Example Questions

Example Question #201 : Bones

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

Possible Answers:

Sphenoid bone

Parietal bone

Mandbile

Frontal bone

Occipital 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 #202 : Bones

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

Possible Answers:

Mandible

Parietal bone

Frontal bone

Occipital bone

Maxilla

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 #203 : Bones

What bone is directly medial to the zygomatic bone?

Possible Answers:

Occipital bone

Mandible

Frontal bone

Maxilla

Temporal bone

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 #411 : Gross Anatomy

What suture separates the parietal and the occipital bones?

Possible Answers:

Occipital suture

Zygomatic suture

Lambdoid suture

Coronal 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.
