Which of the bones of the skull forms most of the superior and lateral faces of the cranium?
Which of the bones of the skull forms most of the superior and lateral faces of the cranium?
Tap to reveal answer
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.

Which of the bones of the skull contains the openings and forms the anchors for the ears and jaw?
Tap to reveal answer
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.

Which bone of the skull forms the anterior covering for the brain, sinus cavities, and may contain a supraorbital notch?
Which bone of the skull forms the anterior covering for the brain, sinus cavities, and may contain a supraorbital notch?
Tap to reveal answer
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.

Which of the following is a small, unpaired bone of the human cranium, located along the midsagittal line, and articulating with the sphenoid, the ethmoid, and the palatine and maxillary bones?
Which of the following is a small, unpaired bone of the human cranium, located along the midsagittal line, and articulating with the sphenoid, the ethmoid, and the palatine and maxillary bones?
Tap to reveal answer
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.

Which of the following cranial bones, when paired, form the upper jaw and palate of the mouth?
Which of the following cranial bones, when paired, form the upper jaw and palate of the mouth?
Tap to reveal answer
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.

Tap to reveal answer
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.

What bone makes up your "forehead?"
What bone makes up your "forehead?"
Tap to reveal answer
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."

What bone makes up the "cheek bone?"
Tap to reveal answer
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.

Which bones are a part of the axial skeleton?
Which bones are a part of the axial skeleton?
Tap to reveal answer
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.
