Which of the following is mismatched?
Periosteal arteries – supply the periosteum and outer part of the bone.
The nutrient arteries enter through Volkmann’s canals and supply the inner and outer part of the bone.
Metaphyseal arteries help to supply the red bone marrow and tissue of the metaphysis.
Epiphyseal arteries supply the epiphysis red bone marrow and tissue.

(a)
Which of the following statements is/are incorrect?
Intramembranous and endochondral ossification both involve replacement of preexisting connective tissue with bone.
Intramembranous ossification is the method by which flat bones of the skull, some facial bones, the mandible, and part of the clavicle are formed.
Endochondral ossification is the method by which most of the bones of the body are formed.
Endochondral ossification begins with development of an ossification center.
