question
Which of the following bones is not a facial bone? Inferior nasal concha Maxillary Ethmoid Zygomatic
answer
Ethmoid ~ 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? Nasal Zygomatic Inferior nasal concha Maxillary
answer
Maxillary ~ 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? Maxillary Lacrimal Zygomatic Nasal
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.
question
What is the anatomical name for the facial bones known as "cheekbones"? Zygomatic bones Lacrimal bones Nasal bones Maxillary bones
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? Nasal Zygomatic Lacrimal Maxillary
answer
Maxillary ~ 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. Zygomatic Inferior nasal concha Lacrimal Palatine
answer
Lacrimal
question
Which of the following is a function of the axial skeleton? Which of the following is a function of the axial skeleton? to hold the head upright to conduct respiratory inspirations to stabilize the lower limbs for standing All of these are functions of the axial skeleton.
answer
All of these are functions of the axial skeleton.
question
Which statement correctly describes the zygomatic arch? Which statement correctly describes the zygomatic arch? The arch is formed by the maxilla and zygomatic bones. The zygomatic bone has a temporal process. The zygomatic arch is superior to the squamosal portion of the temporal bone. The zygomatic process of the arch extends from the maxilla.
answer
The zygomatic bone has a temporal process.
question
In the labeling activity, which bones articulate with the parietal bone? ethmoid, maxilla, temporal zygomatic, frontal, occipital sphenoid, temporal, occipital frontal, occipital, maxilla
answer
sphenoid, temporal, occipital
question
Which correctly describes the temporal bone? Muscles that attach to the mastoid process move the jaw. The styloid process is superior to the external auditory meatus. It forms the only articulation with the mandible. The temporal bone articulates with all of the cranial bones.
answer
It forms the only articulation with the mandible.
question
The two bones that contain alveolar processes are the __________. mandible and vomer zygomatic and temporal palatine and maxilla maxilla and mandible
answer
maxilla and mandible
question
Which of the following structures passes through the foramen magnum? internal jugular veins optic nerves internal carotid arteries spinal cord
answer
spinal cord
question
Which of following does NOT form the orbit of the eye? ethmoid nasal sphenoid zygomatic
answer
nasal
question
The mandible ________. has a mental foramen for nerves that innervate the teeth forms a joint with the maxilla has a condylar process for attachment of the temporalis muscle has an anterior mental protuberance
answer
has an anterior mental protuberance
question
Which of the following is NOT a facial bone? ethmoid zygomatic mandible palatine
answer
ethmoid ~ The ethmoid is considered a cranial bone.
question
Which of the following is true? The middle nasal concha arises from the ethmoid bone. The inferior portion of the sphenoid bone forms the superior nasal concha. The nasal concha are located on the medial wall of the nasal cavity. All of the nasal concha are part of the same bone.
answer
The middle nasal concha arises from the ethmoid bone.
question
Which bones make up the nasal septum, which divides the left nostril from the right? vomer and maxilla the frontal, sphenoid, and maxillary sinuses the frontal bone, sphenoid bone, and ethmoid bone ethmoid and vomer
answer
ethmoid and vomer
question
How many pairs of ribs articulate directly with the sternum? 7 12 5 8
answer
7 ~ There are 7 pairs of true ribs in the human body. True ribs articulate directly with the sternum.
question
How many ribs are considered false ribs? How many ribs are considered false ribs? 7 8 5 12
answer
5 ~ 5 pairs of ribs are false ribs. False ribs either attach to the sternum indirectly by articulating with the costal cartilage of the rib above it, or do not attach to the sternum at all.
question
How many ribs make up the rib cage? How many ribs make up the rib cage? 12 24 10 8
answer
24 ~ The rib cage is composed of 12 pairs of ribs, 24 ribs in total. The 12 pairs of ribs articulate with the thoracic vertebrae posteriorly.
question
Identify the part of a rib that articulates in the demi-facets of the thoracic vertebra. Tubercle Head Neck Tuberosity
answer
head ~ The head of a rib articulates in a region between 2 thoracic vertebrae, contacting the inferior demi-facet of the top vertebra, and the superior demi-facet of the bottom vertebra. The neck of a rib is located between the head and tubercle. This area extends out towards the transverse process of a vertebra.
question
Identify the region of a rib that articulates with the transverse process of a vertebra. Shaft Head Neck Tubercle
answer
Tubercle ~ The tubercle of a rib is located between the neck and shaft of the rib at the proximal end of the bone. It contacts the transverse process at the transverse costal facet.
