Example Questions

Example Question #191 : Bones

Which of the following is not an opening of the sphenoid bone?

Possible Answers:

Supraorbital notch

Foramen ovale

Foramen rotundum

Foramen spinosum

Optic canal

Correct answer:

Supraorbital notch

Explanation:

The supraorbital notch is located on the frontal bone at the superior and medial margin of the orbit, whereas the sphenoid bone makes up part of the inner bony orbit.

Example Question #65 : Identifying Bones Of The Skull

Which bone of the skull articulates with all the others listed?

Possible Answers:

Parietal

Frontal

Temporal

Sphenoid

Ethmoid

Correct answer:

Sphenoid

Explanation:

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.

Example Question #61 : Identifying Bones Of The Skull

What suture separates the frontal and parietal bones?

Possible Answers:

Coronal suture

Occipital suture

Squamous suture

Zygomatic suture

Lambdoid suture

Correct answer:

Coronal suture

Explanation:

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

Example Question #62 : Identifying Bones Of The Skull

What is the suture that separates the temporal and parietal bones in the skull?

Possible Answers:

Squamous suture

Occipital suture

Lambdoid suture

Coronal suture

Zygomatic suture

Correct answer:

Squamous suture

Explanation:

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.

Example Question #63 : Identifying Bones Of The Skull

What bone makes up your "forehead?"

Possible Answers:

Temporal bone

Frontal bone

Zygomatic bone

Parietal bone

Occipital bone

Correct answer:

Frontal bone

Explanation:

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."

Example Question #64 : Identifying Bones Of The Skull

What bone makes up the "cheek bone?"

Possible Answers:

Occipital bone

Parietal bone

Temporal bone

Zygomatic bone

Frontal bone

Correct answer:

Zygomatic bone

Explanation:

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.

Example Question #65 : Identifying Bones Of The Skull

What bone of the skull is directly anterior to the parietal bone?

Possible Answers:

Occipital bone

Zygomatic bone

Temporal bone 

Frontal bone

Mandible

Correct answer:

Frontal bone

Explanation:

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.

Example Question #71 : Identifying Bones Of The Skull

What bone is posterior to the parietal bone?

Possible Answers:

Occipital bone

Temporal bone

Zygomatic bone

Mandible

Frontal bone

Correct answer:

Occipital bone

Explanation:

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.

Example Question #72 : Identifying Bones Of The Skull

What bone is directly anterior to the temporal bone?

Possible Answers:

Frontal bone

Parietal bone

Sphenoid bone

Mandible

Occipital bone

Correct answer:

Sphenoid bone

Explanation:

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.

Example Question #73 : Identifying Bones Of The Skull

What bone is directly posterior to the temporal bone?

Possible Answers:

Sphenoid bone

Mandible

Occipital bone

Frontal bone

Parietal bone

Correct answer:

Occipital bone

Explanation:

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.
