Question

consider the development of a long bone, like the femur. which statement does not describe this bone development? a long bones start as hyaline cartilage. b secondary ossification occurs after birth in the epiphysis of bones. c bones continue to grow in length at the epiphyseal plate until puberty. d primary ossification starts in the center of the diaphysis of long bones prior to birth.

Explanation:

• Option A: Long bones do start as hyaline cartilage models (endochondral ossification).
• Option B: Secondary ossification centers form in the epiphysis after birth.
• Option C: Bones grow in length at the epiphyseal plate until the plate closes (usually around puberty - but the closure is not exactly at puberty onset, it's a process that can finish a bit later. However, this is a common simplification in basic anatomy).
• Option D: Primary ossification centers form in the diaphysis (shaft) of long bones before birth.

Answer:

C. Bones continue to grow in length at the epiphyseal plate until puberty.
