Example Questions

Example Question #371 : Human Anatomy And Physiology

Which of the following is the relatively small, butterfly-shaped bone of the human cranium, situated in the middle of the skull, in front of the temporal bone?

Possible Answers:

Occipital bone

Sphenoid

Lacrimal bone

Vomer bone

Parietal bone

Correct answer:

Sphenoid

Explanation:

The sphenoid is the relatively small, butterfly-shaped bone situated in the middle of the skull, in front of the temporal bone. There are many foramina in the sphenoid bone and its intricacies should be studied closely. The vomer is one of two bones that make up the nasal septum.

Example Question #372 : Human Anatomy And Physiology

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?

Possible Answers:

Nasal bone

Zygomatic bone

Vomer bone

Maxilla

Manubrium

Correct answer:

Vomer bone

Explanation:

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.

Example Question #373 : Human Anatomy And Physiology

Which of the following cranial bones, when paired, form the upper jaw and palate of the mouth?

Possible Answers:

Mandible

Maxilla

Sphenoid bone

Frontal bone

Zygomatic bone

Correct answer:

Maxilla

Explanation:

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.

Example Question #166 : Bones

Which of the following are two small oblong bones of the human cranium that form the "bridge" of the nose?

Possible Answers:

Sphenoid bone

Maxillae

Temporal bones

Zygomatic bones

Nasal bones

Correct answer:

Nasal bones

Explanation:

The nasal bones are two small oblong bones that form the "bridge" of the nose. They tend to vary in size and shape in different individuals.

Example Question #374 : Human Anatomy And Physiology

Which of the following bones of the human cranium consists of a squamous, orbital, and nasal part and correlates roughly to the "forehead"?

Possible Answers:

Vomer bone

Frontal bone

Temporal bone

Occipital bone

Parietal bone

Correct answer:

Frontal bone

Explanation:

The frontal bone consists of a squamous, orbital, and nasal part and refers generally to the part of the body known as the "forehead"?

Example Question #375 : Human Anatomy And Physiology

Which of the following bones of the human cranium is single, rather than paired?

Possible Answers:

Temporal bone

Occipital bone

Maxilla

Parietal bone

Zygomatic bone

Correct answer:

Occipital bone

Explanation:

The occipital bone is a single, saucer-shaped bone located at the back and lower part of the skull. The parietal, temporal, and zygomatic bones, as well as the maxilla, are all paired bones; the two halves of each are located opposite one another along the midsagittal plane.

Example Question #376 : Human Anatomy And Physiology

Which of the following bones of the human cranium articulates with the frontal, sphenoid, and temporal bones, as well as the maxillae?

Possible Answers:

Nasal bone

Zygomatic bone

Parietal bone

Mandible

Occipital bone

Correct answer:

Zygomatic bone

Explanation:

The zygomatic bone, also referred to as the cheekbone, articulates with four bones: the frontal, sphenoid, temporal, and maxillae. The nasal bone articulates with the frontal bone, ethmoid bone, and the maxilla. The mandible articulates with the temporal bones. The occipital bone articulates with the two temporal bones, the two parietal bones, the sphenoid bone, and the atlas. The parietal bone articulates with the frontal bone, the temporal bones, and the occipital bone.

Example Question #377 : Human Anatomy And Physiology

Which of the following bones of the human cranium is situated at the sides and base of the skull and houses the structures of the organ of hearing?

Possible Answers:

Zygomatic bone

Parietal bone

Occipital bone

Maxillae

Temporal bone

Correct answer:

Temporal bone

Explanation:

The temporal bones are situated at the sides and base of the skull and house the structures of the organ of hearing. They are called temporal bones because the anatomists coining such terms were beginning to get gray hair, and they noticed that the grey hair always shows up first (temporally) on the sides of the head - in the temporal region. 

Example Question #45 : Identifying Bones Of The Skull

What is the dental formula for a modern human child?

Possible Answers:

2:1:1:2

2:1:2:3

2:1:0:2

2:1:3

2:1:1:2

Correct answer:

2:1:0:2

Explanation:

The dental formula for a modern human child is 2:1:0:2 in each quadrant: two incisors, one canine, and two molars, for a total of 20 deciduous teeth. There are no premolars in deciduous dentition.

Example Question #378 : Human Anatomy And Physiology

What suture ties together the occipital and two parietal bones on the posterior cranium?

Possible Answers:

coronal suture

Squamosal suture

basilar suture

sagittal suture

Lambdoidal suture

Correct answer:

Lambdoidal suture

Explanation:

The lambdoidal suture ties together the occipital and two parietal bones on the posterior cranium.

The sagittal suture runs along the top of the cranium, between the two parietal bones. The coronal suture runs laterally from the top of the cranium and ties together the frontal and two parietal bones. The squamosal suture is the area where the squamosal section of the temporal bone is beveled and overlaps the parietal bone. The basilar suture, also referred to as spheno-occipital synchondrosis, is a suture between the occipital and sphenoid bones.
