Example Question #161 : Bones
Which of the following bones of the human cranium is paired, rather than single?
Ethmoid bone
Lacrimal bone
Frontal bone
Sphenoid bone
Mandible
Lacrimal bone
The lacrimal bone is a small, paired bone situated at the front part of the medial wall of the orbit, assisting with tear translocation. The frontal, sphenoid, and ethmoid bones and the mandible are all single bones.
Example Question #162 : Bones
Which of the following is not a bone of the human cranium?
Sphenoid bone
Vomer bone
Ethmoid bone
Os coxa
Palatine bone
Os coxa
The os coxa, commonly referred to as the hip bone, is not a bone of the human cranium. The palatine, vomer, and ethmoid bone, as well as the sphenoid, all constitute parts of the human cranium.
Example Question #162 : Bones
Which of the following bones of the human cranium form, when joined together, the sides and roof of the cranium?
Frontal bones
Zygomatic bones
Parietal bones
Occipital bones
Temporal bones
Parietal bones
When joined together, the parietal bones form the sides and roof of the cranium. There is only one frontal bone and one occipital bone. The zygomatic bones (cheekbones) are on the anterior aspect of the skull.
Example Question #163 : Bones
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?
Occipital bone
Sphenoid
Parietal bone
Vomer bone
Lacrimal bone
Sphenoid
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 #164 : Bones
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?
Zygomatic bone
Vomer bone
Maxilla
Nasal bone
Manubrium
Vomer bone
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 #164 : Bones
Which of the following cranial bones, when paired, form the upper jaw and palate of the mouth?
Mandible
Sphenoid bone
Zygomatic bone
Frontal bone
Maxilla
Maxilla
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?
Sphenoid bone
Nasal bones
Temporal bones
Zygomatic bones
Maxillae
Nasal bones
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 #167 : Bones
Which of the following bones of the human cranium consists of a squamous, orbital, and nasal part and correlates roughly to the "forehead"?
Vomer bone
Temporal bone
Parietal bone
Occipital bone
Frontal bone
Frontal bone
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 #165 : Bones
Which of the following bones of the human cranium is single, rather than paired?
Maxilla
Temporal bone
Zygomatic bone
Occipital bone
Parietal bone
Occipital bone
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 #169 : Bones
Which of the following bones of the human cranium articulates with the frontal, sphenoid, and temporal bones, as well as the maxillae?
Nasal bone
Mandible
Zygomatic bone
Occipital bone
Parietal bone
Zygomatic bone
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.
