The inside of a bone is filled with a soft tissue called bone marrow. There are two types of bone marrow: red and yellow. Red bone marrow is responsible for producing blood cells and platelets, while yellow bone marrow primarily stores fat.
In addition to bone marrow, the inside of a bone also contains:
- Blood vessels: These carry blood to and from the bone, providing nutrients and oxygen.
- Nerves: These transmit signals to and from the bone, allowing it to sense pain and pressure.
- Cancellous bone: This spongy, porous type of bone is found inside compact bone and helps to reduce the weight of the bone while providing strength.
- Compact bone: This dense, hard outer layer of bone provides structural support and protection.
Bones are essential for our body's structure, movement, and overall health. They work together with muscles and joints to form the musculoskeletal system.
