Peter is 10 years old and Paul is 34. Where would you find hyaline cartilage in Peter's long bones but not in Paul's?
medullary cavity
epiphyseal line
ends of the bones
epiphyseal plate
in periosteum
The Correct Answer is D
A. medullary cavity
This cavity holds marrow (red or yellow), not cartilage.
B. epiphyseal line
The epiphyseal line in adults is a remnant of the epiphyseal plate, but does not contain cartilage.
C. ends of the bones
Both Peter and Paul have articular hyaline cartilage at the ends of long bones for joint function.
D. epiphyseal plate
Only children like Peter have an epiphyseal plate (growth plate), which is made of hyaline cartilage. This area allows for bone lengthening during growth and becomes the epiphyseal line in adults like Paul.
E. in periosteum
The periosteum is a connective tissue membrane around bone-not cartilage.
