Correct Answer is D
Explanation
Bone marrow is the soft, spongy tissue that fills the medullary cavity of long bones.
Bone marrow contains hematopoietic stem cells that produce blood cells, as well as fat cells and other supportive cells.
Choice A is incorrect because spongy bone is not the tissue that fills the medullary cavity, but the type of bone tissue that surrounds it.
Spongy bone has a porous structure that provides strength and flexibility to the bone.
Choice B is incorrect because compact bone is not the tissue that fills the medullary cavity, but the type of bone tissue that forms the outer wall of the diaphysis.
Compact bone has a dense and hard structure that provides protection and support to the bone.
Choice C is incorrect because none of these is not a valid answer.
The medullary cavity of long bones does contain a specific type of tissue, which is bone marrow.
Correct Answer is ["epiphyseal analysis"]
Explanation
The epiphysis is the rounded end of the femur that articulates with the hip bone and knee joint.
As a child grows, the epiphysis gradually fuses with the rest of the bone through a process called ossification.
By examining the degree of fusion of the epiphysis with the femur on an X-ray, doctors can estimate the age of the child.
In general, the younger the child, the less fused the epiphysis will be, and the easier it will be to determine the child's age.
However, it's important to note that this method provides only an approximate age range and cannot be used to determine an exact age.
