Types of Bones
There are five major types of bones as below:
- Long Bones: Their length is more than their width. The long bones in the human body are present in legs and arms. These bones are femur, tibia, fibula of legs and humerus, radius and ulna of arms.
- Short Bones: They are as long as they are wide. These bones are cuboid shaped. Examples: Bones of wrist and ankle.
- Flat Bones: The name suggests the shape and surface of bones is flat. They are typical bones with the compact layer, spongy layer and bone marrow. Examples: Ribs, skull bones, sternum, and shoulder bones.
- Irregular Bones: Irregular bones do not possess any specific shape and thus are called irregular. They play a role in giving protection to internal delicate structures such as Vertebrae giving protection to the spine.
- Sesamoid Bones: This type of bone is small and embedded in muscles or tendons. This type of bone is present at the joints. Example: Patella bone of knee.
Bone Anatomy – Functions, and Types
Bones are essential organs of the skeletal system in vertebrates, providing structural support and protection to internal organs. They also facilitate movement, blood cell production, and mineral storage. Bones in the human body are made of bone tissue, cartilage, marrow, blood vessels, and nerves.
Each bone has a specific function and shape. Bone growth and remodeling occur throughout life. These processes are regulated by ossification and bone resorption. Let us discuss bones, their structure, function, and more in detail.
