Final answer:
True, most human bones start as cartilage at birth and are later ossified into bone. Also, a broken bone is indeed the same condition as a bone fracture, the terms are used interchangeably.
Step-by-step explanation:
The statement that most bones are made entirely of cartilage at birth is True. In humans, the skeletal system initially develops as cartilage, and as a baby grows, this cartilage is gradually replaced by bone in a process known as ossification. This is necessary for providing the flexibility needed for birth and rapid growth.
Regarding the statement that a broken bone is the same as a bone fracture, this is also True. The term fracture is the clinical term used by medical professionals, while broken bone is the layman's term. Both refer to the same condition, where the continuity of the bone is disrupted.
