Bone marrow is the tissue that is in the center of large bones.
Answer given by: Nora
No, only a few large long bones (such as the femur and the humerus) and some large irregular bones (such as the crest of the ilium of the pelvis) have red marrow. Most bones have no marrow.
the foot bone
spongy bone
no. Blood cells are only formed in bone marrow. Flat bones do not have bone marrow.
There is yellow bone marrow and red bone marrow.
In the few flat bone you have red bone marrow. It contains the precursor cells of the haemopoietic tissue. They produce the red blood cells.

I think you are trying to ask about bone marrow. Bones are usually an off white. red bone marrow produces red and white blood cells and platelets. Yellow bone marrow stores body fat. But these are the only two types of bone marrow I know of.

At birth, all bone marrow is red. With age, more and more of it is converted to the yellow type. About half of adult bone marrow is red. Red marrow is found mainly in the flat bones, such as the hip bone, breast bone, skull, ribs, vertebrae and shoulder blades, and in the cancellous ("spongy") material at the epiphyseal ends of the long bones such as the femur and humerus. Yellow marrow is found in the hollow interior of the middle portion of long bones.
In a child all bone marrow is red bone marrow and can be found in nearly all flat and long bones, including the epiphysis and diaphysis. As the child ages the red bone marrow in the diaphysis of the long bones will be replaced with yellow bone marrow.
The red bone marrow makes red blood cells. The yellow bone marrow makes chemical energy.
Red bone marrow in the spongy/trabecular/cancellous bone in the ends of long bones.
In the centre cavities of all the bones in your body. (There's a lot in your legs, since the bones are quite big and have a large cavity). the bone marrow is located inside the bone in da middle of the bone. It is spongy. it is red when your a child, and turns yellow when your an adult. Bone marrow is the spongy tissue in the cavities of the bones. It is the blood cell 'factory'. Healthy bone marrow releases blood cells into the blood stream when they are mature and when required.
Bone marrow comes in two categories, red and yellow. Red is common in young children's bones. It creates red blood cells. As you become a teenager, you have less red and more yellow bone marrow. Yellow bone marrow stores fat so it can later be used as energy, but there are still some bones that contain red bone marrow.
