question
Identify the general location of the zygomatic arch.
answer
cheek. The zygomatic arch is a bony bridge formed between the zygomatic and temporal bones. It contributes to the prominence of the cheek.
question
Identify the 2 bones that make up the zygomatic arch.
answer
Zygomatic bone and temporal bone. The temporal process of the zygomatic bone and the zygomatic process of the temporal bone fuse to form the zygomatic arch.
question
Identify the region on the temporal bone that forms much of the zygomatic arch.
answer
Zygomatic process. The zygomatic process is the name of the elongated projection that extends out from the temporal bone reaching towards the zygomatic bone, forming most of the zygomatic arch.
question
Identify the region on the zygomatic bone that forms part of the zygomatic arch.
answer
Temporal process. The temporal process of the zygomatic bone is a small bony projection that extends posteriorly to fuse with the zygomatic process of the temporal bone, forming the zygomatic arch.
question
Which of the following categories is the best fit for the zygomatic arch?
answer
Facial. Although the zygomatic bone is a facial bone and the temporal bone is a cranial bone, the zygomatic arch is best described as a facial structure.
question
Identify the location of the occipital bone.
answer
Posterior surface and base of the cranium. The occipital bone makes up the posterior part of the cranium
question
Name the opening in the occipital bone through which the spinal cord passes.
answer
Foramen magnum. The foramen magnum is the opening through which the spinal cord passes.
question
Identify the area of the occipital bone that articulates with the vertebral column.
answer
Occipital condyles. The occipital condyles are found on the inferior surface of the skull on either side of foramen magnum. They articulate with the first cervical vertebra, the atlas. This articulation allows us to flex and extend the skull in a nodding "yes" motion.
question
Identify the occipital bone landmark that can not be palpated from the surface of the head.
answer
The occipital condyles are found on either side of foramen magnum. They articulate with the atlas and can't be palpated on the head or neck.
question
Identify the large suture on the posterior surface of the skull at the border of the occipital bone.
answer
The lambdoid suture is found between the occipital bone and the parietal and temporal bones.
question
Which of the following bones is not a facial bone? Zygomatic Ethmoid Inferior nasal concha Maxillary
answer
The ethmoid bone forms the area of the cranium between the nasal cavity and the orbits
question
Which of the following facial bones contain a sinus? Maxillary Zygomatic Nasal Inferior nasal concha
answer
The maxillary bones contain the maxillary sinuses. They are the largest sinuses, located laterally to the nasal cavity in the region of the cheek.
question
Which facial bones makeup the central portion of the bridge of the nose? Nasal Maxillary Lacrimal Zygomatic
answer
Nasal. The 2 tombstone shaped nasal bones are found above the nasal cavity. They form a continuous bony bridge that connects the 2 sides of the face. Part D
question
What is the anatomical name for the facial bones known as "cheekbones"?
answer
Zygomatic bones. The zygomatic bones are known as the cheekbones. Together, the zygomatic bone and the temporal bone form the zygomatic arch. This region is the bony foundation of the facial prominence known as the cheek.
question
Which facial bones fuse to form the upper jaw?
answer
The fused maxillary bones are known as the maxilla, and form the upper jaw and part of the palate.
question
Identify the small facial bones found in the medial wall of the orbit.
answer
The lacrimal bone along with the sphenoid, ethmoid, and frontal bones make up the medial wall of the orbit.
