General Concepts of Growth (CF12-14)

Question 12 of 20 Question 1 of 20

1

The cranial vault develops via intramembranous ossification. The mandible and maxilla develop via endochondrial ossification.

Select one of the following:

  • First true, second false

  • First false, second true

  • Both false.

  • Both true

Explanation

Question 2 of 20 Question 2 of 20

1

The flat bones in our bodies develop via endochondrial ossification. The long bones of our bodies develop via intramembranous ossification.

Select one of the following:

  • Both false

  • First false, second true

  • Both true

  • First true, second false

Explanation

Question 20 of 20 Question 3 of 20

1

The resorption reversal line is where resorption takes place. Idiopathic condylar resportion causes a large overbite, open bite, and a smaller looking mandible.

Select one of the following:

  • Both true

  • First true, second false

  • Both false

  • First false, second true

Explanation

Question 5 of 20 Question 4 of 20

1

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.

Select one of the following:

  • First true, second false

  • Both false

  • Both true

  • First false, second true

Explanation

Question 19 of 20 Question 5 of 20

1

Which of the following is incorrect about mandibular development?

Select one of the following:

  • All of the above are correct

  • Horizontal expansion occurs via deposition on the external side

  • Deposition occurs at the condylar surface and coronoid process

  • Resorption occurs at the anterior of the ramus and gonial angle

  • Deposition makes the mandible grow upward and backwards

Explanation

Question 17 of 20 Question 6 of 20

1

Which of the following is correct about remodeling of the maxilla?

Select one of the following:

  • The anterior surfaces of the maxilla have deposition

  • Resorption of the endochondral or endosteal section of the cortical plate

  • Resorption on the periosteal surface of the palatal surface

  • none of the above

  • Deposition in the nasal base

Explanation

Question 6 of 20 Question 7 of 20

1

Drifting, relocation, and V principle occur simultaneously. The mandible moves downward and forward because of anterior apposition?

Select one of the following:

  • Both true

  • First false, second true

  • First true, second false

  • Both false

Explanation

Question 11 of 20 Question 8 of 20

1

Which of the following is incorrect?

Select one of the following:

  • 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

  • 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

  • Longitudinal studies allow estimation of the mean rate of growth for a population

  • Cross sectional studies contain variability which may conceal details of growth

Explanation

Question 3 of 20 Question 9 of 20

1

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.

Select one of the following:

  • Both true

  • First true, second false

  • Both false

  • First false, second true

Explanation

Question 13 of 20 Question 10 of 20

1

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.

Select one of the following:

  • Both statements are true

  • First true, second false

  • Both false

  • First false, second true

Explanation

Question 16 of 20 Question 11 of 20

1

At infancy the head is roughly a third of the body's total length. Similarly, the face makes up about half of the head.

Select one of the following:

  • First false, second true

  • First true, second false

  • Both false

  • Both true

Explanation

Question 7 of 20 Question 12 of 20

1

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.

Select one of the following:

  • Both false

  • First false, second true

  • First true, second false

  • Both true

Explanation

Question 18 of 20 Question 13 of 20

1

Which of the following is NOT a consequence of mouth breathing?

Select one of the following:

  • Mandible downward and forward

  • Irritation of the gums

  • Higher risk of caries

  • Open bite

  • Periodontal disease

Explanation

Question 8 of 20 Question 14 of 20

1

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.

Select one of the following:

  • Both true

  • First true, second false

  • First false, second true

  • Both false

Explanation

Question 4 of 20 Question 15 of 20

1

Menarche in females occurs after the peak velocity of growth. Males tend to have their peak growth velocity before females.

Select one of the following:

  • First false, second true

  • First true, second false

  • Both true

  • Both false

Explanation

Question 15 of 20 Question 16 of 20

1

Chronological age is a good indicator of individual growth status. Growth is complete when the sesamoid bone is present.

Select one of the following:

  • Both true

  • First false, second true

  • First true, second false

  • Both false

Explanation

Question 1 of 20 Question 17 of 20

1

Which of the following is incorrect?

Select one of the following:

  • 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

Explanation

Question 14 of 20 Question 18 of 20

1

The functional matrix is soft tissue to include the cartilage and ligaments. The skeletal units includes the bone.

Select one of the following:

  • Both true

  • Both false

  • First false, second true

  • First true, second false

Explanation

Question 9 of 20 Question 19 of 20

1

A growth site is where growth is initiated. A growth center is a reactive place where growth occurs.

Select one of the following:

  • Both true

  • First false, second true

  • Both false

  • First true, second false

Explanation

Question 10 of 20 Question 20 of 20

1

  • Both true

  • First true, second false
