question
A cleft palate arises when the right and left _____________ bones fail to fuse medially during fetal development. maxillae mandibles inferior nasal conchae middle nasal conchae
answer
maxillae The palatine processes of the maxillae form the anterior two-thirds of the hard palate.
Explanation: A cleft palate arises when the right and left maxillae bones fail to fuse medially during fetal development. This can happen if the bones do not form properly or if there is an interruption in their growth. Cleft palates can also occur as a result of other birth defects, such as those involving the mandibles or the inferior nasal conchae.
question
Which of the following is the only bone that normally moves in relation to the others? A B C D
answer
D- mandible The bone at D forms a joint with the temporal bone (temporomandibular joint) that allows the mouth to open, close, and move laterally.
question
Name the foramen at letter C. foramen magnum foramen lacerum jugular foramen foramen ovale
answer
Foramen magnum The foramen magnum ("great hole") is the largest foramen in the skull and provides passage for the spinal cord.
Explanation: The foramen magnum is the large opening at the base of the skull through which the spinal cord passes. The foramen lacerum is a small opening in the skull through which blood vessels and nerves pass. The jugular foramen is a large opening in the skull through which the jugular vein and nerves pass. The foramen ovale is a small opening in the skull through which blood vessels pass.
question
Which of the designated bones articulates with both the vomer and the nasal bones? A B C D
answer
C- Maxilla The maxilla articulates with both the nasal bone and the vomer.
Explanation: The answer is C, the ethmoid bone. The ethmoid bone is a small, spongy bone located at the base of the skull, behind the nose. It articulates with the vomer (a flat bone in the nasal cavity) and the nasal bones (two small bones in the upper part of the nose).
question
Identify the bone(s) that form(s) the majority of the hard palate and a keystone bone of the face. A B C D
answer
A These bones, along with the palatine bones, form the hard palate.
Explanation: The hard palate is formed by the palatine bones, which are a keystone bone of the face. The palatine bones are a pair of bones that form the back portion of the hard palate and the floor of the nasal cavity. They also form part of the walls of the orbits. The palatine bones are triangular in shape and have a number of foramina (holes) that allow for the passage of nerves and blood vessels.
question
Name the highlighted bone(s). maxillary bones, or maxillae mandible, or mandibular bone temporal bones zygomatic bones
answer
mandible, or mandibular bone This bone forms the lower jaw and contains half of your teeth.
Explanation: The highlighted bones are the maxillary bones, or maxillae. These are the bones that make up the upper jaw. The mandible, or mandibular bone, is the bone that makes up the lower jaw. The temporal bones are the bones that make up the sides of the head. The zygomatic bones are the bones that make up the cheekbones.
question
The highlighted bone articulates with which other bone(s) of the skull? temporal bone ethmoid bone zygomatic bones maxillary bones, or maxillae
answer
temporal bone The temporal bone bears a mandibular fossa that articulates with the condylar process of the mandible.
Explanation: The highlighted bone is the temporal bone, which articulates with the ethmoid bone, the zygomatic bones, and the maxillary bones (also called the maxillae).
question
The vomer and ethmoid bones form part of the __________. nasal septum lacrimal fossa lateral walls of the nasal cavity orbits
answer
nasal septum The vomer and ethmoid bones form the bony parts of the nasal septum. The vomer forms the inferior portion of the septum. The perpendicular plate of the ethmoid bone forms the superior portion of the septum.
Explanation: The vomer and ethmoid bones form part of the nasal septum, which is the bone and cartilage partition that divides the nasal cavity into the left and right sides. The vomer also forms part of the lateral walls of the nasal cavity, and the ethmoid bone forms part of the orbits, the bony cavities that house the eyes.
question
The suture that connects the two parietal bones together is the ________. squamous coronal lambdoid sagittal
answer
sagittal
question
The hyoid bone is unique because it ________. is the only irregular bone found in the neck is the only bone of the body that does not articulate with any other bone is the only bone formed by the fusion of right and left halves is composed of three bones joined together
answer
is the only bone of the body that does not articulate with any other bone
Explanation: The hyoid bone is unique because it is the only irregular bone found in the neck. The hyoid bone is also the only bone of the body that does not articulate with any other bone. The hyoid bone is formed by the fusion of right and left halves. The hyoid bone is also composed of three bones joined together.
question
Which bone forms the prominence of the cheek? sphenoid bone palatine bone temporal bone zygomatic bone
answer
zygomatic bone
Explanation:The hyoid bone is unique because it is the only irregular bone found in the neck. The hyoid bone is also the only bone of the body that does not articulate with any other bone. The hyoid bone is formed by the fusion of right and left halves. The hyoid bone is also composed of three bones joined together.
question
Which bone or pair of bones forms the superior portion of the cranium? the parietal bones the occipital bone the temporal bones the frontal bone
answer
the parietal bones
Explanation: The superior portion of the cranium is formed by the parietal bones, the occipital bone, the temporal bones, and the frontal bone.
question
The frontal bone articulates with the parietal bone by means of the sagittal suture.
answer
FALSE
Explanation: The frontal bone is the bone that forms the forehead. The parietal bone is the bone that forms the sides and top of the head. The sagittal suture is the line of union between the frontal and parietal bones.
question
If a herniated disc in the lumbar region is treated by surgically removing the intervertebral disc and doing a bone graft between the adjoining vertebrae, one of the consequences might be _________. reduced flexibility of the spine in the lower back gradual growth of a replacement intervertebral disc in the space between the vertebrae increased shock absorbance qualities in the intervertebral discs located immediately above and below the graft in order to compensate for the removal of the herniated disc All of the listed responses are correct.
answer
reduced flexibility of the spine in the lower back The intervertebral disc and space that it occupies provides room for vertebral bodies of adjacent vertebrae to flex and extend the vertebral column (spine).
question
A fracture of which structure is commonly referred to as "breaking your hip"? the ischium the head of the femur the neck of the femur the acetabulum
answer
the neck of the femur The neck of the femur is at risk because of the large percentage of spongy bone in the neck.
