luurakenteet
Luurakenteet refers to the structural elements of bones within the skeletal system. Bones are complex living tissues that provide support, protection, and facilitate movement. The overall structure of a bone consists of an outer layer of dense, hard bone called compact bone, and an inner layer of spongy, porous bone called cancellous bone. Within the cancellous bone are marrow cavities, which contain either red bone marrow responsible for producing blood cells, or yellow bone marrow, composed mainly of fat.
The microscopic structure of bone is also a key aspect of luurakenteet. Compact bone is organized into
Bone tissue undergoes constant remodeling, a process where old bone is removed and new bone is formed.
