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.

Example Question #74 : Identifying Bones Of The Skull

What bone attaches and is directly inferior to the temporal bone?

Possible Answers:

Sphenoid bone

Occipital bone

Mandbile

Parietal bone

Frontal bone

Correct answer:

Mandbile

Explanation:

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.

Example Question #75 : Identifying Bones Of The Skull

When looking at the skull "face on" what bone is directly superior to the nasal bone?

Possible Answers:

Occipital bone

Parietal bone

Maxilla

Mandible

Frontal bone

Correct answer:

Frontal bone

Explanation:

The frontal bone is directly superior to the nasal bone when looking at the skull "face on." The Maxilla is directly inferior to the nasal bone. The mandible is inferior to the maxilla and therefore is inferior to the nasal bone. The parietal bone is superior to the nasal bone, but is posterior to the frontal bone and therefore it is not directly superior to the nasal bone. The occipital bone is located on the back of the skull and is therefore not directly superior to the frontal bone.

Example Question #76 : Identifying Bones Of The Skull

What bone is directly medial to the zygomatic bone?

Possible Answers:

Maxilla

Frontal bone

Occipital bone

Temporal bone

Mandible

Correct answer:

Maxilla

Explanation:

The maxilla is directly medial to the zygomatic bone. The mandible is inferior to the zygomatic bone. The frontal bone is superior to the zygomatic bone. The occipital bone is in the back of the skull and is therefore not directly medial to the zygomatic bone. The temporal bone is posterior to the zygomatic bone.

Example Question #77 : Identifying Bones Of The Skull

What suture separates the parietal and the occipital bones?

Possible Answers:

Lambdoid suture

Occipital suture

Coronal suture

Zygomatic suture

Squamous suture

Correct answer:

Lambdoid suture

Explanation:

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.
