Question 9

Measurement of maturity status- evaluated in terms of 4 approaches. What are these?

Answer 9

1. Somatic characteristics (size for age charts, age from peak height velocity (PHV))
2. Sexual dev (appearance of secondary sex characteristics, age of menarche in girls (first menstrual cycle))
3. Skeletal dev (skeletal age)
4. Dental dev (dental age)

Question 10

Skeletal age
Assess developmental age using radiographs of the hand & wrist. There are 27 bones in the hand & wrist. By the shape characteristics & rate of ossification, one can assess the skeletal age of individuals rated to a normative system

Answer 10

True

Question 11

Define ossification (also known as osteogenesis)

Answer 11

The process of laying down new bone material by cells called osteoblasts

Question 12

What are the 3 different techniques for determining skeletal age?

Answer 12

Greulich -Pyle (uses an atlas for comparison)
This one is most commonly used

Tanner-Whitehouse (takes the mean of individually rated bones)

Roche-Fels

Question 13

Define somatic

Answer 13

Of the body

Question 14

Developmental variability is influenced by 2 factors. What are they?

Answer 14

1. Variation in the onset of puberty

2. Variation in the length of time taken to pass through all the stages of puberty

Question 15

Define intramembranous ossification

Answer 15

Is one of the two essential processes during fetal development of the mammalian skeleton system by which bone tissue is created

Question 16

Define endochondral ossification

Answer 16

Is one of the two essential processes during fetal development of the mammalian skeletal system by which bone tissue is created
