If you examined an x-ray of a wrist and noticed the epiphyseal lines were closed, what could you conclude about this individual?

a. The person has not reached puberty.

b. Intramembranous ossification closed the epiphyseal lines.

c. The person is post-pubescent.

d. The blood supply has been cut off from the epiphyses.

Solution

Answer:

C.The person is post-pubescent.

Explaination: When a long bone stops growing in length, the epiphyseal plate (site of growth of a bone in length) becomes ossified and is formed the Epiphyseal Line. And the closed epiphyseal line is the indication of the attainment of full growth of long bone. In an individual, the closed epiphyseal lines only occur after a specific age i.e. after attainment of puberty or we can say it post-pubescent age.
