Resource summary

Question 1

Question
The cranial vault develops via intramembranous ossification. The mandible and maxilla develop via endochondrial ossification.
Answer
  • Both true
  • First true, second false
  • First false, second true
  • Both false.

Question 2

Question
The flat bones in our bodies develop via endochondrial ossification. The long bones of our bodies develop via intramembranous ossification.
Answer
  • Both true
  • First true, second false
  • First false, second true
  • Both false

Question 3

Question
The resorption reversal line is where resorption takes place. Idiopathic condylar resportion causes a large overbite, open bite, and a smaller looking mandible.
Answer
  • Both true
  • First true, second false
  • First false, second true
  • Both false

Question 4

Question
Secondary displacement is the movement of a bone and its soft tissues not related to its own enlargement. Growth of the middle cranial fossa and the temporal lobe directs the nasomaxillary complex downward and forward.
Answer
  • Both true
  • First true, second false
  • First false, second true
  • Both false

Question 5

Question
Which of the following is incorrect about mandibular development?
Answer
  • Resorption occurs at the anterior of the ramus and gonial angle
  • Deposition occurs at the condylar surface and coronoid process
  • Deposition makes the mandible grow upward and backwards
  • Horizontal expansion occurs via deposition on the external side
  • All of the above are correct

Question 6

Question
Which of the following is correct about remodeling of the maxilla?
Answer
  • Resorption on the periosteal surface of the palatal surface
  • The anterior surfaces of the maxilla have deposition
  • Deposition in the nasal base
  • Resorption of the endochondral or endosteal section of the cortical plate
  • none of the above

Question 7

Question
Drifting, relocation, and V principle occur simultaneously. The mandible moves downward and forward because of anterior apposition?
Answer
  • Both true
  • First true, second false
  • First false, second true
  • Both false

Question 8

Question
Which of the following is incorrect?
Answer
  • Longitudinal studies allow for accurate prediction of adult height due to ability to see individual variations in the growth curve
  • Cross-sectional studies can be used to estimate mean rate of growth
  • Mixed longitudinal studies involve the short time of a cross sectional study and large sample size with subjects in different age groups to achieve data covering a greater span of ages
  • Cross sectional studies contain variability which may conceal details of growth
  • Longitudinal studies allow estimation of the mean rate of growth for a population

Question 9

Question
The distance curve is height plotted against time and the velocity curve is the rate of growth. Menarche occurs after the peak of the velocity curve.
Answer
  • Both true
  • First true, second false
  • First false, second true
  • Both false

Question 10

Question
The cranial base solidifies at 6-7 years of age. By adulthood, the head is roughly 1/8th of the total height and legs make up roughly half.
Answer
  • Both statements are true
  • First true, second false
  • First false, second true
  • Both false

Question 11

Question
At infancy the head is roughly a third of the body's total length. Similarly, the face makes up about half of the head.
Answer
  • Both true
  • First true, second false
  • First false, second true
  • Both false

Question 12

Question
According to Scammon's curve, the lymphoid tissues reach roughly double the adult size near 10 years of age. The genitals reach their full size during the onset of puberty.
Answer
  • Both true
  • First true, second false
  • First false, second true
  • Both false

Question 13

Question
Which of the following is NOT a consequence of mouth breathing?
Answer
  • Periodontal disease
  • Higher risk of caries
  • Open bite
  • Mandible downward and forward
  • Irritation of the gums

Question 14

Question
There is more variation in height than weight measurement. Peak velocity for weight spurt leads the peak velocity for height by an average of 3 months.
Answer
  • Both true
  • First true, second false
  • First false, second true
  • Both false

Question 15

Question
Menarche in females occurs after the peak velocity of growth. Males tend to have their peak growth velocity before females.
Answer
  • Both true
  • First true, second false
  • First false, second true
  • Both false

Question 16

Question
Chronological age is a good indicator of individual growth status. Growth is complete when the sesamoid bone is present.
Answer
  • Both true
  • First true, second false
  • First false, second true
  • Both false

Question 17

Question
Which of the following is incorrect?
Answer
  • In sutural growth theory, the sutures are the primary growth sites.
  • Primary cartilage theory states that periosteum and cartilage are primary growth sites
  • The condyle of the mandible considered the pacemaker of growth for mandibular development in primary cartilage theory
  • The nasal septum is not a growth center
  • Growth of the skull follows growth of the brain

Question 18

Question
The functional matrix is soft tissue to include the cartilage and ligaments. The skeletal units includes the bone.
Answer
  • Both true
  • First true, second false
  • First false, second true
  • Both false

Question 19

Question
A growth site is where growth is initiated. A growth center is a reactive place where growth occurs.
Answer
  • Both true
  • First true, second false
  • First false, second true
  • Both false

Question 20

Question
Teeth are part of the skeletal unit. Muscles are part of the functional matrix.
Answer
  • Both true
  • First true, second false
  • First false, second true
  • Both false
