Answer to Question 1

ANS: D
The epiphyseal cartilage plate is the area of active growth. Bone injury at the epiphyseal plate can significantly affect subsequent growth and development. Trauma or infection can result in deformity. The matrix, connective tissue, and calcified cartilage are not areas of active growth. Trauma in these sites will not result in growth problems for the long bones.

Answer to Question 2

ANS: D
At the time of the beginning of menstruation or the skeletal age of 13 years, most girls have grown to about 95 of their adult height. They may have some additional growth (5) until the epiphyseal plates are closed. Although growth cannot be definitively predicted, on average, 95 of adult height has been reached with the onset of menstruation. Pubertal growth spurt lasts about 1 year does not address the girl's question. Young women usually will grow approximately 5 more after the onset of menstruation.
