Long bone
Cylinder-like, long than it is wide. Such as femur
Long bones are bones that are longer than they are wide and have a distinct shaft or diaphysis with two bulbous ends known as epiphyses. They make up the majority of the bones in the body, such as the femur, tibia, fibula, humerus, ulna, and radius.
Long bones are composed of three main parts: the diaphysis, the epiphysis, and the metaphysis. The diaphysis is the cylindrical or elongated portion of the bone, while the epiphysis is the rounded end of the bone that forms a joint with another bone. The metaphysis is the transitional area between the diaphysis and the epiphysis.
The interior of long bones contains the bone marrow, a soft tissue that produces blood cells. The outer surface of long bones is covered by a layer of connective tissue known as periosteum, which provides nourishment to the bone and serves as an attachment site for muscles and ligaments.
Long bones play a crucial role in the body’s structural support and movement. They also protect vital organs, such as the brain, heart, and lungs. Additionally, long bones store minerals, such as calcium and phosphorus, which contribute to bone strength and overall health.
