and have no bones in the visible portions.

The sagittal suture is the longest suture in the skull and runs from the frontal bone, between the parietal bones, to the lambdoid suture. The lambdoid suture is the suture that forms between the parietal and occipital bones. There are no major sutures in the facial bones. 

The lacrimal bone is located in the orbit, nearest the nasal cavity. The sphenoid bone is located behind the eyes. The mandible makes up the lower jaw. Finally, the occipital bone is located in the posterior aspect of the skull.

The stapes, or stirrup, is the ossicle closest to the skull. It is the last bone in the "chain" of ossicles. The incus, also known as the anvil, is the middle bone. The malleus, or hammer, is the most distal bone from the skull.
