Identifying Bones of the Skull - Anatomy

The parietal bones (one on each side of the skull) form a shield-shaped dome across the top of the skull, creating most of the bulging sides and top of the cranium. The parietal bones are useful in distinguishing the skulls of modern man from Australopithecine ancestors. The bone has a large opening, the parietal foramen, through which blood supply and nerves enter.

The occipital bone forms the base of the skull, and contains the opening (foramen magnum) through which the thick nerve fibers that will form the spinal cord emerge. It houses the occipital lobe of the cerebrum, which is responsible for visual processing and holds the visual cortex.

The temporal bones (one on each side) form the mandibular fossae, which join the mandible to stabilize the jaw. The bone also forms part of the prominence of the cheek, the meatus for neck and tongue muscles, and contains the gap through which the ear is formed.

The frontal bone forms the "forehead" and anterior part of the superior skull. It contains the roof of the nasal cavity, the roof of the orbital sockets, and in some skeletons shows a bony notch or supraforamen.

The vomer bone is a small, unpaired bone of the human cranium, located along the midsagittal line. It articulates with the sphenoid, the ethmoid, and the palatine and maxillary bones. The vomer, along with the perpendicular plate of the ethmoid bone, makes up the nasal septum.

The maxillae form the upper jaw and palate of the mouth. The palatine bone also makes up the hard palate (roof) of the mouth, but it is a single bone, not a pair. The mandible is the lower jaw bone, and is also unpaired.

The correct answer is the squamous suture. It joins as a child develops and divides the temporal and parietal bones. The coronal suture separates the frontal bone and the parietal bones. The lambdoid suture separates the parietal and occipital bones. The zygomatic and occipital sutures do not exist.

The correct answer is the lambdoid suture. It joins as a child develops and divides the parietal and the occipital bones. The coronal suture separates the frontal and the parietal bones. The squamous suture separates the temporal and the parietal bones. The zygomatic and occipital sutures do not exist.

The bone that makes up your "forehead" is the frontal bone because it is the most anterior bone of the skull and is the underlying bone of the forehead. The parietal bone are posterior to the frontal bone and do not make up the forehead. The occipital bone is the most posterior bone of the skull and the zygomatic bone is inferior to the frontal bone and makes up the "cheek bone."

The "cheek bone" is the zygomatic bone and therefore is the correct answer. The occipital bone is in the back of the head. The frontal bone makes up the "forehead." The parietal bone is in the middle of the skull, posterior to the frontal bone but anterior to the occipital bone. The temporal bone is on the side of the head and is located inferior to the parietal bone.

The bone anterior to the parietal bone is the frontal bone. The occipital bone is posterior to the parietal bone. The temporal bone is inferior to the parietal bone.The zygomatic bone is antero-inferior to the parietal bone and is not directly anterior to it. The mandible is inferior to it and makes up the lower portion of the jaw.

The bone posterior to the parietal bone is the occipital bone. The frontal bone is anterior to the parietal bone. The temporal bone is inferior to the parietal bone. The zygomatic bone is antero-inferior to the parietal bone and is not directly anterior to it. The mandible is inferior to it and makes up the lower portion of the jaw.

The bone directly anterior to the temporal bone is the sphenoid bone. The frontal bone supero-anterior to the temporal bone but is not directly anterior to the temporal bone. The parietal bone is superior to the temporal bone. The occipital bone is posterior to the temporal bone. The mandible is inferior to the temporal bone.

The occipital bone is directly posterior the temporal bone and is the correct answer. The sphenoid bone is directly anterior to the temporal bone. The frontal bone is supero-anterior to the temporal bone. The parietal bone is superior to the temporal bone. The mandible is inferior to the temporal bone.

The mandible is directly inferior to the temporal bone and connects to it. The sphenoid bone is directly anterior to the temporal bone. The frontal bone is supero-anterior to the temporal bone. The parietal bone is superior to the temporal bone. The mandible is inferior to the temporal bone.

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 occipital bone is the bone responsible for forming the back of the skull and parts of the base of the skull. The other bones listed form other parts of the skull.

The sphenoid bone is a central wedge that spans across the cranial floor. It is shaped like a bat with its wings spread and articulates with every bone in the skull.

The skeletal system is divided into the axial skeleton and the appendicular skeleton. The axial skeleton consists of bones of the head, ribs, vertebral column, and sternum. In contrast, the appendicular skeleton consists of bones of the extremities, including the fingers, arms, and legs.
