The German noun 'Knochen' translates to 'bone' in English. It refers to the hard, rigid organ that forms part of the skeleton of vertebrates. Bones provide support and shape to the body, protect internal organs, produce blood cells, and store minerals.
In human anatomy, there are around 206 bones in an adult skeleton. These bones are classified into different types based on their shape and function. Some examples include long bones (such as the femur), short bones (such as the carpals in the wrist), flat bones (such as the scapula), and irregular bones (such as the vertebrae).
Bones are composed of a dense outer layer called cortical bone and a spongy inner layer called trabecular bone. They consist mainly of collagen fibers and calcium phosphate, which gives them their strength and hardness. Bone tissue is constantly being remodeled through a process called bone remodeling, where old bone is broken down by cells called osteoclasts and new bone is formed by cells called osteoblasts.
