The top layer is called periosteum, which is a slippery thin tissue that covers the areas where tendons (the things that connect bone to muscle) and ligaments (the things that connect bone to bone).
Under that, there is a layer of compact bone, which is solid bone and very heavy.
Under the compact bone, there is spongy bone, which has little holes in it and looks somewhat like a sponge. This layer is not soft or squishy, even though you would expect it to be considering it's name. Spongy bone is lightweight, but serves the same purpose as compact bone, except is lighter and enables you to lift it.
In the larger bones, you would find bone marrow in the center of the bone. The red marrow manufactures blood cells, and the yellow marrow stores fat (the color of the marrow depends on it's location).
In smaller bones, instead of marrow, the bone would be filled with more spongy bone.
Bones are rigid organs that constitute part of the endoskeleton of vertebrates. They support, and protect the various organs of the body, produce red and white blood cells and store minerals. Bone tissue is a type of dense connective tissue. Bones come in a variety of shapes and have a complex internal and external structure, are lightweight yet strong and hard, and serve multiple functions. One of the types of tissue that makes up bone is the mineralized osseous tissue, also called bone tissue, that gives it rigidity and a coral-like three-dimensional internal structure. Other types of tissue found in bones include marrow, endosteum, periosteum, nerves, blood vessels and cartilage. At birth, there are over 270. bones in an infant human's body,[1] but many of these fuse together as the child grows, leaving a total of 206 separate bones in an adult. The largest bone in the human body is the femur and the smallest bones are auditory ossicles.[

What category of the bone is composed of two layers of compact bone sandwhichng a layer of spongy bone?
diaphysis
Does the stenum has two layers of compact bone with a layer of spongy bone sandwiched in between?
Yes, the sternum contains two layers of compact bone with a layer of spongy bone sandwiched in between. This structure provides strength and support to the chest area, protecting vital organs such as the heart and lungs.

What type of bone is arranged in concentric layers?
Compact bone tissue is arranged in concentric layers called lamellae around a central canal that contains blood vessels and nerves. These layers give compact bone its strength and resilience, helping to support the body and protect vital organs.
