Example Questions
Example Question #394 : Gross Anatomy
Which structure separates the parietal bones from the occipital bone?
None of these
Coronal suture
Lambdoid suture
Inferior nuchal line
Sagittal suture
Lambdoid suture
The lambdoid suture is located between the parietal bones and the occipital bone. When looked at with the sagittal suture from a posterior view, it creates a lambda shape.
Example Question #62 : Identifying Bones Of The Skull
Which of the following is not a part of the ethmoid bone?
Perpendicular plate
Crista galli
Middle nasal concha
Pterygoid processes
Cribriform plate
Pterygoid processes
The pterygoid processes are inferior projections from the greater wings of the sphenoid bone. They attach to muscles that help with mastication.
Example Question #63 : Identifying Bones Of The Skull
Which cranial bone forms the posterior base of the skull?
Occipital
Parietal
Frontal
Temporal
Mandible
Occipital
The occipital bone is located at the posterior aspect of the head, inferior to the parietal bones. It contains a large opening called the foramen magnum which allows connection of the brain and spinal cord.
Example Question #191 : Bones
Which of the following is not an opening of the sphenoid bone?
Supraorbital notch
Foramen ovale
Foramen rotundum
Foramen spinosum
Optic canal
Supraorbital notch
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?
Parietal
Frontal
Temporal
Sphenoid
Ethmoid
Sphenoid
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?
Coronal suture
Occipital suture
Squamous suture
Zygomatic suture
Lambdoid suture
Coronal suture
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?
Squamous suture
Occipital suture
Lambdoid suture
Coronal suture
Zygomatic suture
Squamous suture
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?"
Temporal bone
Frontal bone
Zygomatic bone
Parietal bone
Occipital bone
Frontal bone
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?"
Occipital bone
Parietal bone
Temporal bone
Zygomatic bone
Frontal bone
Zygomatic 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.
Example Question #65 : Identifying Bones Of The Skull
What bone of the skull is directly anterior to the parietal bone?
Occipital bone
Zygomatic bone
Temporal bone
Frontal bone
Mandible
Frontal 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.
