Tissues of the Organs:
Now we know that there are different organs that make up the skeletal system, but what makes up these organs?
Bones
Bone Marrow
Red bone marrow is found in the spongy bone part of the bones, and it plays a very important part in keeping us functioning properly. Red bone marrow in our bones in in charge of creating red blood cells, white blood cells and platelets. Without these three things we would not have a circulatory system which works with the other systems to keep us alive. As a person gets older a lot of the red bone marrow becomes yellow bone marrow which is mostly made of adipose cells. Although this means that there are less blood cells, yellow bone marrow is a very good storage place for chemical energy in the body.
Bone Matrix
Bone matrix is a non-living substance that is found between the cells of the bones. It contains calcium, phosphorus and proteins. The bone matrix helps replace calcium that is taken from the bones by calcium from the diet. This function gives the bones the strength they need to protect and support the body.
Osteocytes
Osteocytes are just another name for bone cells. The osteocytes have the job of regulating the amount of calcium put in or taken out of the bone matrix.
Compact Bone
Compact bone is a solid very precisely structured type of bone. The compact bone is made of haversian systems. Haversian systems contain osteocytes, bone matrix and blood vessels. Compact bone is just one type of tissue that makes up one type of bone.
Spongy Bone
Unlike compact bone, spongy bone actually looks like a bone with a lot of visible holes and cavities. Like the compact bone, spongy bone contains osteocytes, blood matrix and blood vessels, but they are NOT arranged in haversian systems. It is in the cavities of the spongy bone where red blood marrow can be found.
Periosteum
Periosteum is a tissue that covers the surface of the bones. It is a fibrous connective tissue who's collagen fibers merge with those of the tendons and ligaments. This allows the bones to anchor to the tendons and ligaments. Periosteum also contains blood vessels that enter into the bone.

Cartilage, Ligaments and Tendons
Fibrous Connective Tissue
Cartilage, ligaments and tendons are made of one type of tissue; fibrous connective tissue. Fibrous connective tissue is a type of connective tissue made of collagenous fibers. The collagenous fibers give the fibrous connective tissue a relatively high amount of durability. Fibrous connective tissue also forms the ligaments and tendons and is mostly made of non-living cells. It mainly consists of different complex carbohydrates, water and proteins.
